4.10 Ratio Rear Gears For Your Lightning
The rear end gears in your 1999-2004 SVT Lightning have the potential to go bad over the years - especially if you drive it like you stole it. These trucks were built to have fun in! If you want to keep moving forward, though, you're going to need to make sure your differential internals are up to par! This kit includes Ford Original gears, bearings and hardware for a complete install. The 4.10:1 ratio will provide better acceleration for faster take off compared to the 3.55 or 3.73 (depending on year) ratio gears your Lightning came with from the factory.
The superior surface finish, hardening, and manufacturing consistency provide the strongest and quietest 9.75" Lightning gears on the market! These are the same Ford gears that have 100,000-mile warranties in Ford production trucks. Higher quality gears means more satisfied customers!
