SuperPro TRC1204 HD Adjustable Rear Lower Trailing Arm Set for Jeep Gladiator

Lifting your truck adds ground clearance and often more capability; but it also brings side effects. Among them are geometry changes in the suspension and in longitudinal engine configuration vehicles changes in the rear pinion angle. SuperPro's HD adjustable trailing arm sets allow you to correct the rear pinion angle while also upgrading the bushings for improved performance, durability and higher articulation all in a maintenance-free package. Worn bushings allow significant deflection and movement leading to slower responses, a sloppy drive, irregular and excessive tire wear and diminish every facet of the way your vehicle drives “ while contributing to driver frustration and fatigue. The wear is accelerated and the impact of worn bushings is even greater in upgraded trucks and SUVs where the higher weight and impact of items like larger wheels and tires all work the bushings harder. SuperPro's polyurethane bushings are the culmination of nearly 5 decades of suspension expertise and development in Australia's harshest terrain. Designed with durability as a paramount feature we also bring ride and passenger comfort to the forefront of our development. Your vehicle should treat you as well on the way to and from the trail as it performs on your adventure. Our designs and material compositions retain OEM levels of noise and harshness isolation while delivering superior performance and road manners in all conditions.

Improve the rear suspension geometry of your lifted Jeep Gladiator with the SuperPro TRC1204 HD Adjustable Rear Lower Trailing Arm Set. Lifting a truck can change suspension geometry and rear pinion angle, potentially causing driveline vibration, reduced handling response, uneven tire wear, and accelerated bushing wear. This adjustable trailing arm set helps correct the rear pinion angle while strengthening a critical suspension connection for improved performance and durability.

SuperPro designed the TRC1204 with heavy-duty construction and advanced polyurethane bushings developed through nearly five decades of suspension expertise. The upgraded bushings resist the deflection and movement commonly associated with worn factory components, helping provide more precise suspension response, improved control, and greater articulation. They are particularly beneficial for lifted trucks and SUVs equipped with larger wheels and tires, which place additional loads on suspension bushings during street driving and off-road use.

The maintenance-free SuperPro polyurethane bushing design is engineered to deliver enhanced durability without sacrificing everyday comfort. Its material composition helps retain factory-like noise and harshness isolation while improving road manners in a wide range of driving conditions. The adjustable design allows suspension setup to be tailored for modified vehicles, helping restore driveline alignment after a lift and supporting more predictable performance on the road or trail.

The SuperPro TRC1204 rear lower trailing arm set is supplied as a complete set for the applicable suspension installation. It is a practical upgrade for drivers seeking stronger components, improved geometry correction, and reliable long-term performance from a lifted Jeep Gladiator. Professional installation and a post-installation alignment are recommended.
