2013-2018 Cummins 4 Link 8" Lift Kit (BDS1614H)
The new 8" system is built around the same 4-link conversion system that is used for the 4" and 6" kits. By converting the stock radius arm front suspension to a 4-link, we are able to better control the caster change through the full suspension travel, create much better handling characteristics and maintain a quality ride unloaded without sacrificing payload.
Tire & Wheel Combinations:
- 40" x 13.50 w/ 17" x 9" and 4.5" - 5.5"
Notes:
- Not for use with factory rear airbag suspensions
- Diesel Only
- Kits come standard with a 6-Bolt indexing ring kit. If equipped with heavy-duty 8-bolt t-case order 122813 in place of 122623
- Carrier bearing drop kit will be required for 2-piece rear driveshaft #122405

Recoil Traction Bar Mounting Kit - (4" Axle/ SRW)

BDS is now offering an HD adjustable front track bar for the RAM 2500 and 3500 trucks. These new track bars are a massive upgrade to the factory unit, constructed from 1-3/8 solid steel stock reinforced with gusseted ends to handle whatever on-road and off-road abuse you can through at it. Adjustments are made at the 1-3/8-12 fine threaded center turnbuckle with pinch bolt ends to allow easy tuning to properly recenter the front axle for a range of lift heights. The track bar is formed for proper clearance around critical front-end components and is designed to easy installation without the need to clear the factory frame and axle mounts. Both ends use high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. Parts come with a high-quality textured black powder coat finish for a great look and excellent corrosion resistance. They are designed for use on 0-3" of lift and can be used in combination with most aftermarket track bar brackets to be used on taller lift heights.
