Description
Pro Mod Aluminum Housing
Strange’s Pro Mod Aluminum Housing are designed to accept an Ultra Case, HD Pro, or most heavy duty aftermarket cases. The housing has clearance to use 9”, 9 1/2”, and 10” development ring gears. The huge filler cap opening allows for inspection of the ring gear teeth without removing the center section. The drain plug features a magnet to retain harmful metallic particles. The upper wheelie bar mounts are cast directly into the main housing.
These housings are available in 16”, 17”, 18”, 19”, 20”, 21”, 22”, & 23” 4-Link centers. Chrome moly 4-Link mounts are not included but are available separately. The included floater hubs and drive plates can be ordered in 4 3/4”, 5”, or 5 1/2” bolt circle. Carbon brake housings come complete with 11” rotors, caliper mounts, calipers, and pads. Steel brake housings now have 11.5” stainless steel rotors, caliper mounts, calipers, and brake pads. Floater axles are in the Floater Kit section, while center sections choices are listed with the HD Pro, Ultra, & Billet Case assemblies.
Designed for the most brutal Drag Race applications.
Full Floaters place the weight of the vehicle on the housing leaving the axle itself free to deliver power to the wheel. The weight-bearing role is taken care of by a spindle that is attached to the tube of the housing. The spindle, hub and a set of bearings are responsible for supporting the weight of the vehicle.
