Supra / SC300 Front Lower Control Arms

Buck Performance Extreme Front Lower Control Arms

The Problem:
Front Lower Control Arms (LCAs) on Toyota Supra and Lexus SC models have long been plagued by a common issue—outer ball joint failures. When these ball joints fail, otherwise functional arms must be discarded. With OE stock becoming scarce and support potentially discontinued, a durable and serviceable solution is essential.

The Solution:
Buck Performance Extreme LCAs resolve this issue with serviceable outer ball joints and an innovative design that delivers superior adjustability and durability. With a camber adjustment range of (EACH CAR IS DIFFERENT) ~±4 degrees, these LCAs offer flexibility and enhanced performance for demanding applications.

  • FK Extreme HD PTFE-lined rod ends and bearings for a precise interface and long-lasting performance.

• High-Quality Materials:

  • Alloy Boxed Steel construction for unmatched strength, proudly made in the USA.
  • Billet 6061 aluminum spacers and inner heim spacers for added durability.
