SPL Parts is a performance suspension manufacturer that designs and tests their products all in-house here in the USA. Additionally, all materials used are sourced from American suppliers to ensure consistently high quality products. SPL Parts products are all constructed using chromoly seamless straight tubing, DOM mandrel bent tubing, and 6061 and 2024 aluminum for high strength and quality. All TIG welding and CNC machining is also done locally by professional welders and machine shops to meet exact quality standards and tolerance specifications. For anything from racing to street driven needs, SPL Parts offer an amazing line of premium quality products that are perfect to get your car back in spec.
These SPL front lower control arms open up a wide range of adjustment for roll center, camber, and track width adjustment and allow for full articulation with the correct ball joint angle. Instead of using traditional jam nuts, the main arm is slotted to allow the use of pinch bolts and SPL rotating clamps on their exclusive adjuster, making it easier to lock in track width and camber specifications.
