Elite Gear

Elite ring and pinion sets use the latest engineering and manufacturing technology to produce OEM quality gears at an affordable price. All Elite gears are machined from premium 8620 alloy steel, then heat treated to the strictest standards for maximum strength and durability. Elite gears then go through an extensive lapping process to assure easy setup, excellent contact patterns, and quiet operation.  

Elite Powergrip Posi LSD

New clutch type posi differential provides aggressive yet smooth traction, perfect for street and performance applications. These units are full rebuild-able and use Eaton type internal components.

We recommend using standard 80/90wt (non-synthetic) oil with Posi additive. Use of Synthetic Oil will Void warranty.
