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
- Some vehicles may require rear driveshaft spacer kit 122007 to maintain adequate rear driveshaft engagement
- Will not fit Cab and Chassis models
