When we ran a full service chassis fab/turn-key hot rod shop a number of years ago, it was always useful to have threaded things around to weld into the frame for some kind of mount, etc.
Here’s a list of all our threaded things for your reference:
Parallel Four Link Axle Bracket Kit, PR
Axle Brackets, rear, for combination 4-link and lower coil-over mounts. Holes for 4-link are ½” diameter on 5-1/2″ centers. Coil-over mounting holes are backed with a 1” square block for extra support. The 3 coil-over holes are 5/8″ diameter on 1″ centers. The lower coil-over hole center is 4-1/2″ below the bottom of the axle tube. Made to fit 3″ or 3-1/4" diameter axle tubes, but easy to fit to 2-3/4″ axle tubes. If you have 2-5/8" or 2-13/16" tubes, please see the related items below for your brackets. We can design and supply custom brackets to your specs, too. Please get in touch.
All axle brackets are designed for 1-3/4" wide bushings.
Priced per pair.
