When it comes to performance driving, traction is the name of the game. In order to get the maximum amount of power to the ground, traction aiding devices like Buick Rainier limited slip differentials are a necessity. In addition, if you take your vehicle off road or drive in slippery/wet conditions like snow or ice, limited slip differentials will deliver the traction you need to get safely down the road or trail. Here at Andy's Auto Sport we have a great selection of Buick Rainier limited slip differentials. From the budget minded enthusiast to the high-end user, we have the best models from all of the top brands to ensure that you find the perfect Buick Rainier limited slip differential to suit your needs.

The basic idea of a differential is to allow the drive wheels to spin at independent speeds to provide smooth operation during cornering. But a huge limitation of this design is that power is only delivered to on wheel, usually the wheel with the least amount of grip. This can leave you stuck in the mud spinning only one wheel or cost you time on the track due to reduced traction. A limited slip differential solves this problem by delivering power to both drive wheels ensuring maximum adhesion and allowing you to keep moving forward. There are varying styles of Buick Rainier limited slips from clutch actuated units that only partially engage both wheels, to models that act more like full lockers. We recommend that you figure out what type of driving you'll be doing the most and pick out the correct differential for those conditions.
