SPL's suspension products are designed to provide adjustability and increased performance for custom alignment needs, from full racing to high-performance street applications. The highest quality construction and innovative features are the reasons why SPL's products are not only chosen by top race teams but also by consumers demanding the best alignment products for their high-performance street cars.

To ensure quality, SPL sources materials from the USA with certification. CNC machining is performed by local machine shops with years of high-tech machining experience to meet SPL's exacting tolerances. Local professional welders with years of experience perform TIG welding to ensure the highest quality welds for maximum strength. All parts are hand fitted to ensure good fit and smooth threading, with anti-seize and 3M internal panel coating applied where necessary for protection.

SPL conducts in-house research and development, which allows them to provide total support to their customers since they design and use the products themselves. The spherical bearings with Teflon liners are self-cleaning and self-lubricating, providing high performance and long life. The innovative adjuster design provides quicker alignments and proper bearing centering, with tight thread tolerances for precision.

SPL's suspension products are made with pride in the USA by skilled machinists and welders, using quality materials and finishes, innovative designs, and R&D.
