Auburn Gear Grip-N-Loc™ Differentials These Auburn Gear Grip-N-Loc limited-slip differentials feature an exclusive cone and cup clutch design that transfers up to fi ve times the torque of the low-traction wheel to the high-traction wheel. That means improved grip on the street, track, or trail while still maintaining good cornering performance. Plus, they’re built with hardened steel gears and a nodular ductile iron case that’s up to 50% stronger than your stock differential. Each comes with a 6 oz. bottle of friction additive, detailed instructions, and a manufacturer’s 2-year limited warranty. Made in the USA.

Operation is fully automatic—engine power is directed to the wheels with the most traction, even if one wheel is off the ground in some extreme maneuver. Lock-Right keeps the axles locked for straight-line travel, then allows the gears to overrun each other when the wheels need to differentiate through a turn. Available in sizes to fi t virtually any application—ideal for vehicles used primarily under severe driving conditions. Yukon Gear & Axle Grizzly Locker® Your performance engine is only as strong as your differential—so step up to a tough-as-nails Yukon Grizzly Locker! Each mechanical positive- locking differential has a rugged 8620 triple alloy steel case, hand-fi tted forged internals, and large radius teeth for greater strength over back-cut counterparts. It all adds up to fast engagement and maximum traction during demanding operating conditions. Grizzly Lockers also provide 100% power to both tires while allowing disengagement during turns. Backed by a manufacturer’s 1-year warranty.

Yukon Gear & Axle Dura Grip Differentials Make sure your power gets planted properly with a Dura Grip positraction differential from Yukon Gear & Axle. Positraction carriers give you the performance and confi dence you need to dominate the trail, street, or strip. The nodular iron cases are stuffed with heavy-duty 4320 chromoly spider gears and a four-spring Raybestos® composite clutch for longevity and reduced chatter. They’re completely rebuildable for easy repairs, modifi cations, or upgrades without having to buy a new unit.
