Description

IMPORTANT NOTICE: For use on diesel engine models only. Will not work on Super Duty's with height sensors.

ReadyLift Suspension tubular radius arm upgrade kits are designed to correct the suspension geometry on lifted models. These new radius arms are heavy-duty and built to handle the use and abuse demanded out of Super Duty trucks. The arms are formed inward, allowing for additional clearance and providing even more space for oversized tires. The direct bolt-on design promotes quick and easy installation. The arms are available for a variety of late-model trucks.

Additional details:

* Heavy-duty tubular construction
* Machined from steel with a black powdercoat finish
* Designed to correct suspension geometry on 3.5 in. to 6 in. lifted models
* Helps to correct the caster angle
* Allows for larger tires to be installed
* Ease of installation with direct bolt-on design
* Oversized rubber bushings to better isolate road noise and vibration harshness
* Notes: Will not work on Super Duty's with height sensors

Includes:

* Radius arm, left, assembled
* Radius Arm, right, assembled
* Cam bolt kit
