LONGACRE ECONOMY SIDESLIDER™ SINGLE WITH 3 SPACERS LONGACRE ECONOMY SIDESLIDER™ SINGLE WITH 3 SPACERS LONGACRE SideSlider™ Slip Plate / RollersFor Bind-Free SetupsWhen you lift your car to put on scales the front wheels camber in at the bottom. As you let it down the wheels must be allowed to freely camber back out or there will be a small residual bind in the chassis. This will make your wheel weights (and your setups) less than perfect. To avoid this the front wheels must be able to easily move sideways. With SideSlider™your front wheels can move sideways effortlessly to relieve any camber-induced bind. This will assure you the most accurate, consistent setups possible. Rollers are made from a tough, low friction polymerInstall under Left Front wheel (it has the most camber change)3 spacers are included to re-level your setupUse on any smooth floor surface2 SideSlider™ systems are available for independent rear suspensions (PN 72872)SideSlider™ dimensions - 15-1/4" wide x 18" long x 1/2" tallSpacer dimensions - 15" x 15" x 1/2"
