When upgrading your Toyota truck for larger tires, heavy loads, or off-road performance, stock gearing can fall short. The Yukon 4.88 ring and pinion set solves this by restoring low-end torque and drivability. Whether you're climbing, towing, or daily driving, this gear set is engineered to deliver strength and precision.
Designed to fit Toyota 8.4" rear axles in Tacoma, T100, Sequoia, and early Tundra models without a factory locking differential, it features an 8.125-inch ring gear diameter, 30 spline pinion, and 12 ring gear bolts. Manufactured with advanced heat-treating and strict quality standards, this set delivers performance you can rely on.
If you're looking for better crawl ratios, more responsive power delivery, or improved fuel economy with larger tires, this is the gear upgrade you need.
