The new Pro Comp Pro Runner Control Arms deliver amazing performance and increased durability for lifted, leveled or stock trucks.

The factory upper control arms’ weak ball joints and stamped steel construction are not designed to handle off-road use or the riggors of hard use off-pavement.

Pro Comp has engineered the new Pro Runner ™ Control Arms utilizing oversized stainless steel FK uniball joints. The big uniball joints provide unparalleled strength over factory ball joints.

Heavy duty 1.25″ chromoly tubular construction and reinforced pivot bushing mounts are used to eliminate flex and handle the added load from extreme suspension cycling. Large PTMEG pivot bushings are equipped with Zerk fittings for easy maintenance and quiet operation.

Each arm is finished in a durable black powder coat finish for years of lasting performance.

Backed by the Pro Comp Promise Lifetime Warranty, the only 100% transferable lifetime warranty, Pro Comp promises that its products will last a lifetime or we will replace it free of charge.
