Trailing Arm | URC Trailing Arms | Double Shock Mount Set-Up | by: RuffStuff

Ultimate Rock Crawling Trailing Arms / heavy duty trailing arms specifically designed for the rocks! They have been tested and tortured in Ultra4 racing's 4400 class so you know they can handle anything you throw at them! They've been designed the RuffStuff way of STRENGTH, QUALITY, VALUE!

Easy weld-it-yourself kit for the competent welder or completely welded and ready to install, they are narrow-profile, easily customized, and tough as nails. These come with a Lifetime Warranty when welded by RuffStuff Specialties, All competitive racing applications INCLUDED!! Our URC Trailing Arms measure 48" eye-to-eye, with a 2" x .25" wall DOM main tube, 1/4" thick 1-piece main plate bent 3 times for maximum strength, minimal welding and warpage, and easy assembly.

Shocks mount BELOW the line between the bushing and heim (Unlike some competitors!) which prevents the trailing arm from trying to rotate when the shocks push down on it because the shocks "hang" below the center line. This Extends bushing life because the bushings and shocks are pushing to keep the arm straight together rather than the shocks fighting the bushings and trying to rotate the arm. These arms could be customized to use heims and uniballs instead of bushings (even without wobble stops). Dual drain slots allow for easy cleaning and helps extend life of shock eyelet bearings.


  • Will not cause bent shock shafts should a bushing wear out or fail.
  • Second hole can be used as a strong and simple limiting strap mount if bypasses aren't used.
  • 3" wide polyurethane bushings at the frame side and our famous 1-1/4" heim joints on the axle side.
