SLP STRONGLY recommends the use of this kit for all such installations. NOTE: Compatible with stock, SLP #64501T (OEM replacement), and SLP #65002 (heavy-duty) differentials. http://www.bestperformanceautoparts.com/bp/SLP-64002.html http://www.bestperformanceautoparts.com/bp/SLP-64002.html Drivetrain Ring and Pinion, 4.10, Gear Set 7.5 inch and 7.625 inch Differential One of the best ways to improve your car's acceleration is to lower your rear-axle ratio. SLP offers 3.42:1, 3.73:1, and 4.10:1 ratios for the GM 7.5 inch and 7.625 inch differentials, which are found in 1993-2002 F-Bodies and in some S-series trucks. These gears are manufactured by AAM to OEM specs and tolerances, ensuring both long life and quiet operation. Available as a ring-and-pinion set only, or in kit form with an Auburn differential and installation kit. NOTES: Installation Kit (Part #64047) recommended. SLP Custom DiabloSport II Programmer (Part #27007T) recommended. 4.10 Gear Sets Require Paddle-Pin Kit (Part #64002) to complete installation on vehicles equipped with a Zexel-Torsen differential. Please check your stock differential prior to purchasing, as some applications will require a reluctor ring for proper installation.
