R5201 10-Bolt Alum Support Cover
R5210 GM 10-Bolt (8.2"/8.5") aluminum Ultra Support cover. The support cover features two premium grade load bolts; providing main cap support. The additional support of the case main caps dramatically reduces ring gear deflection, stabilizes gear back lash, and diminishes the chance of cap breakage and/or distortion. The Ultimate cover features two tapped holes, which will accept the optional LPW brace kit. Ultra-Pro covers are slightly lighter and are not machined to accept the brace kit. Each girdle is supplied with mounting bolts, filler plug and frain plug. Picture is for illustration purposes only and does not necessarily represent this product exactly.
