Description
Assembled 3rd Members All new parts, no used housings or internal parts. Ready to drop into your axle. Third members feature top quality ring, pinion gears, and lockers. V6 units feature larger OEM style V6 gear sets with longer pinion gear.
Each unit is setup with solid pinion spacers for long gear life. Triple drilled flanges included covers common driveshaft patterns. High Pinion units should only be used in front axle applications. Use in the rear axle will lead to ring and pinion failure. Spool lockers should only be used in rear applications. Spools will be harder on axles then a selectable or automatic locker.
For Toyota 8.0 Inch solid axles only. Will not fit 7.5 Inch IFS front axles. Fully built 3rd members will not fit stock Tacoma or T100 axles.
Now available with Yukon Grizzly and Zip Lockers!

Application Notes: High Pinion units should only be used in front axle applications. Use in the rear axle will lead to ring and pinion failure. Spool lockers should only be used in rear applications. Spools will be harder on axles then a selectable or automatic locker.
Note: Follow Ring & Pinion break-in instructions below. Failure to do so will void warranty.
Note: V6 Housings do not have an ABS sensor port and are not compatible with the factory ABS system.
Ring and Pinion Break-In Procedure:
New 3rd members require a break-in period to prevent damage from overheating. Any overloading or over-heating during this period can cause the gear oil to break down resulting in ring and pinion failure.
- After installation, drive lightly for 20-30 minutes and then allow the differential to cool for at least two hours
- 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 and pinion gears create excess heat when they are new. This excess heat can damage the heat treatment of the gears.
