Fully Built Toyota 8.4-inch Differentials
Fully built Toyota 8.4” 3rd members using new gears, seals, output flange, and bearings are ready to drop into your axle. Third members feature top-quality Trail-Creeper ring & pinion gears and your choice of lockers. Each unit is set up with solid pinion spacers for long gear life.
Price includes a $400 refundable core charge. Only usable 8.4” cores with a ratio of 3.58 or higher will be accepted (subject to inspection). 8.4” cores with a factory 3.31 gear ratio are not acceptable. Participants must ship used cores at their own expense (no COD shipments accepted). Contact our Sales team for questions and further instructions.
APPLICATION NOTES:
- Spools will be harder on axles than a selectable or automatic locker.
- For Toyota 8.4" solid rear axles only.
- Will not fit factory E-locker rear axles or 8" IFS front axles.
NOTE: Follow Ring & Pinion break-in instructions on the Instructions tab. Failure to do so will void the warranty. Super Finish™ 3rd members do not require any break-in period.
Ring and Pinion Break-In Procedure:
New 3rd members require a break-in period to prevent damage from overheating. Any overloading or overheating 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.
NOTE: Super Finish™ 3rd members do not require any break-in period.
