QA1 Ultra Ride Coilover Shocks

QA1 Ultra Ride coilover shocks aren't called "The Best Ride in Rodding" for nothing. They're the ultimate in adjustable coilover shocks for street rods, hot rods, and Pro Street. Their bright-anodized, one-piece, machined-aluminum bodies provide great looks, but their strongest point is their 18-position adjustable damping with deflective-disc technology. You can easily select any of the 18 firmness positions--with the shocks in place on the vehicle--to get the control that you want. Ultra Rides have hard-chromed, centerless-ground 5/8 in. piston rods and double-lip wiper seals. Each is dyno-tested for consistency and comes with the appropriate zinc or chrome plated mounting hardware. The QA1 Ultra Ride coilover shocks also come remote ready, so they can be used with QA1's new wireless remote controller.
