J&M Products Adjustable Weight Jack Rear Lower Control Arms (23858-R - Red Powder Coat) - 1979-1998 Ford Mustang
Take total control of your 1979-1998 Ford Mustang's rear suspension geometry with J&M Products adjustable weight jack lower control arms. Engineered for both serious street performance and track-day use, these arms feature a built-in spring perch weight jack that allows for precise on-car ride height adjustments and corner-weight tuning. By replacing soft factory components with robust 2-inch round steel tubing and a performance-oriented 3-piece Poly-Ball bushing system, these arms eliminate unwanted flex and binding, resulting in consistent launches, improved traction, and superior cornering predictability.
Manufactured in the USA, these weight jack control arms utilize CNC laser-cut, pulse-welded construction to ensure structural durability under the most demanding conditions. The proprietary 3-piece Poly-Ball bushings—featuring a hard inner synthetic elastomer ball and soft outer cups—provide the rigidity necessary for high-performance handling while maintaining the articulation required to prevent suspension bind during body roll. These direct bolt-on replacements come equipped with factory-correct sway bar mounts and are finished in a durable red powder coat for long-term corrosion resistance, making them the ultimate upgrade for your Fox Body or SN95 Mustang.
