SPC Performance 21+ Ford F-150 Front Adjustable Upper Control Arm Kit – Forged Steel Construction

Description

Developed, engineered, tested, and assembled in Colorado, the SPC Performance 35685 adjustable upper control arms are designed to enhance your Ford F-150’s suspension performance. Crafted from forged steel, these control arms provide maximum strength and durability necessary for demanding off-road and heavy-duty applications. The kit is equipped with maintenance-free ball joints featuring a 25% larger stud cross section and E-Nickel coating, ensuring superior strength and corrosion resistance. The modern sealed architecture ball joints and xAxis™ sealed flex joints in bonded rubber sleeves facilitate extended suspension travel, reduced noise, vibration, and harshness (NVH), and improved overall ride quality.

Designed for lifted trucks, the control arms include positive caster built-in to restore proper alignment angles affected by vehicle lift. The adjustment range, combined with OE adjusters, allows precise correction of camber and caster angles, improving handling and reducing uneven tire wear. The control arms enable the tire to be positioned correctly in the wheel well, maximizing clearance for oversized tires without the need for frame or fender modifications. Their forged steel construction ensures maximum strength and clearance, while the full 80° articulation of the ball joint provides excellent suspension flexibility. These features make the SPC Performance control arms ideal for enthusiasts seeking reliable, high-performance suspension upgrades.

The design incorporates a one-piece polymer race ball joint with modern grease formula for smooth, quiet operation and extended service life. The fully sealed architecture prevents contaminants from entering, maintaining optimal grease levels and reducing maintenance needs. This kit is sold as a pair and is suitable for the front of the vehicle, with the necessary adjustments to improve drivability, tire wear, and handling characteristics. Whether you are upgrading for lifted terrain or seeking improved alignment correction, the SPC Performance 35685 control arm kit offers a robust solution for serious truck enthusiasts.
