Revolution Differential Ring and Pinion

Revolution Gear & Axle Differential Ring and Pinion Sets

When it comes to re-gearing a differential, few names carry as much weight as Revolution Gear & Axle. With manufacturing roots stretching back to 1984, Revolution has spent decades perfecting the art of producing aftermarket differential ring and pinion gear sets that match — and in many cases surpass — OEM quality. Whether you're lifting your truck and running oversized tires, optimizing a tow rig for heavy loads, or building a dedicated off-road crawler, Revolution offers a ring and pinion solution engineered for the job.

Built From the Ground Up for Performance and Longevity

Every Revolution ring and pinion gear set starts with premium 8620 steel, a material known for its excellent case-hardening characteristics and exceptional strength under load. Each set is then precision heat treated to OEM specifications, ensuring the gear teeth can handle the stress of both daily driving and extreme use. What further sets Revolution apart is their lapping process: their gears are double — and in some cases triple — lapped for a flawless contact pattern, quieter operation, and extended service life.

Revolution also employs two distinct gear-cutting methodologies to suit different applications. Their 2-Cut Face Hobbed gears replicate the modern OEM manufacturing process, producing a gear profile that mirrors factory geometry for quiet, precise operation. For builds where installers prefer a more traditional tooth profile and easier setup adjustment, Revolution also offers 5-Cut (Face Milled) gear sets — a time-tested design favored in high-strength aftermarket applications. This dual-cut approach gives builders and installers the flexibility to choose the best option for their specific differential and driving needs.

Isotropic Superfinishing: Racing Technology for the Street

For enthusiasts who demand the absolute best in gear efficiency and longevity, Revolution offers ring and pinions treated with REM Isotropic Superfinishing (ISF) technology — a process long proven in professional motorsports. This finishing process micro-polishes gear tooth surfaces to reduce friction, lower operating temperatures, and further suppress gear whine. Revolution has incorporated this advanced finishing technique into their ring and pinion lineup for over a decade, giving street and off-road builders access to race-level refinement.

Wide Application Coverage

Revolution's differential ring and pinion catalog spans a broad range of popular axle platforms, including Dana 30, Dana 44, Dana 60, Dana 80, GM 8.5"/8.6" 10-Bolt, GM AAM 11.5" 14-Bolt, Ford 8.8", Ford 9", and Toyota applications ranging from the 7.5" to the 9.5" Land Cruiser axle. Gear ratios are offered across a wide numerical range — from mild street-friendly options up to aggressive crawl ratios — making it easy to dial in the perfect final drive for any tire size or use case.
