Extreme Pro Series Wishbone Kit

Wishbones are the preferred way to mount and keep the rear end housing in the center of the car. Wishbones offer more strength and less flexibility than a diagonal link.

Our Extreme Pro Series Wishbone is the ultimate wishbone designed specifically to handle high horsepower cars such as Pro Modified and Pro Stock applications. This is the same kit used in all Pro cars built at RJ Race Cars.

This kit features a greasable 1" O.D. 4130 slide tube with machined wrench flats, 4130 tubing and 4130 rod ends with 1/8” wide x 3/8" I.D. step bushings for the front mount rod ends. Complete with NAS bolts, 12-point ARP nuts, and weld-on rear end housing and front chassis mounts. Max width 21-1/2”. Welding required.

1-1/4" SLIDE TUBE OPTION:

This is the same kit as our original RJ-201201-EX Extreme Pro Series Wishbone Kit, but this kit features an even larger and stronger billet 4130 1-1/4" OD slide tube option. This is a 25% increase in slide tube diameter over our standard 1" billet 4130 Pro Series slide tube. The upgrade doesn't stop there, as this kit also features a larger 4130 heat treated 3/4"-16 rod end (the same spec that is used in our 4-Link bars) for the center slide tube to provide extra strength over the standard 5/8" rod end.
