Fix sun gear shell problems with BRAINS, not just brawn.

Stronger, Durable Shell

Shell Breakage

Stripped Splines

The SmartShell avoids the weight found in traditional, heavy-duty aftermarket shells. A unique combination of improved design and manufacturing delivers a super strength shell that's only slightly bulkier than OE.

Unbeatable Bearing Protection

Damage to the Small Captured Bearing

Residual Planetary Damage

To prevent thrust loads from overwhelming the captured planetary bearing, the SmartShell features a larger bearing and custom roller clutch race. These parts re-route thrust loads through the carrier, completely bypassing the delicate bearing.
