2013-2018 Ram 1500 4WD 6"-3" Lift Kit w/FOX (BDS671F)
BDS Suspension 6" Coil-Over Suspension System for Dodge Ram 1500 4WD 1/2 Ton Pickup. Through a collaborative effort between BDS Suspension and Fox Racing, BDS now offers this 4-6" Dodge 1500 4WD suspension system featuring Fox 2.5" coil-over remote reservoir shocks. This system has been rigorously tested to maximize travel and performance on and off the pavement.
Tire & Wheel Combinations:
- 37" x 12.50" w/ 17 x 9 and 4-1/2"
- 37" x 12.50" w/ 18 or 20 x 9 and 5"
Notes:
- These trucks vary from 1"-3" tail high from the factory. Be sure to measure your vehicle before ordering. The 022209, 022309, and 022509 can all be substituted to achieve the desired stance.
- Rack & Pinion steering system is extremely sensitive to any out-of-round or out-of-balance tire/wheel combination. The larger the tire the less the backspacing, and the more sensitive the system, causing minor steering wheel shimmy.
- Not recommended for AWD models.
- Stock 17" and 18" wheels can not be re-installed. Stock 20" can be reinstalled with a factory tire.
- TRX models will achieve approximately 1" of additional lift. This lift is not recommended for use on the TRX models due to possible CV shaft vibration caused by the additional lift. Instead, consider our 4" lift system for 5" of lift or replace the TRX struts with standard struts for use with this system.
- Will not fit adjustable air suspension-equipped models.
- This kit is FMVSS No.126 Compliant
- This kit will bolt on Eco-Diesel models but it will require an aftermarket front driveshaft.

Fox 2.5 Series Shocks
When you want the best in performance and capability, go with FOX. These race-proven FOX 2.5 factory series remote reservoir coilovers up the ante allowing for next-level damper capability and control all neatly packaged. Designed for bolt-on installation, the engineers at BDS and FOX teamed up to offer this race-winning technology into a bolt-on, pre-tuned Coilover designed to perform and provide correct ride height right out of the box. From valving to spring rate, preload, and hose length these FOX coilovers are designed to take all the guesswork out of setting your vehicle up and are designed to be used with BDS lift systems. These coilovers use a large 2.5" body, 3" coil springs, 7/8" hardened carbon steel shaft, high flow piston, JM92 advanced racing shock oil, CNC machined 6061 T6 ends, and external remote reservoir to improve damper capability across any terrain.

Fox 2.0 Series Shocks (2x)
Improve ride quality and capability with the FOX 2.0 performance series IFP shocks. Specially designed for BDS lift systems, these FOX 2.0 aluminum body shocks offer improved cooling capacity and corrosion protection. These shocks use race-proven vehicle-specific valving along with an internal floating piston (IFP) monotube design to separate the shock oil from high-pressure nitrogen to eliminate aeration and maximize performance on/off-road.

BDS Suspension adds to its lineup of heavy-duty upper control arms (UCA) with new kits available for the 2006-2021 RAM 1500 4WD trucks. These new UCAs are designed for improved strength, great looks, and increased suspension droop travel. They are built from high strength 1-1/2" DOM tubing, fully welded for strength and durability. They use an indexed ball joint cup to correct the ball joint positioning when used with 2-3" leveling kits (#122253) or used on 4-6" suspension lifts (#122252). The frame mounting ends feature durometer-specific rubber bushings for long laster durability and reduced NVHs. At the other end, they utilize an indexed ball joint cup with premium quality MOOG ball joints for smooth, quiet operation and superior corrosion resistance to arms that feature uniballs, poly bushings, or heims. These control arms come finished in a durable semi-gloss black powder coat and include a billet aluminum machined ball joint dust cap that can be removed to easily service the greasable ball joints. They integrate a mounting tab for the factory ABS lines so there's no need to zip tie the lines as is the case with other kits on the market. The control arms come fully assembled for easy installation right out of the box compatible with most leveling and lift kits on the market to increase wheel travel.
