Product description
The Rotary Square Guide Axle Kit is a specialized repair package for the rolling jacks and bridges used on 4-post lifts. This kit replaces the old-style end section axles that ensure the rolling jack travels smoothly along the square guide rails of the lift runways. It includes precision-machined steel wheels, axles, springs, and bushings required to rebuild one corner of the rolling jack. Worn axles or flat-spotted wheels can cause the rolling jack to bind or become difficult to move, hindering shop productivity. This SVI kit provides a heavy-duty, direct-fit solution that restores the easy, gliding motion of your bridge jacks. Regular maintenance of these guide assemblies ensures a safe and efficient workflow during brake, suspension, and wheel service.
