Once you hit on a magic formula with rear end housings, there isn’t necessarily a lot to change year to year, and the team at Chassis Engineering believe they have that formula in their fabricated 9-inch race housing.

One of two custom, race-bred housings on display in the Chassis Engineering booth here at PRI, the 9-inch features 3.5-inch tubes with 1/4-inch wall tube thickness in chrome-moly form and 3-inch, 1/4-inch wall tubes in mild steel. Every element of the housing bell is laser-cut and hand-welded, and Chassis Engineering custom builds each and every housing to order based on a spec sheet provided to and completed by the customers — this dictates housing end length and housing end styles, width and placement of the brackets, and so on.

The housings are internally braced and feature a custom back brace for structural support. The parts are all hand-fit, built from the ground-up in what Chassis Engineerings’ Curt Perry calls a “labor-intensive piece.” Boxing strips are welded on the brackets front and rear to add more rigidity to the brackets themselves, and if necessary for width or strength, doublers are added either inside or outside the bracket holes. Chassis Engineering can also add or modify adjustable shock mount brackets per the customers’ demands, as well.
