Strut Extension - Most late-model 1/2-ton trucks and SUVs utilize a coilover strut for the front suspension; the shock and coil spring are together in one compact unit. A simple strut extension is utilized on these applications. This involves adding an application-specific spacer to the top of the factory strut assembly. This method does not preload the factory coil spring (which firms-up ride quality) or over-extend the factory shock. No modifications to factory-installed parts are required and no time-consuming disassembly of the factory strut is needed. The strut extension is easily removable should the vehicle need to be returned to stock, and some applications include modified extension stops if needed. Level-It strut extensions are the most cost-effective and efficient way to level the stance of your late-model truck.
