Scott's Hot Rods 4-Bar Rear Suspension Kits

Scott's Hot Rods 4-bar rear suspension kits have a simple design, but will greatly improve the ride quality and handling of your hot rod or custom. These truly equal length parallel 4-bars use a very long, perpendicular panhard bar to maximize efficiency and reduce lateral movement. Both user-friendly and fully adjustable, the kits also use their CNC-machined and tapped stainless steel rod ends with right-hand or left-hand thread, allowing you to adjust the pinion angle and setup without unbolting the link bars. And unlike a Triangulated 4-link system, the pinon angle does not change throughout the travel of the suspension. The kits are offered with coilovers or airbags. Your rear suspension is just as important as the front to the ride and handling of your car; install a Scott's Hot Rods 4-bar rear suspension kit and increase your driving pleasure. Additional notes and what's included: * CNC-machined 1 1/8 in. x 1/4 in. wall DOM tubing link and panhard bars (adjustable RH- and LH-thread) * Scott's utilize a bar as long as possible per vehicle application to ensure the least amount of lateral movement * CNC-machined stainless steel rod ends--RH- and LH-thread * FK Bearing heim joints--RH- and LH-thread * Aldan American single-adjustable coilovers or Firestone 9000 tapered air springs * Coilovers are the most popular for everyday cruisers * Airbag kits are for those who want to lay their vehicle on the ground * Upper shock crossmember is standard on all kits allowing you to determine final ride height when installing * Rear-end housing brackets * Front frame brackets * 5/8 in. Grade 8 hardware * Lifetime guarantee
