Description
If you’re running a GM 8.5 10-bolt rear end and need aggressive acceleration for street or strip duty, a 4.10 ring and pinion kit is the direct path to lower ET times and quicker throttle response. This Allstar Performance kit delivers the gear ratio swap you need without the guesswork—everything you require arrives together, pre-matched and ready to install. Whether you’re tuning a street machine or dialing in a dedicated race car, proper gearing makes the difference between leaving money on the table and extracting every bit of performance your engine can deliver.
