One look and it's clear; the TMRC Billet Housing is an incredible piece of automotive engineering. Machined from 6061-T6 hardened aluminum alloy, the Billet Housing demonstrates remarkable strength over traditional cast housings. Rib and gusset areas were also engineered to improve strength and reliability over conventional designs. 

Additionally, the Billet Housing features an expanded fill cap and requires no third member gasket due the placement of an o-ring in its face. TMRC knows that every car is different and is able to offer the Billet Housing with preset and custom four link spreads instead of using the "one size fits all" approach.
