This exclusive design incorporates the latest technological advances in 4-link dimensioning, tuning and efficiency. By using 12-point, 1/2" bolts in the brackets, we moved the holes much closer together - providing much finer adjustment than was possible before. To accomplish this, we use a custom-made, 1/2"-bore with 3/4"-shank rod end 6276. The 3/16" thick mild steel brackets with 3" axle tube hole feature built-in lower wheelie-bar mount, lower antiroll-bar mount, and double-shear, adjustable lower shock mount. Our billet-aluminum lower shock mounts 6227 and 6247 are adjustable in 5/8" increments for fine tuning ride height. Our 4130 link tubes are a full 1-1/4"-OD, with weld-in adapters and hex adjusters. This design is considerably more resistant to bending than conventional 4-links with direct-thread, 1"-OD tubes. Like all Chassisworks 4-links, this version comes with a map of all intersect points and tuning instructions to simplify adjustments. Track locater 6275, or a wishbone (Part 6230 or 6280) can be used to center the rear end housing in the chassis. This 4-link can be used with all Chassisworks Eliminator II 3x2" subframes.
