Upgrade your 2021-2023 Ford F-150 4WD to a Tremor conversion with the F-150 Front Knuckle Kit from ICON Vehicle Dynamics. The steering knuckles 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 ICONs Limited Lifetime Warranty.Additional Attributes:GTIN:00840103425672Material:Ductile IronColor:BlackFinish:PowdercoatedInstruction Manual Included:YesMounting Hardware Included:NoHub Included:NoAxle Included:NoGrade Type:PerformanceAAP_UDA_12:EAAAP_UDA_22:1AAP_UDA_4:55California Proposition 65:WARNING: This product contains chemicals known to the State of California to cause cancer, and birth defects or other reproductive harm.Extended Information:Emissions :Emissions Compliance ExemptLife Cycle Status:Available To OrderPackaging:Quantity of Each:1.0Package UOM:EADimension:29.0000 x 19.0000 x 10.0000 inchesWeight:82.0000 PGPDF:I94000_REVA
