J&M Products Street/Race On-Car Adjustable Upper Control Arm (23990-B - Black Powder Coat / Extreme Joint) - 2005-2010 Ford Mustang
Unlock your 2005-2010 S197 Mustang's true handling potential with J&M Products' Extreme Joint on-car adjustable upper control arm. When cornering, your suspension requires the upper control arm to twist to allow for proper axle articulation. Factory stamped arms and rubber bushings lack the necessary compliance, leading to unwanted chassis flex and binding. J&M’s Extreme Joint solution replaces these limitations with a premium spherical bearing, ensuring completely bind-free movement while eliminating the deflection that compromises your car’s handling precision.
Engineered and manufactured in the USA, this arm offers convenient on-car adjustability, allowing you to fine-tune your pinion angle and suspension geometry without the hassle of removal. The "Extreme Joint" features J&M’s high-specification spherical bearing, utilizing a heat-treated 52100 steel ball housed in a 4340 chrome-moly race. Unlike standard PTFE liners, this joint incorporates a superior sintered bronze liner for exceptional durability and smooth, responsive travel. Finished in a durable black powder coat, this arm is built for the rigors of both performance street driving and competitive track use.
