Brad introduces a detailed look at a Jeep Gladiator built with clear intent and real-world use in mind. He speaks as a fellow off-roader who wants to understand not just what parts went into the truck, but why each choice mattered, especially since the owner works on Jeeps for a living.
The video focuses on Jerry’s 2021 Gladiator Rubicon and the path it took from a mostly stock truck to a serious rock crawler. Brad sets the stage for a full walkaround that explains the build decisions, trail experience, and practical upgrades that shaped how the truck performs today.
Key Takeaways
- The build reflects hands-on experience and careful choices.
- The truck balances daily use with tough trail demands.
- Each upgrade serves a clear purpose, not just looks.
Owner Background and Build Philosophy
Professional Jeep Experience
He has worked as a Jeep technician for more than a decade. He also co-owns an off-road shop, where he works on these vehicles every day.
That daily hands-on work shaped how he approaches builds. He focuses on parts and methods he trusts because he sees what lasts and what fails.
Key background points:
- Over 10 years as a Jeep technician
- Co-owner of an off-road shop
- Regular trail time and real-world testing
Build Direction and Intent
He did not plan this build to start as an extreme setup. He first wanted a Gladiator that stayed close to factory style while adding capability.
Over time, his goals changed as his driving skills grew. He pushed the truck toward harder trails and rock crawling as his confidence increased.
Guiding ideas behind the build:
- Keep systems reliable and well maintained
- Choose function over trend
- Let trail use guide each upgrade
Decision to Let It Go
He plans to sell the Gladiator because he has another project lined up. Carrying two vehicle payments does not make sense for him.
He wants the truck to move on to someone who will use it. The sale supports his next build rather than ending his interest in off-road projects.
Base Vehicle Details
2021 Gladiator Rubicon Platform
- The truck is a 2021 Jeep Gladiator Rubicon.
- He chose the Rubicon trim because it offers strong off-road capability from the factory.
- The build started with the goal of keeping a near‑OEM look while improving trail performance.
| Item | Detail |
|---|---|
| Model Year | 2021 |
| Vehicle Type | Mid-size pickup |
| Trim | Rubicon |
| Original Intent | Mild upgrades with factory-style appearance |
Why Gladiator Instead of Wrangler
- He wanted a truck, not just an SUV, so he first looked at a Ram 1500.
- He ruled it out because it would not handle off-road use the way he wanted.
- The Gladiator fit his needs by offering a pickup bed with real trail capability.
- Compared to a Wrangler, the Gladiator gave him more utility while still working well on difficult trails.
Engine, Maintenance, and Performance Upgrades
Regular Service and Care
He keeps the engine close to stock and focuses on steady upkeep. He changes the oil about every 5,000 miles and checks coolant levels often.
He handles all service himself and stays consistent. This approach keeps the engine running well without added tuning.
Intake Setup and Engine Add-Ons
He avoids engine tuning and forced induction. He uses a programmer only to set tire size and gear ratios.
He installed a cold air intake with a covered filter. The cover helps block dirt while still allowing airflow.
Dual Battery Power Setup
He runs a Genesis dual battery system with an integrated top module. The system manages both batteries on its own and keeps wiring organized.
It maintains proper voltage and includes clean mounting points for accessories. It also combines batteries only when needed.
Cylinder Head and Cooling Fixes
Around 35,000–40,000 miles, he noticed coolant loss. This issue is known on this engine, so he addressed it right away.
He removed the cylinder heads and installed new gaskets. He also applied a sealant to fill small surface flaws and prevent future leaks. At about 57,000 miles, the repair continues to hold.
Working Hood Ventilation
The hood scoops serve real cooling functions. One directs air toward the exhaust and catalytic converter on the driver side.
The other feeds air into the intake path. These scoops replace the factory parts and required trimming insulation during install.
Exterior Lighting and Accessories
KC Pro6 Light Bar with Flex 4 Pods
He runs a KC Pro6 light bar on the roof and pairs it with Flex 4 lights. He angles the Flex 4s outward to widen the beam and add side lighting.
These lights use a combo pattern, which helps cover both distance and nearby terrain.
- Light brand: KC HiLiTES
- Setup goal: clear forward and side visibility
- Use case: night trail driving and technical routes
Body-Color Light Mounts
He did not keep the mounts black. He painted them to match the Jeep’s exterior color.
He wanted the lights to blend in and look clean rather than stand out.
Details:
- Painted, not powder coated
- Chosen for a more factory-style look
- Matches the body color for a uniform finish
Antenna and Radio Bracket Setup
He mounted the radio antenna using a KC rock light bracket. He modified the bracket to hold the antenna securely.
This approach keeps the install simple and tidy.
| Item | Notes |
|---|---|
| Radio | Midland |
| Mount base | KC rock light bracket |
| Result | Clean fit with no clutter |
Armor and Protection
Motobilt Tomahawk Frame-Cut Front Bumper
He chose a compact steel bumper that requires trimming the front frame. The design improves approach clearance and opens space around the front end. He finished it in black powder coat for a clean, factory-like look.
Key details
- Material: thick steel plate
- Fitment: frame-cut install
- Benefit: more clearance up front
Warn VR Series Recovery Winch
He runs a Warn VR winch sized to handle the weight of the truck. He has used it once during a recovery and it performed as expected. The winch offers enough pulling power for trail use without extra complexity.
| Feature | Notes |
|---|---|
| Brand | Warn |
| Use | Occasional recovery |
| Power | Adequate for this build |
Trimmed Factory Fenders with Reinforced Clips
He kept the stock fenders but cut them for tire clearance. He replaced the factory clips with stronger retainers to keep the panels secure. This setup supports larger tires without switching to aftermarket fenders.
- Stock fenders, modified
- Stronger clip retainers
- More room at full flex
Quake LED Fender Lighting
He added LED lights inside the fender openings. The lights improve visibility and fit cleanly within the modified fenders. He noted they work well and suit the build.
Lighting location: inside the fenders
Purpose: added light around the wheels
Locking Hood Retainers
He swapped the factory hood latches for lockable units. The design keeps an OEM look while adding security. He values the clean fit and the ability to lock the hood.
- Brand: Rugged Ridge
- Style: factory appearance
- Function: locking security
Wheels, Tires, and Brakes
Mud-Terrain Tires by Nitto
He runs 40×13.50R17 Nitto Trail Grappler mud-terrain tires.
He chose them to handle hard trails and rock crawling without trouble.
They support the aggressive setup he built over time.
Raceline Beadlock Wheels
The tires sit on Raceline Rhino 17-inch beadlock wheels.
He picked the beadlock design for secure tire seating at low air pressure.
He went with a polished finish, even though he did not expect to like it, and says it works well on this truck.
Teraflex Brake System Upgrade
He upgraded the factory brakes with a Teraflex Delta brake kit.
He wanted stronger stopping power and a firmer pedal feel.
He says the truck stops confidently and does not feel heavy, even on 40-inch tires.
Axle and Drivetrain Enhancements
Strengthened Factory Rubicon Housings
He focused on reinforcing the stock Rubicon axles to handle hard rock use. The changes aim to reduce flex and lower the risk of failure on tough trails.
Heavy-Duty RCV Axle Shafts
He upgraded to RCV axle shafts for added strength at the wheels. These shafts support larger tires and sustained use under load.
Lower Gearing With 5.13 Ratios
He re-geared the axles to a 5.13 ratio to match the tire size. This setup improves control at low speed and restores proper drivability.
Reinforced Steering Knuckles
He installed stronger aftermarket knuckles to replace the factory parts. These components help manage stress from larger tires and steering loads.
Axle Truss Reinforcement
He added truss systems to stiffen the axle housings. The trusses help keep the axles straight during hard crawling.
Upgraded 1350-Series Driveshafts
He moved to 1350 driveshafts for higher strength at the joints. This upgrade supports the added torque from gearing and tire size.
Rear Dana Axle Improvements
He upgraded the rear Dana axle to better match the front setup. The changes support durability and balance across the drivetrain.
Suspension and Steering Systems
Long-Arm Suspension Upgrade
He runs a full long-arm suspension to improve axle movement and control. The setup supports hard rock trails and keeps the suspension stable under load.
The long arms change how the axles move through their travel. This helps the truck stay planted on uneven terrain.
Tuned Coil Spring Configuration
He chose a custom spring setup to match the weight and purpose of the build. The springs balance ride height with flexibility.
This setup supports large tires without relying on extreme lift.
High-End Performance Shocks
He uses premium Fox shocks designed for off-road use. The shocks manage heat and control movement on slow, technical trails.
They help keep the tires in contact with the ground during climbs and drops.
Reinforced Steering Components
He upgraded the steering linkage to handle larger tires and trail stress. The stronger parts reduce flex and unwanted movement.
This improves steering feel and reliability on difficult lines.
Advanced Steering Stabilizer
He added a Fox steering stabilizer to control feedback through the wheel. The stabilizer helps manage impacts from rocks and ruts.
It keeps the steering more predictable on rough surfaces.
Adjustable Sway Bar System
He runs an aftermarket sway bar system that allows more articulation off-road. The setup improves axle movement without removing control.
This helps the truck stay stable while still allowing the suspension to work.
Underbody and Frame Protection
Factory and Added Skid Plates
He did not describe any changes to the skid plates. He did not point out added armor or aftermarket panels under the truck during this part of the walkaround.
OEM Rock Rails
He did not mention replacing or modifying the rock sliders. He did not explain any upgrades or removals related to the factory rails.
Mountain Hatch Tailgate Work Surface
He did not talk about a tailgate table or cargo-side work surface. He did not show any accessories mounted inside or on the tailgate.
Rear Bumper Protection Slider
He did not discuss the rear bumper or any rear slider components. He did not note changes to rear protection in this segment.

- Simple, practical design
Cargo Space Planning
He balances the spare tire with usable bed space. He places gear so it stays secure and does not interfere with trail performance. The layout supports hard trails without adding clutter.
| Priority | Reason |
|---|---|
| Secure storage | Prevents movement on rough terrain |
| Clearance | Supports rock crawling |
| Simple layout | Keeps the build functional |
Driving Experience and Trail Performance
Trail Recon Extreme Challenge Run
He drove this Gladiator through the Trail Recon Extreme Challenge, which ranks as a hard and demanding trail. The truck completed the entire route without mechanical trouble. The run pushed both the vehicle and the driver, but it finished the course as planned.
Key outcome from the challenge:
- Finished the full trail
- No major issues during the run
- Proved the build worked as intended
Notable Obstacles and Trail Behavior
The trail required careful tire placement and steady control through technical sections. The Gladiator stayed composed while climbing and crawling over difficult terrain. The setup allowed him to focus on driving lines instead of worrying about vehicle limits.
| Aspect | On-Trail Behavior |
|---|---|
| Traction | Consistent on tough sections |
| Control | Predictable and steady |
| Clearance | Handled obstacles without hang-ups |
Reflections on Off-Road Capability
Completing the challenge changed how he viewed the truck’s abilities. The experience increased his trust in the build and confirmed it could handle harder trails than expected. The trail run served as a real-world test, not a show setup or light-duty use case.
Suggested Future Improvements
Additional Undercarriage Protection
He built the Gladiator for hard trails and high clearance. Extra skid plates would help guard key parts during rock crawling. This would add protection without changing how the truck drives or looks.
Possible benefits
- Protects the oil pan, transmission, and transfer case
- Reduces risk of trail damage
- Fits the current rock-focused setup
Thoughts on a 392 V8 Conversion
He kept the 3.6L engine mostly stock and focused on maintenance. He showed caution with power adders and avoided forced induction. A 392 swap would add power, but it would require major changes and careful planning.
Key considerations
- Large cost compared to current setup
- More stress on drivetrain parts
- Would move away from his simple, reliable approach
Option for an Atlas Transfer Case
The truck already handles difficult trails with confidence. An Atlas transfer case could offer more control for slow, technical driving. This upgrade would target extreme crawling rather than general use.
What it could improve
- Lower crawl ratios
- Better control on steep obstacles
- Strong match for dedicated rock use
