Revolution Gear & Axle 10-23 Toyota 4Runner 8.2in 4.88 Ratio Ring & Pinion Set. A direct-fit ring and pinion engineered for 2010–2023 Toyota 4Runner applications to restore proper gearing when changing tire size or recovering driveline performance.

This ring and pinion set from Revolution Gear & Axle delivers the specified 4.88 final drive ratio for the 8.2in carrier used in many 4Runner differentials. It is intended for owners who need a reliable, vehicle-specific gearing solution without guessing compatibility. The gear set provides the correct ratio for those fitting larger tires or adjusting for lift height, helping the engine run closer to its intended rpm range under load.

Installation requires correct setup of backlash, preload, and carrier shimming; professional installation is recommended if you are not experienced with differential gear work. We offer installation and basic customization services at our locations and can advise on compatibility with lockers, limited-slip units, and axle assemblies.

If you have questions or want help confirming fitment, call us directly: 512-982-9393 (TX) or 562-981-6800 (CA). We have two locations in Austin, Texas and the Los Angeles, California area where we offer installation and customization services. If you are considering purchasing multiple items, contact us for possible shipping discounts. We install on premises at both locations.
