The long wheelbase of the Gladiator makes it a stable towing platform, but it can be a liability on technical trails or tight tracks. To keep your belly off the rocks, you need 3.5 inches of lift and 37" tires.

The TeraFlex Trail Select Performance System is designed for the driver who wants total control over their rig's geometry. By including all eight adjustable Alpine IR Control Arms, this kit allows us to perfectly center your wheels, dial in your caster for zero-drift highway driving, and optimize your rear pinion angle to protect your drivetrain. This is the most complete, high-performance suspension system available for the JT platform.

Why the 8-Arm Performance System?

• 8 Alpine IR Control Arms: These aren't just stronger than factory arms; they feature TeraFlex’s Independent Rotation (IR) Bushings. These bushings allow the arms to rotate 360 degrees without binding. This results in incredible articulation off-road and a significantly smoother, more fluid ride on the highway.
• Falcon SP2 3.3 Fast Adjust Shocks: These shocks are a game-changer for off roaders. Using a 3-position Fast Adjust knob, you can switch from Firm (for the heavy trek up a mountain highway) to Soft (for technical rock crawling) in seconds. The piggyback reservoir ensures that even on the longest washboard FSRs, your shocks stay cool and consistent.
• Forged Adjustable Front Track Bar: Centering the front axle is non-negotiable at 3.5" of lift. This heavy-duty forged track bar ensures your steering geometry is perfectly synchronized, eliminating the flighty feel common with lesser kits.
• JT-Specific Coil Springs: TeraFlex linear springs are engineered to handle the Gladiator's unique load-bearing requirements, ensuring your truck sits level even when the bed is loaded with a rack, tent, and gear.

Key Features

• Total Adjustability: 8 Alpine IR arms allow for perfect alignment of caster, camber, and pinion angles.
• Dial-A-Ride Damping: Falcon 3.3 shocks offer three quick-select settings plus a micro-adjust dial for fine-tuning.
• Independent Rotation Bushings: Improves suspension travel and ride quality by removing bushing bind.
• Complete Trail Geometry: Includes a forged adjustable front track bar, rear track bar bracket, and extended sway bar links.

Pro Tip: If you’re building a forever Gladiator, this is the kit. The jump from drop brackets to eight adjustable arms is massive. It allows us to push the rear axle back slightly to perfectly center 37s in the wheel wells and get the front caster exactly where it needs to be for a one-finger highway drive. The Falcon 3.3s are the icing on the cake  and being able to stiffen the rear shocks when you’re towing a trailer and then soften them for the trail makes this one of the most versatile setups we sell.
