Description
If you’re building a high-revving street machine or track car, gear ratio is one of the most direct ways to transform acceleration and overall drivability. The Excel 4.10 ring and pinion delivers aggressive low-end response without sacrificing highway manners, making it ideal for small-block and mid-displacement engines that need snappier launch characteristics. This is a complete, ready-to-install kit engineered for the GM 10-bolt—no guesswork, no missing components.
