Yukon Ring & Pinion Gear Kit Front & Rear for Toyota 8.4/8IFS Diff (w/o Factory Locker) 4.88 Ratio

When you're ready to change your Toyota Tacoma's gear ratio, this Yukon Ring & Pinion Gear Kit package is what you'll need. It's designed for the front 8.0-inch IFS clamshell differential and the rear 8.4-inch differential, specifically for models without a factory locker and that use a 3-series front carrier case (typically for 3.73 and numerically lower gears). This kit comes with both the front and rear ring and pinion gears, along with all the necessary installation hardware to get the job done right.

Yukon Gear & Axle puts together these kits with a 4.88 gear ratio, which is a popular choice for Tacomas that have been lifted or fitted with larger tires. Changing your gear ratio helps your engine and transmission work more efficiently with the new tire size, improving acceleration and towing performance. The kit includes essential small parts like ring gear bolts, crush sleeves, pinion nuts and washers, and thrust washers, so you have most of what you need for the installation. The rear ring gear measures 8.125 inches in diameter, and the pinion is 30-spline.

This is a comprehensive package for upgrading your drivetrain. It's important to note that this kit is designed for the 8.0-inch IFS front differential and the 8.4-inch rear differential. If your Tacoma has a factory locker, you'll need a different kit. For the front differential, this kit fits cases designed for 3.73 and numerically lower gear ratios.
