Yukon Gear High Performance Gear Set For Toyota V6 in a 5.29 Ratio

Yukon Gear Ring and Pinion Set for Toyota V6 Differential in 5.29 Ratio

The YG TV6-529-29 from Yukon Gear and Axle is a high-performance 5.29 ratio ring and pinion set built for the Toyota 8-inch V6 rear differential with a 29-spline pinion. This is one of the most aggressive ratios available for the Toyota V6 differential, making the YG TV6-529-29 the go-to choice for serious rock crawlers and off-road builds running 37-inch or larger tires. Coverage spans a wide range of Toyota trucks and SUVs from 1985 through 2019, including the 4Runner, Tacoma, Tundra, Pickup, T100, FJ Cruiser, and Lexus GX470. Yukon machines this gear set from premium steel alloy and inspects every set through two in-house quality control labs to verify tooth geometry, surface finish, and structural integrity. When maximum crawl ratio and torque multiplication are the priority, the YG TV6-529-29 delivers that capability in a direct-fit package for Toyota V6 8-inch housings.

Frequently Asked Questions

• Q: What differential does the YG TV6-529-29 fit?
  A: It fits the Toyota V6 8-inch rear differential in 4Runner, Tacoma, Tundra, Pickup, T100, FJ Cruiser, and Lexus GX470 from 1985 through 2019.
• Q: Is 5.29 a practical ratio for a street-driven truck?
  A: The YG TV6-529-29 is best suited for dedicated trail or rock crawl builds using 37-inch or larger tires. It provides outstanding low-range multiplication but results in higher RPM at highway speeds, so it is most popular on trucks used primarily off-road.
• Q: What is the spline count on this gear set?
  A: The YG TV6-529-29 uses a 29-spline pinion, correct for Toyota V6 8-inch carriers from 2003 onward.
• Q: Must I change the front differential ratio at the same time?
  A: Yes. In a 4WD vehicle, front and rear ratios must match. Install the correct 5.29 reverse-rotation gear set in the front differential simultaneously.
• Q: Does aftermarket gear installation affect my factory warranty under Magnuson-Moss?
  A: The Magnuson-Moss Warranty Act requires the dealer to prove the aftermarket part caused the failure before denying your warranty claim. Installing the YG TV6-529-29 does not automatically void your coverage.
• Q: What parts do I need alongside this gear set?
  A: You will need a Toyota V6 8-inch master install kit (bearings, seals, shims), gear marking compound, and a dial indicator setup tool.
• Q: What warranty is included with the YG TV6-529-29?
  A: Yukon provides a one-year warranty against manufacturing defects. The optional Y.E.S. plan extends this to lifetime coverage.
• Q: Is professional installation required?
  A: Yes. Setting up gear ratio changes in a differential requires precise pinion depth, backlash measurement, and contact pattern verification. Professional installation is strongly recommended to protect your investment.

Installation Instructions

1. Safely lift and support the vehicle. Drain the differential oil.
2. Remove driveshaft and rear axle shafts after marking orientation.
3. Pull the differential cover and clean the housing.
4. Record existing backlash and pinion bearing preload as a reference baseline.
5. Remove bearing caps, carrier, and old ring gear set.
6. Replace pinion bearings from the master install kit on the new YG TV6-529-29 pinion.
7. Shim pinion depth using a dial indicator to achieve correct tooth contact position per Yukon specification.
8. Press the new ring gear onto the carrier and torque ring gear bolts to specification in a cross pattern.
9. Install carrier, set preload, and adjust backlash to 0.006 to 0.010 inch.
10. Check contact pattern with marking compound; readjust pinion depth or backlash as needed.
11. Seal cover with RTV or gasket. Fill differential to capacity with the specified gear oil.
12. Reinstall axle shafts, driveshaft, and wheels. Torque fasteners to specification.
13. Follow the Yukon break-in procedure before hard off-road use.
