Trail-Gear is proud to offer Trail-Creeper Ring & Pinion Gears. These are the very same gears that have won multiple championships on the W.E. Rock circuit and have proven themselves on some of the most grueling off-road courses in the world.
Our Trail-Creeper gears are made from tool-grade 8620 steel and heat-treated for maximum strength and wear resistance. The gear teeth are cut using Gleason CNC hobbing machines & cutters. Gleason gear-cutting technology produces an unprecedented level of accuracy and surface finish, which allows the gears to transmit more torque and improve fuel efficiency. The higher accuracy and surface finish also produces a quieter-running gear set, which means they’ll work great on the daily driver too.
If you’re looking for a Gear Set that’s easy on the wallet, but can handle whatever you throw at it, look no further, because Trail-Creepers are only available from Trail-Gear.
On Toyota trucks we recommend 4.88's for 33" tires and 5.29 for 35" and larger. Fits 79-85 4WD Toyota axle 8" ring gear, and most 86-95 rear axles only.
After installation drive lightly for 20-30 minutes and then allow the diff to cool for at least two hours.Ring & Pinion Break-In Procedure:
All new 3rd members require a break-in period to prevent damage from overheating. Any overloading or over-heating during this periods can cause the gear oil to break down resulting in ring & pinion failure.
- Avoid heavy throttle use during the first 500 miles.
- Do not tow a trailer during the first 500 miles.
- Change oil after 500 miles to remove any particles suspended in the oil.
This may seem unnecessary but it is very easy to damage the differential by loading it before the gear set is completely run in. New ring & pinion gears create excess heat when they are new. This excess heat can damage the heat treatment of the gears.
