Steeda's race kit is made in-house of billet 6061 aluminum. It provides the strength and support that the OEM bushings need to meet race and performance needs, and it's designed to withstand the abuse seen racing down the 1/4 mile.
The kit is not a permanent modification, meaning it's easy to install and easy to remove. When you purchase this race kit, you'll receive aluminum bushings for the front and rear differential mounting locations. Grade 10.9 hardware is also included with zinc-plated washers.
Please Note: This is a race-only part. It will increase NVH and gear noise. For street and competition use try 5554439 with urethane bushings.
