Make servicing off-vehicle strut springs safer and hassle-free with the Powerbuilt Strut Spring Compressor kit. Designed with safety and easy removal in mind, the heavy-duty forged spring hooks have safety bars on the spring hooks to help reduce the chance of slippage. The screws are heat treated for durability and prevent misalignment and jamming up during spring removal or installation. Struts come in a blow-molded hard case with professionally written instructions and usage photos. Powerbuilt Strut Spring Compressor meets or exceeds ANSI standards.
