Revolution Gear & Axle Master Install Kit for Jeep (2018-26) Wrangler JL, Dana 30 (186MM) Front Axle

This Revolution Gear & Axle master install kit supplies the bearings and setup hardware to install a ring and pinion in the 186MM Dana 30 front axle of 2018-26 Jeep Wrangler JL non-Rubicon models. It is the install kit, not the gears.

The kit uses Timken carrier and pinion bearings and includes a crush sleeve, carrier and pinion shims, a pinion seal, ring gear bolts, and cover gasket or silicone – a comprehensive bill of material for overhauling the JL front Dana 30.

It is the right kit for owners regearing a JL front Dana 30, typically to match a deeper rear ratio after a tire upgrade or to rebuild worn bearings during a gear swap.

Gears are sold separately, so pick a Revolution JL Dana 30 186MM ring and pinion to go with it. Note that axle seals are not included on this kit; it covers the differential rebuild. Have an experienced installer set pinion depth, backlash and preload.

A matched Revolution master install kit removes the guesswork of sourcing the correct front-axle setup parts and supports a clean, reliable install.
