Our popular Pro Street 4-link uses the same bracket geometry as our Battle Cruiser 4-link. Instead of spherical-bearing rod ends, it uses billet-steel rod ends with urethane bushing liners. In addition, one end of the link tube uses a urethane-lined weld eye, which virtually eliminates the possibility of the rod end rattling, causing the link bar to fall off. The bars are direct-thread, 1-1/4x.156" tube to accommodate the huge 1"-shank billet rod end. These rod ends are strong enough for blown street cars and offer plenty of flexibility for a street-driven vehicle. Pro Street 4-links are available with blue-powder coating or chrome-finish link bars. The 4-link front mount attaches under the rear frame rail, and is used for rear subframes and Eliminator I chassis. All hardware and billet rod ends are included.
