2008 Cummins Long Arm 8" 4-Link Lift Kit (BDS641H)
Lifting your truck with some lift kits can sometimes make the driving dynamics like walking on stilts after a couple of wobbly pops. This is unfortunate because you want your lift kit to give you the stance while not sacrificing drivability! That's where the BDS Suspension 8" Long Arm Kit for the 2008 Cummins comes in. All components in this kit aid in reducing caster change, increasing control, stability, steering angles, & are powder coated for long-term performance.
