What causes driveline vibrations after lowering a truck?

Lowering a truck changes the angle of the driveshaft relative to the transmission and rear differential. When these angles become too steep or misaligned, it can cause vibrations, especially during acceleration. This kit helps correct those angles.

What parts are included in this driveline alignment kit?

The kit includes pinion shims to adjust the rear differential angle, a transmission spacer, and a carrier bearing spacer. It also comes with Grade 8 hardware and installation instructions.

Will this kit work with any driveshaft setup?

No, this specific kit is designed for vehicles with a two-piece driveshaft. It is intended for use on 1988-1998 Chevrolet and GMC C/K series trucks and Suburbans that have had their suspension lowered.

Product Details

When you lower a truck, especially one with a two-piece driveshaft like many 1988-1998 GM C/K series pickups and Suburbans, the driveline angles change. This can lead to annoying vibrations when you accelerate. If the standard drop kit isn't enough to correct these angles, Belltech's Driveline Alignment Kit is the solution you need.

This kit includes everything to help get your driveline angles back in spec. You'll find pinion shims to adjust the rear differential angle, along with a transmission and carrier bearing spacer. These spacers help correct the angle of the driveshaft itself and the center support bearing. It all comes with Grade 8 hardware, which is strong stuff, and instructions specific to your truck to make the job straightforward.

By addressing these critical angles, this kit helps eliminate those unwanted vibrations, making your lowered truck feel smooth and right again. It's a well-built solution for a common issue when modifying your suspension.
