SPC | Forged Adjustable Upper Control Arm Kit

Overview

The SPC Adjustable Upper Control Arm Kit is built for owners who prioritize strength, alignment control, and long-term serviceability over polished aesthetics. These arms are forged, not tubular or billet, resulting in a design that emphasizes durability and real-world performance where it matters most.

Unlike cosmetic-focused control arms, SPC arms are engineered as a function-first solution for lifted vehicles. The forged construction provides exceptional strength and fatigue resistance, making them well-suited for daily driving, heavy loads, and repeated off-road use. The industrial finish reflects their purpose: they’re designed to work hard, not win beauty contests.

SPC’s fully adjustable alignment system allows for precise correction of camber and caster after a lift, helping restore proper steering feel, straight-line stability, and tire wear. Just as importantly, these control arms are fully rebuildable, meaning worn components can be serviced rather than replaced — a major advantage for long-term ownership and hard use.

This is a proven design trusted across multiple Toyota platforms for years, and it remains one of the most effective alignment solutions available for the LC250 and GX550. If you care more about capability and reliability than show-car looks, these are hard to beat.
