What causes driveline vibrations when a truck is lowered?

Lowering a vehicle changes the angle of the driveshaft relative to the transmission and rear differential. If these angles become too steep or misaligned, it can cause vibrations, especially during acceleration. This kit helps bring those angles back into a more acceptable range.

Does this kit include everything needed for installation?

The kit includes pinion shims, a transmission spacer, a carrier bearing spacer, and Grade 8 hardware. It also comes with installation instructions specific to your vehicle application.

Will this kit work on a one-piece driveshaft?

No, this specific Belltech Driveline Alignment Kit is designed for trucks with a two-piece driveshaft. The components, like the center carrier bearing spacer, are intended to address issues specific to that setup.

About this part

Product Details

When you lower a truck like your 1999-2006 Chevrolet Silverado 1500, the angles of the driveshaft can change. This often leads to annoying vibrations when you accelerate, especially if your truck has a two-piece driveshaft. Belltech's Driveline Alignment Kit is designed to fix that.

This kit includes the parts you need to adjust the pinion angle and the carrier bearing position. You'll get pinion shims to tilt the rear differential, a transmission spacer, and a center carrier bearing spacer. It also comes with Grade 8 hardware, which is strong stuff, and instructions specific to your truck to help you get it installed correctly. It’s a well-built solution to make those driveline vibrations a thing of the past.
