Details:

Helical gear differential gives positive traction without the noise of a full locker. Stronger due to its larger bearings, our Dayton pinion support also uses the spacer-and-shim setup maintain critical depth settings under high load, unlike traditional crush sleeves which often compress further, take out your reload and lead failure. An oil fill plug is included. Our gears use cold-rolled 8620 steel, known for its long-wear and durability.

The pinion gear is connected to our new, forged steel Ford short, 1310-type yoke. Precision assembled for proper ring gear teeth pattern: getting a proper pattern on the ring gear teeth is crucial. We bring this combination of precision assembly and quality components to you at a price that can't be beat. Large bearing Dayton pinion supports for strength and reliability.

Units include a Vito pinion seal providing long lasting oil and chemical resistance. While under normal conditions the helical-gear performs like an open differential, when required differential automatically transfers torque to wheel with highest traction. Tapered steel roller bearings minimize friction, better handle thrust loads and increase load carrying capacity. The improvements continue with rugged billet steel adjuster nuts and heavy-duty keepers to ensure your ring gear settings are maintained.

Vito pinion seal, resistant to chemicals and high temperatures. We discussed my build and he helped me choose the gearing that would work best for. Our time-proven, step-by-step process ensures the correct backlash, reload, and proper amount of pinion shims to ensure pattern on ring gear teeth. Hand-assembled by our trained technicians for an unbeatable combination of quality and value.

Tough, nodular iron section: our Ford 9 inch third member section carrier starts with a new casting over 4 lbs. Since reload is already set, simply torque the pinion nut to 160 ft./lbs. No other yoke size options are available. And you re good to go.

Fastest delivery ever hundred percent satisfaction Speedway: rated by slick. Smooth power transfer is unnoticed by the driver. A great deal. Precision assembly for the correct backlash, reload, and proper amount of pinion shims to ensure pattern on ring gear teeth.

The helical-gear design gives quiet operation, with no ing when disengaging for corners. Extra ribbing reinforces the case and rearmost pinion support pilot bearing. Our third-member units are shipped in a durable, reusable poly storage case, perfect for keeping multiple gear sets stored and ready the track. With solid bearing spacers and the proper shims, we eliminate this problem make setting reload easy repeatable during installation, service gear changes.

A carrier-to-housing gasket is available separately. Spacer and shim setup maintains critical pinion depth settings easier to service than traditional crush sleeves. Headquarters. Yes, I recommend this product.

Includes form fitted, reusable red poly storage case. Lock-style pinion nut with pre-applied lactate. It was a great experience.
