STEERING KNUCKLES

Upgrade your 2021-2026 Ford F-150 4WD to a Tremor “conversion” with the F-150 Front Knuckle Kit from ICON Vehicle Dynamics. The steering knuckle’s design replicates the suspension geometry of the Ford F-150 Tremor and when paired with ICON F-150 Tremor coilover kits the combination offers a 20% increase in front wheel travel, increased ride height with 3.5-4.5” of front lift over stock, as well as improved ball joint angles. Their single piece, high-strength CNC machined ductile iron construction ensures strength and have been engineered to withstand the stresses of aggressive off-road use while minimizing un-sprung weight and maintaining factory track width. These steering knuckles will stand the test of time with a durable black powder coat finish and are backed by ICON’s Limited Lifetime Warranty.
