Product Description:
Hawks Motorsports is pleased to offer our clients the following 2010-2015 Camaro V8 3.73 Ring & Pinion Gear Set for the GM 8.6-inch/218mm IRS rear differential by Yukon Gear, part number YG GM8.6-373IRS.
A gear swap is one of those changes you can feel every time you roll into the throttle. The 3.73 ratio gives your Camaro a shorter, more aggressive final-drive ratio than taller gearing, helping the engine get into the powerband quicker and making the car feel more responsive when you put your foot in it. If you're building a street car, weekend bruiser, or a combination that needs the right rear-end ratio to match the rest of the drivetrain, getting the differential gears right matters.
This Yukon Gear high-performance ring and pinion set is designed for the GM 8.6-inch/218mm independent rear suspension differential used in applicable 2010-2015 Camaro applications. The set features an 8.60-inch ring gear diameter, 32-spline pinion, 10 ring gear bolt configuration, and a 3.73:1 gear ratio.
Yukon Gear designs its performance ring and pinion sets with high-grade steel construction and gear tooth surface finishing intended to help reduce friction and heat during demanding operation. Fitment is designed around the specified GM 8.6-inch IRS differential configuration.
