The rear axle (and tire) are forced towards the race track. Clamp brackets are sometimes used on short, slick tracks to improve initial forward bite. So again, unlike the GM and Dana axles that require a unique differential with different ratios, the Ford 8.8-inch differential is common across all of the ring-and-pinion ratios. Two rear axles are placed in between the differential and the wheels. The axle tag is bolted to the rear differential cover, and is held on with one of the cover bolts. Custom Axle Kits typically take 1 week to design and 4-6 weeks to manufacture. Mounting the left coil-over unit ahead of the axle (on a clamp bracket) generally tightens corner handling.
