HD EcoSeal

HD Flange

Toyota 8.0" High Pinion Completely Assembled Differential equipped with a Grizzly Locker and all our exclusive Heavy Duty internal parts including our HD pinion EcoSeal!

Our Grizzly locking differentials are 100% ready to drop in. This "ratcheting" type locker is suitable for a daily driver yet capable for competition use. Compared to other automatic lockers, the Grizzly Locker has a softer engagement/disengagement thanks to a freely-rotating component design complete with an improved teeth engagement profile. Thanks to this, the Grizzly is fast becoming the number one choice in automatic lockers.

Every Differential we build comes with our EcoSeal Technology (more info) and the highest quality differential gears on the planet (why we trust and run Yukon Gears).

All 3rd members are assembled with trail proven Yukon R&P gears, new high quality Yukon setup kit with Japanese bearings, new Grizzly locker, our Heavy Duty EcoSeal pinion seal, our Heavy Duty pinion flange, and our Heavy Duty solid spacer kit where applicable. Please follow our R&P break in procedure to maximize the life of your new 3rd member.

NEW! We no longer charge labor when you purchase a fully built differential from us! (Saves $250!)
