Trailing Arms with Fitting Position Front Axle, Rear Axle for JEEP WRANGLER JK

JK WRANGLER Trailing arms are suspension components that control the longitudinal and lateral position of the axle relative to the chassis, maintaining correct axle location through the full range of suspension travel. On solid axle 4WD and off-road platforms, the trailing arms at the front and rear axle play a critical role in determining pinion angle, and when a vehicle is lifted, the change in ride height shifts the axle out of its factory alignment position. This results in incorrect pinion angle, increased drivetrain vibration and accelerated wear through the tailshaft, universal joints and differential components.

JK WRANGLER Adjustable trailing arms allow the pinion angle to be corrected at the new ride height, restoring correct axle geometry and eliminating the vibration and wear associated with incorrect pinion angle on lifted solid axle platforms. For passenger vehicle applications, direct replacement trailing arm assemblies restore correct rear axle and wheel geometry following wear or damage. A comprehensive arm solution for workshops and experienced DIY users across lifted 4WD, off-road and applications. Installation guides are available across most products.

Why Upgrade JK WRANGLER Suspension?

On lifted solid axle 4WDs and off-road platforms, factory trailing arms are designed around the vehicle's standard ride height and cannot correct pinion angle once the suspension geometry has been altered. Incorrect pinion angle causes the tailshaft and universal joints to operate at angles outside their designed range, resulting in vibration, noise and premature wear that worsens as lift height increases and mileage accumulates.

Replacing factory trailing arms with adjustable alternatives allows pinion angle to be set correctly at the new ride height, eliminating drivetrain vibration and protecting tailshaft, universal joint and differential components from the accelerated wear associated with incorrect geometry. For the JK WRANGLER, worn trailing arm assemblies introduce rear axle play, handling imprecision and geometry drift that affects tyre wear and rear end stability under braking and cornering.

JK WRANGLER Trailing Arm Range

The JK WRANGLER trailing arm range includes:

• JK WRANGLER Adjustable Rear Upper Trailing Arm Kits: On-car adjustable paired rear upper trailing arms for solid axle 4WD applications, allowing pinion angle to be corrected without removing the arms from the vehicle. Designed for lifted and off-road use.
• JK WRANGLER Adjustable Rear Lower Trailing Arm Kits: Off-car adjustable paired rear lower trailing arms for solid axle 4WD and off-road applications, providing pinion angle correction at the rear axle following a suspension lift.
• JK WRANGLER Adjustable Front Upper Control Arm Kits: On-car or off-car adjustable paired front upper control arms for solid axle 4WD and off-road applications, providing pinion angle correction at the front axle following a suspension lift.
• JK WRANGLER Adjustable Front Lower Control Arm Kits: Off-car adjustable paired front lower control arms for solid axle 4WD and off-road platforms requiring front pinion angle correction at the new ride height.
• JK WRANGLER Rear Trailing Arm Assemblies: Direct replacement rear trailing arm assemblies for passenger vehicles, restoring correct rear axle geometry and suspension performance following wear or damage.

Why Purchase JK WRANGLER Trailing Arms?

Running a lifted solid axle vehicle with factory trailing arms risks ongoing drivetrain vibration, noise and premature wear through the tailshaft, universal joints and differential. Using adjustable trailing arms to correct pinion angle at the new ride height eliminates vibration, protects drivetrain components and ensures the suspension operates reliably and safely following the modification.

For workshops completing suspension lift installations on solid axle 4WDs and off-road platforms, adjustable trailing arms are an important part of ensuring correct geometry outcomes and protecting the drivetrain from post-lift wear. For JK WRANGLER owners and experienced DIY users, fitting correctly specified adjustable arms as part of a lift installation ensures the JK WRANGLER performs reliably and safely off-road at the new ride height.

Installation and Support

JK WRANGLER Trailing arms and adjustable control arms are designed for accurate installation at the front and rear axle mounting positions. On-car adjustable arms can be set to the correct pinion angle with the arms in place, while off-car adjustable arms are set to the required length before installation. Installation time is approximately two hours across all products. For additional technical assistance, a dedicated support team is available to help ensure correct product selection and pinion angle setting for the specific lift height and application.

Repair and Upgrade

JK WRANGLER Trailing arms and adjustable control arms are manufactured from high-strength materials engineered to withstand the load, vibration and environmental exposure that solid axle suspension and drivetrain components are subject to in demanding off-road use. Designed as targeted geometry correction and direct repair solutions, each arm restores correct axle and pinion angle geometry across a range of lifted 4WD, off-road and passenger vehicle applications.

Who JK WRANGLER Trailing Arms Are For

JK WRANGLER Trailing arms are a practical solution for:

• Professional workshops completing suspension lift installations on solid axle 4WDs and off-road platforms requiring adjustable trailing arms and control arms to correct pinion angle and protect the drivetrain at the new ride height.
• Experienced DIY users fitting a lift kit to a solid axle 4WD or off-road vehicle who need adjustable arms to correct front and rear pinion angle and eliminate drivetrain vibration.
• 4WD enthusiasts and off-road vehicle owners experiencing drivetrain vibration, noise or universal joint wear following a suspension lift that cannot be resolved without correcting pinion angle through adjustable arms.
• Passenger vehicle owners and workshops requiring direct rear trailing arm replacement to restore correct rear axle geometry and suspension performance.

The right trailing arms restore correct axle and pinion angle geometry, protect drivetrain components and deliver reliable, vibration-free suspension performance at the new ride height every time.
