What is the purpose of a 3.42 gear ratio?

A 3.42 gear ratio is often chosen to improve acceleration and towing capability compared to taller (numerically lower) ratios, or to compensate for the increased tire size and bring the engine's RPM back into its optimal range.

Does this gear set come with installation hardware?

This product includes the ring and pinion gears. It is recommended to purchase new bearings, seals, and installation kits separately, as these are typically not included with the gear set itself.

What is the Yukon Y.E.S. Plan?

The Y.E.S. Plan is a lifetime, comprehensive protection plan offered by Yukon Gear & Axle that covers your gear set for as long as you own the vehicle, providing peace of mind against manufacturing defects.
