Vehicle Fitment

• 1997-2006 Jeep Wrangler TJ - Dana 30 front axle
• 2000-2001 Jeep Cherokee XJ - Dana 30 front axle
• 1997-1998 Jeep Grand Cherokee ZJ - Dana 30 front axle
• 1999-2004 Jeep Grand Cherokee WJ - Dana 30 front axle

Fitment Notes

• Sold as a complete master install kit - all components listed below are included; no additional bearings, seals, or hardware are needed for a standard ring and pinion installation
• 35-2031 is specific to the 1997 and newer Dana 30 front axle - this generation uses different bearing specifications than the earlier CJ/YJ/XJ Dana 30 (1972-1996), which is covered by a separate Revolution Gear kit; verify your specific axle year before ordering
• Bearing type: Timken - Revolution Gear master kits use Timken bearings as standard; part numbers ending in "-K" in the Revolution Gear lineup indicate Koyo bearings; the 35-2031 does not carry a "-K" suffix and therefore uses Timken bearings. The Koyo bearing version of this kit is sold separately
• This kit fits the Dana 30 front axle only - for the rear differential (Dana 35), a separate master install kit is required
• For 2007+ Jeep Wrangler JK and 2018+ JL Dana 30 front axles, different kits apply - verify chassis generation before ordering

Features

• Complete master install kit with Timken bearings - everything needed to properly re-bearing the Dana 30 front differential and install a new ring and pinion gear set, sourced from trusted name-brand suppliers including Timken for bearings and National for seals
• Timken bearings - the gold standard for differential rebuilds, providing precise manufacturing tolerances, excellent load capacity, and long service life; critical for achieving proper backlash and preload settings during differential setup
• Comprehensive hardware package - includes ring gear bolts, pinion nut, crush sleeve, and all required shim sets so the installer has everything needed without additional sourcing
• Gear marking compound and Loctite included - professional setup consumables allow the installer to verify proper tooth contact pattern and secure ring gear bolts to specification
• Differential cover gasket or RTV sealant included - cover sealing materials provided for a complete, leak-free installation
• Designed for both daily driver rebuilds and off-road performance applications - meets the demands of regearing, trail use, and hard off-road operation in TJ Wrangler, Cherokee XJ, and Grand Cherokee ZJ/WJ applications
• 1-year limited warranty against manufacturing defects

Product Description

The Revolution Gear 35-2031 is the Timken bearing master install kit for the Dana 30 front axle used in the 1997-2006 Jeep Wrangler TJ, 2000-2001 Cherokee XJ, 1997-1998 Grand Cherokee ZJ, and 1999-2004 Grand Cherokee WJ - a comprehensive, all-in-one package containing every component needed to properly rebuild the Dana 30 front differential and install a new ring and pinion gear set. The kit is built around Timken bearings and National seals, providing the precision fit and long-term durability required for confident daily driving and trail use.

The 35-2031 covers the 1997+ generation of the Dana 30, which uses different bearing specifications than the earlier CJ/YJ/XJ Dana 30 (1972-1996) - making it critical to select the correct kit for your specific axle year. In addition to Timken bearings and National seals, the kit includes ring gear bolts, pinion nut, crush sleeve, all required shim sets, differential cover sealing materials, gear marking compound, and Loctite - everything a professional or advanced DIY installer needs for a proper differential rebuild without sourcing components separately. A Koyo bearing version of this kit is also available for builders who prefer that bearing brand. Backed by Revolution Gear's 1-year limited warranty against manufacturing defects.
