This exclusive design incorporates the latest technological advances in 4-link dimensioning, tuning and efficiency. By using, 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 Billet Urethane rod end. The 3/16" thick axle brackets have a 3" hole and feature a built-in lower wheelie-bar mount, a lower antiroll-bar mount and a double-shear, adjustable lower shock mount. Our billet-aluminum 6227 and 6247 lower shock mounts are adjustable in 5/8" increments for fine tuning ride height. Requires a 6214 shock-mount spacer kit. Our Eliminator II Pro Street 4-link uses the same geometry as our Standard Eliminator II 4-link. Instead of spherical bearing rod ends it uses billet steel rod ends with urethane bushing liners. In addition, one end of each link tube uses a urethane lined weld eye, which virtually eliminates the possibility of the rod end rattling loose, causing the link bar to fall off. The bars are direct threaded 1-1/4" x .156 wall tube to accommodate the huge 1"-shank billet rod ends. These rod ends are strong enough for blown street cars and offer plenty of flexibility for street driven vehicles. Eliminator II Pro Street 4-links are available with blue powder coating or chrome finish link bars. Like all Chassisworks 4-links, this version comes with a map of all intersect points and tuning instructions to simplify adjustments. Use track locater Part No. 6249 to center the rear end housing in the chassis. This 4-link fits all Chassisworks Eliminator II round tube subframes and chassis. BARE METAL FINISH
