Strange offers several options to improve the look and strength of GM, Mopar and Ford rears. The LPW support covers feature two premium grade load bolts; providing main cap support. The additional support of the main caps dramatically reduces ring gear deflection, stabilizes backlash, and diminishes the chance of cap breakage or distortion. The Strange billet aluminum caps are lighter and far superior in strength than the OEM caps. The billet aluminum caps are manufactured from heat treated 2024-T351 aluminum and provide exceptional durability at minimal weight.
