What is included in this Yukon re-gear kit?

This kit includes a high-quality ring and pinion gear set with a 4.11 ratio, all the necessary bearings (including 2.25" AK 1563 axle bearings), and all required installation hardware for your GM 8.875" 12-bolt axle.

What kind of acceleration improvement can I expect with a 4.11 gear ratio?

A 4.11 gear ratio is more aggressive than stock ratios, meaning your engine will reach higher RPMs in each gear. This typically results in improved launching ability and quicker acceleration from a standstill, often described as a 'shot out of a cannon' feeling.

Does this kit come with installation instructions?

While this kit contains all the parts needed for a re-gear, it's recommended to refer to the manufacturer's detailed installation instructions. Re-gearing a differential is a complex process that requires precision and specific tools.
