KTA287

Lower Control Arm and Tension Strut Arm Kit

Whiteline KTA287 for the BMW M2, M3, and M4 Series is a set of four complete arms designed to resolve common front-end issues. Due to the high performance of many BMW models, the original rubber tension strut arm bushings are subjected to significant load and typically have a limited service life. Additionally, many owners lower their BMW using lowering springs or coilovers, which can introduce front-end geometry issues that require correction. For ease of fitment, these alloy tension arms come complete with sealed ball joint ends and adjustable synthetic elastomer bushings. These allow for ±0.5 degrees of caster adjustment, improving straight-line stability, enhancing steering feel, and increasing front-end grip on corner entry. The front control arms also feature sealed inner bearings to deliver superior precision, durability, and reduced deflection under load. High-strength ball joints are included with the arms, making this a fit-and-forget solution compared to the shorter service life of lower-quality aftermarket alternatives.
