Yukon Gear YA F880008 Differential Review

Based on my observations, the performance of this product fell far short of my expectations. The installation process was complicated and cumbersome which made the experience frustrating. While it did improve the cars overall performance somewhat, the added benefits did not justify the high cost of the product..

I have a pair of these for my '90 F150 that runs 11 seconds per 1/4 mile. The originals have done 150,000 miles and are worn out. There are other options here at Revain that are cheaper but I bought them again for my Mustang because the quality is really good.
