Revolution Gear & Axle 16-24 Toyota Tacoma 8.75in Rear Axle 5.29 Ratio Ring & Pinion Set
The 5.29 ratio is for the Tacoma owner who has gone well past a mild tire upgrade: a built third-generation truck on tall tires, carrying armor, a drawer system or a rooftop camper, and spending time crawling. Revolution Gear & Axle T8.75-529 is a 5.29 ring and pinion for the 8.75 inch rear axle used under 2016-and-later Toyota Tacomas that came with the factory rear E-locker. It puts back the low-speed control and highway drivability that oversized tires take away.
In the 8.75 axle the 34-spline pinion drives the ring gear on the locker carrier, so the ratio between them multiplies every pound-foot the driveshaft delivers. A 5.29 is about 8 percent more multiplication than a 4.88. In practice that means a bit more engine speed on the highway in exchange for stronger pulls out of corners, less transmission hunting and slower, more controlled crawling in low range. Revolution builds this set from 8620 steel in Korea, with standard rotation and no carrier break, so it bolts to the factory locker carrier.
Find your factory ratio on the door-jamb axle code; Revolution's Tacoma axle article lists 07 as 3.909 and 06 as 4.30. Going from 3.909 to 5.29 is roughly 35 percent more gear, and from 4.30 it is about 23 percent, so compare that with how much taller your tires are than the originals. If 5.29 overshoots your tire size, the 4.88 rear set for the same axle is likely the better fit. The re-gear after bigger tires guide and how to find your axle code cover the process.
Only the 8.75 inch, 34-spline rear fits. On third-generation Tacomas that axle came with the rear E-locker; trucks with the open differential have an 8 inch, 29-spline rear and need different gears. Revolution lists this set for 2016-2023 Tacomas. Our listing title runs to 2024, but the 2024 model is a redesigned generation, so send us the VIN on a 2024 truck and we will check it before shipping. Four-wheel-drive trucks must change the front IFS differential to 5.29 as well; the Tacoma 5.29 gear package covers front and rear with Timken install kits in one order.
Deeper gears have a smaller pinion, so careful setup matters. Start from Revolution's Toyota 8.75 figures: 0.076 inch pinion shim as a baseline, 15-20 in-lb pinion bearing preload with new bearings, 0.006-0.010 inch backlash, and 70 ft-lb on ring gear bolts and bearing caps. Read the contact pattern on both the drive and coast sides before final torque. Fresh carrier bearings need to be pressed off and on; a carrier bearing puller set makes that job clean, and the Tacoma rear axle bearing puller kit handles the shafts. Fill with GL-5 gear oil, avoid towing and hard use during break-in and change the oil early, following our new ring and pinion break-in steps.

It depends on tire size. 5.29 turns the engine about 8 percent faster than 4.88 at the same speed. On tires that are much taller than stock it brings rpm back near the factory feel; on small tires it will feel buzzy.
No. Third-generation open-diff trucks use an 8 inch, 29-spline rear. This set fits only the 8.75 inch, 34-spline rear that came with the factory E-locker.
Yes. Revolution lists this set as no carrier break, so it mounts on the factory 8.75 carrier. Inspect the locker actuator and wiring while it is out.
Revolution lists 2016-2023 for this gear set. The 2024 is a new generation, so send us your VIN and we will confirm the axle first.
On a 4x4, yes. The front 8 inch IFS gears must match 5.29 or the truck will bind in four-wheel drive. The 5.29 gear package includes both sets and Timken install kits.
