2001-2010 Duramax 4.5" Lift Kit (BDS192H)
Lift up your GM truck or SUV with this BDS suspension 4.5" Lift kit. This kit utilizes high arched crossmembers that blend perfectly with the angle of the factory-installed lower control arms for a completely integrated look while lifting your vehicle a full 4-1/2" dramatically increasing ground clearance at the front crossmembers and improving operating geometry. A front differential skid plate comes standard, for increased off-road protection.

- 35" x 12.50" w/17 or 18 x 9 and 5.5" back spacing

Note: This selection is just for reference purposes
This system is available with two different knuckle designs. The standard knuckle widens the track but does not affect the turning radius. The narrow track knuckle reduces the total track width change by about 1.5" overall but does increase the turning radius slightly.
