BDS 4 Inch Lift Kit w/ 4-Link | Ford F250/F350 Super Duty (2011-2016) 4WD Gas | Block Kit | NX2 Nitro Series Shocks

This variant uses a Block Kit rear lift configuration. Rear lift blocks are cast iron for strength, tapered for correct pinion angle, with an offset steel pin and hole to restore axle position. The multi-leaf progressive design maintains factory payload weight ratings and reduces axle wrap for a more controlled, stable feel.

Equipped with NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends for increased strength, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish. Vehicle-specific valving provides better control on and off-road.

Overview

This 4-inch lift kit with 4-Link conversion from BDS Suspension is designed for 2011–2016 Ford F250 and F350 Super Duty gas-powered trucks. The kit is engineered to improve stance, performance, and capability, providing clearance for up to 35-inch tires. Up front, it includes gas-specific Pro-Ride coil springs, 4-Link control arms with conversion brackets, a forged drop pitman arm, track bar bracket for steering correction, sway bar relocation, brake line brackets, and precision-tuned nitrogen-charged shocks. In the rear, the kit utilizes a high-strength fabricated lift block or leaf springs (depending on variant), a u-bolt flip kit for maximum clearance, and brake line brackets.

4-Link Conversion

The BDS 4-Link conversion replaces the factory stamped steel radius arms to optimize suspension geometry for improved handling, strength, and stability. This bolt-on upgrade uses high-strength 1/4-inch steel brackets to mount HD upper and lower control arms, correcting axle positioning and limiting caster change throughout wheel travel.

Pro-Ride Coil Springs

A pair of full-length, gas-specific Pro-Ride coil springs provide the correct lift height and smooth, predictable ride across various terrains.

Steering Correction

A forged drop pitman arm minimizes steering angle, paired with a heavy-duty track bar drop bracket to keep steering geometry in phase through suspension travel while recentering the front axle.

Important Notes

• Removal of factory block required.
• Rear add-a-leaf is required for models equipped with factory 3-7/8" block for level to tail-high stance. Single add-a-leaf kit #113218 recommended for more level stance; dual add-a-leaf kit #113209 recommended for tail-high stance. (Add-a-leafs do not apply to rear leaf spring equipped systems.)
• Front exhaust modification may be required to clear front drive shaft (gas only).
• If equipped with a 2-piece driveshaft, a driveshaft alignment kit may be required.
• Although extremely rare, front and/or rear driveline vibration may occur.
• If equipped with rear sway bar, #123009 is required.
• U-bolts will not work on dually models.
