Rough Country Forged Upper Control Arms for 2007-2018 Chevy & GMC Trucks/SUVs — 19401A Forged Aluminium, Oversized POM Joints, 2.5-

Rough Country Forged Upper Control Arms (19401A) are one-piece forged-aluminum replacement arms engineered to provide stronger, longer-lasting steering and suspension performance for lifted 2007–2018 Chevy and GMC trucks and SUVs.

This forged upper control arm kit is built for lift-specific suspensions, combining a solid one-piece forged aluminum construction with oversized POM ball joints and greaseable rubber bushings to resist wear and maintain alignment under heavy loads. Designed for use with 2.5–3.5-inch suspension lifts and compatible Rough Country knuckle and bracket kits, the 19401A replaces stock arms with a bolt-on installation that supports on-vehicle serviceability and long-term durability.

How does the forged one-piece design improve strength and durability?

The single-piece forged aluminum construction eliminates welded joints that can become stress concentrators, giving the arm a higher resistance to bending and fatigue. Forging aligns the metal grain and produces a denser, more reliable structure compared with cast or welded arms.

• Forged solid aluminum body for superior structural integrity.
• No welded seams—reduces fracture risk under heavy loads.
• Built to withstand off-road impacts and repetitive suspension travel.

What makes the POM ball joints and bushings better for lifted applications?

Rough Country uses POM (polyoxymethylene) ball races to reduce metal-to-metal friction, improving durability and lowering maintenance needs versus traditional metal-on-metal joints. The oversized ball diameter increases load capacity and range of motion, especially important when steering geometry changes after lifting a vehicle.

• POM ball race for low friction and extended service life.
• Oversized, fully greaseable ball joint design for improved motion range.
• Clevite OEM-style rubber bushings that accept grease and dampen vibration.

How difficult is installation and what tools or time are required?

Installation is a 100% bolt-on process—no frame modification required—so an experienced home mechanic can complete the job. Rough Country estimates roughly 3–4 hours for the full installation when following the supplied instructions and using common shop tools.

• Bolt-on hardware included for direct replacement with lifted configurations.
• Recommended tools: jack stands, torque wrench, ball joint grease gun, basic hand tools.
• Allow time for alignment after installation to ensure correct steering geometry.

Which vehicles and lift setups are compatible with the 19401A arms?

This kit is optimized for Chevy and GMC full-size trucks and SUVs from 2007–2018 that run 2.5–3.5-inch lift kits or Rough Country knuckle/bracket lift systems. It is not intended for stock-height models, certain "Classic" 2007 body-style trucks, or vehicles fitted with 3.5-inch knuckle, 5-inch, or 6-inch lift kits.

• Compatible with many 2007–2018 Chevy Silverado, Tahoe, Suburban, and 2019 Silverado 1500 LD variations.
• Compatible with many 2007–2018 GMC Sierra and Yukon models, including Denali and XL where specified.
• Intended for 2.5–3.5" Rough Country lift kits and 7" knuckle or 7.5" knuckle configurations.

Who is this for? This Rough Country Forged Upper Control Arm kit is aimed at owners of lifted Chevy and GMC full-size trucks and SUVs who need a stronger, longer-lasting upper arm to preserve steering geometry and handle heavier loads or off-road abuse.
