RJ Pro Series Housing Brackets were designed for high horsepowered cars.
These ¼” thick 4130 brackets are available for 3, 3¼, and 3½” axle tubes. This bracket has proven itself on RJ built cars for years!
Close tolerance holes for the ½” NAS bolts provide considerably less bolt movement than other systems. The brackets also feature a hole spacing of .800” instead of the normal 1” spacing to allow for a greater range of adjustment.
When mocking up and welding together brackets you should use grade 8 bolts. After all the welding is done you should ream the holes to correct size. DO NOT USE A DRILL BIT!
We recommend using NAS bolts.
