Delrin has the highest tensile strength of any thermoplastic and is the best material available for heavy duty applications, while still being light-weight and resistant to typical corrosion associated with off-roading. Most aftermarket kits are flimsy welded steel, or cheap injection molded plastic. Choosing premium material parts should always be your #1 choice. We guarantee our High-Crystalline Performance Delrin Spacers will NOT compress under load. We back this statement with our Lifetime Warranty Policy.Note:?*Will Not Fit Vehicles With Welded Bump Stops
