Aftermarket Control Arms for Lifted Trucks and Off-Road Rigs

Control arms are the geometric foundation of your suspension. They define where your wheel sits in relation to the chassis through the full range of suspension travel. When you lift a truck, OEM control arms create geometry compromises that aftermarket units are specifically designed to solve.

Why Lifted Rigs Need Aftermarket Control Arms

OEM control arms are engineered for OEM ride height. Add lift and the ball joint angles change — in some cases dramatically. On IFS trucks, upper ball joint angles at lifted ride height can exceed the joint's design limits, accelerating wear and risking failure. Aftermarket UCAs move the ball joint to a position that restores proper angles at lifted ride height.

Extended lower control arms push the wheel forward to correct caster, which improves high-speed stability on lifted rigs. This is particularly important on trucks running 3+ inches of lift — without caster correction, the truck will wander at highway speeds.

Control Arms and Limit Straps: A Complete System

Control arms define suspension geometry through the range of travel. Limit straps define where that range of travel ends. Both are essential for a suspension system that performs correctly and doesn't destroy itself.

Without droop limits, your control arm ball joints, CV axles, and brake lines will all see angles they're not designed for at full extension. Bull Strap limit straps set a mechanical endpoint for suspension droop, protecting every joint in the system. Set them after your control arms are installed, sized to keep all angles within safe limits throughout the travel range.

Installation Sequence

Install control arms first to establish your lifted geometry. Then set limit straps at the droop point where ball joint and CV angles remain safe. Then size extended brake lines to reach that droop point with clearance. Then align — because your geometry has changed and alignment needs to be set at the new ride height. This sequence ensures every component is specced correctly relative to everything else.
