Powerdown Sleeve 16 Id X 20 Od X 57 WPowerdown steel crush tubes and washers are precision-dimensioned components that form the correct clamping interface for shock absorber bush installations. The crush tube sits inside the bush and limits how far the mounting bolt can compress the bush - preventing both over-clamping (which collapses and destroys the bush) and under-clamping (which allows the bush to walk out of the eye ring under load).Using the correct crush tube is not optional. Incorrect clamping force is one of the most common causes of premature shock absorber bush failure and shock absorber noise in heavy vehicles - yet it is one of the cheapest and simplest problems to prevent by using the correct hardware at installation. Precision-dimensioned to the correct ID, OD and length for specific shock absorber eye ring and pin combinations Limits bolt clamping force to the correct value - prevents bush compression failure and walkout Multiple ID/OD/length combinations available to suit all major shock absorber mounting configurations Essential for correct bush installation - incorrect clamping is a leading cause of premature bush failure Steel construction maintains correct dimensions under clamping loads Part number: CT721 | Vendor: Powerdown | Australian designed for heavy commercial vehicles | Technical enquiries: 02 4949 0000 | [email protected]
