Description
Increase the performance and capability of the 2021-2025 Ford F150 trucks with 4-inch lift kit with FOX 2.0 struts by BDS Suspension. Designed to improve stance the BDS 4 inch lift kit with FOX 2.0 front struts give more capability off-road. This kit includes everything necessary to set your F150 truck up right with clearance for up to 35 inch Tires.
This kit takes advantage of BDS's tried and true high-clearance design for improved ground clearance, strength, and offroad protection while correcting suspension and steering geometry for great on-road handling characteristics.
Up front the kit utilizes FOX 2.0 strut shocks, high-arched 1/4-inch thick steel crossmembers, multipiece differential relocation brackets and skidplate designed for offroad protection.
Steering geometry is corrected at the new taller ride height with a pair of massive CNC-machined ductile iron steering knuckles. These combined with the provided sway bar relocation brackets, brake line brackets, alignment cam bolts, supplied hardware and more provide a comprehensive front suspension lift ready for use and abuse.
In the rear BDS utilizes high strength fabricated lift blocks and longer u-bolts to lift and level the stance along and NX2 Nitro or optional FOX 2.0 Performance Series shocks.
FOX 2.0 Struts
These FOX 2.0 Performance Series coil-over struts bring impressive damper performance for great ride on and offroad capability designed as a direct bolt-in replacement for the factory strut assemblies while retaining the OE coil spring and top plate.
They feature a 2.0 inch extruded and machined 6061 T6 aluminum body for better heat dispersion, along with an internal floating piston (Internal Floating Piston) to eliminate oil aeration, FOX's proprietary internals, 5/8 inch hard chrome plated heat-treated alloy shaft.
High Clearance Crossmemebers
BDS maximizes ground clearance with their heavy duty 1/4-inch thick laser cut perfect fit crossmembers. Paired with a front skid plate system that bolts together to create a rigid subframe while adding extra protection.
Heavy Duty Steering Knuckles
BDS corrects steering geometry at the new taller ride height using a pair of high-strength, CNC machined ductile cast iron steering knuckle design to work with replacement tie rod ends to maintain steering angles for proper function and ESC compatibility.
