Internal Nest Kit

We use high-quality materials to ensure long-lasting products inside our internal nest kits. Each internal nest kit includes two side gears, two pinion gears, cross pin shafts, and spider gear thrust washers.

Full Spool

Full Spool

If you find that you are doing a lot of work to repair off-road, racing, or hot rod damage, the full spool is great for traction differential. High-quality materials provide high strength and durability providing 100% traction at all times.

Mini Spools

Mini Spool

The difference between a full spool and a mini spool is strength. Mini spools will drive like a full spool but are not quite as strong as a full spool. This means they do not support the ring gear. A mini spool replaces the spider gears and locks the left and right axle shafts together.

Differential Covers

Crush Sleeve

Crush Sleeve

Clutch Packs

Clutch Packs

The clutch plates we offer are thicker than OE clutch plates. When rebuilding this allows you to skim cut adjacent surfaces. Most often, a thin, fragile, single-sided OE clutch is the cause of clutch burnup. Distorted clutches take clearance out of spec, making burn up inevitable.
