LPW ULTIMATE support covers are available for 22 applications and are the only covers which allow the addition of LPW's axle-tube brace. Most ULTIMATE covers measure approximately 4-1/8" tall. Low profile ULTIMATE covers offer improved chassis clearance by measuring only 3-5/8" tall.

ULTIMATE support covers have increased clearance allowing for low gear ratios and additional fluid capacity. ULTIMATE support covers are engineered to strengthen the rear housing from unwanted case distortion and gear deflection.

All LPW support covers incorporate 2 adjustable load bolts that support and prevent the main caps from movement and possible breakage. LPW's load bolts have been certified to be more than 40% stronger than any other brand's load bolt. This makes LPW support covers the strongest on the market.

Upgrade your old main cap bolts with the LPW main cap stud kit. LPW stud kits are available for all popular applications and use high quality ARP fasteners.

Third Party Analysis: Why is LPW on top of the competition?

Here's the certified facts reported by Henry J. Yeager Laboratories:
LPW stands behind their claim that LPW Covers are the strongest support cover with documented facts. Recent tests of a competitor's 12 bolt cover versus the LPW Ultimate 12 bolt cover found the competitor's load bolt started to compress at only 10, 400 lbs of pressure. When increased to 14, 500 lbs the competition's stud actually bent and cracked. The LPW load bolt did not show any signs of compression or failure with equal pressure loads applied. It was also discovered that while the LPW's load bolt hole is fully threaded. The competition's is not.
