What is the purpose of a 4.88 gear ratio?

A 4.88 gear ratio is typically used when you've installed larger than stock tires on your vehicle. It changes the final drive ratio, allowing your engine to spin at a higher RPM for a given road speed, which helps restore lost acceleration and towing power.

What does 'offset' mean in the fitment description?

The 'offset' in the D70 4.88 R&P 5/8" OFFSET description refers to the pinion offset of the Dana 70 axle housing. This specific gear set is designed for those Dana 70 differentials that have an offset pinion, which is common in many truck applications.

Does this gear set come with installation hardware?

This product listing is for the ring and pinion gear set only. Installation typically requires additional components such as bearings, seals, and shims, which are usually sold separately. Always refer to the manufacturer's installation instructions for a complete parts list.
