Description
A 3.73 rear axle ratio is the sweet spot for street performance and highway cruising—delivering snappier acceleration off the line without sacrificing top-end efficiency or drivability. If you’re running a GM 10-bolt and want noticeable improvements in launch feel and mid-range pull, this complete gear kit eliminates the guesswork with OEM-quality components ready to install.
This is a full differential gear set, so you get everything needed for a proper rebuild: matched pinion and ring gear, carrier components, and quality bearings. Whether you’re upgrading from a taller ratio or refreshing worn gears, you’ll feel the difference immediately.
