Important Notes
- 18" or larger diameter wheels required. Stock 17" and 18" wheels cannot be re-installed. Stock 20" wheels can be used with up to a 305/60R20 tire.
- 18" wheels with 5-5.5" backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle/tie rod. 5.5" backspacing is highly recommended for tire to frame crash bar clearance.
- Models with 2-piece rear driveshaft WILL require carrier bearing shim kit 122406 (not included w/ kit)
- Block kits replace factory 1-1/4" block. Stock block will not be reinstalled.
- Crash bars may require modification based on wheel and tire choice. It is the end users responsibility to ensure modifications are non-detrimental to vehicle safety.
- Does NOT fit diesel models.
- Tremor models: only the 3-1/4" rear block is recommended. Larger blocks cause driveline vibration. Expected rake is 1" with new block installed. Factory block provides slight tail low stance if desired
- Some trucks with a 2 piece drive shaft may have a recall from Ford regarding the rear driveshaft. (Safety Recall 21S25) Due to the recall procedure, BDS recommends to have this performed prior to installing the lift.
- Will not work with models with CCD (Continuous Controlled Damping)
- Requires frame bracket modification.
Features & Benefits
- FOX 2.0 Performance IFP shocks eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving
- High clearance crossmembers improve strength and offroad capability
- Heavy duty steering knuckles to correct steering geometry and maintain ESC system compatibility
- Top mounted strut spacers to provide lift and install easily
- Differential skid plate for improved offroad protection
- Rear lift blocks and u-bolts to lift and level the stance
Increase the performance and capability of the 2021-2024 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" 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" extruded and machined 6061 T6 aluminum body for better heat dispersion, along with an internal floating piston (IFP) to eliminate oil aeration, FOX's proprietary internals, 5/8" 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.
