Rough Country Forged Upper Control Arms for 07-18 Chevy/GMC Truck & SUV — 19401A

These arms are built from forged solid aluminum for maximum strength with no welding weak spots. POM ball joints provide a greater range of motion and easier installation, while Clevite OEM-style rubber bushings offer full greaseability. Best for lifted Chevy/GMC trucks and SUVs requiring reliable joint angles and robust performance. Limitation: aluminum components may require careful torqueing during installation to avoid over-stressing the joints.
Best for: Lifted Chevy/GMC 07-18 models that need strong, precision arms with greaseable bushings. Best if you want reduced weld-related weak points and easier alignment after install.
Rough Country Forged Upper Control Arms for 2007-2018 Chevy/GMC 1500-19401ARED

This version mirrors the 19401A build with forged aluminum, offering strength and durability for lifted light-duty trucks. It includes POM ball joints for better motion and fully greaseable bushings to simplify service intervals. Best for owners who want a direct upgrade path for lifted pickups without changing other suspension components. Caution: ensure compatibility with your specific 6-lug configuration and verify fitment for any special trim packages.
Best for: 2007-2018 Silverado/Sierra and related models needing a durable, greaseable arm with excellent range of motion. Choose this if you want a plug-and-play upgrade that matches OEM-style bushings.
KSP Upper Control Arm 2-4″ Lift — 2-4″ Lift for 07-16 Silverado/Sierra 6-Lug

Constructed from 1.25” DOM tubing, these arms aim to deliver superior strength and durability for lifted trucks. The kit emphasizes a safer, reinforced structure and proper ball-joint angle correction for 2–4″ lifts. A noted caution is to verify proper grease lubrication intervals, as over-greasing can damage the zerks, and alignment is required post-installation. Best for: 6-lug Chevy/Sierra models needing robust, weld-free upgrades with good misalignment correction.
Best for: Lifted 6-lug Chevy/Sierra trucks that prioritize safety and stiffness in the upper control arm design. Choose this if you want a rugged upgrade with strong tubing and reinforced joints.
KSP Upper Control Arm Fit for Sierra Silverado1500 — Stage 2.0

These arms are designed for a broad 6-lug lineup and use 1.25″ DOM tubing for enhanced rigidity. Notable features include a protectively coated ball joint and a greaseable socket to reduce wear. Best for 2007-2018 Silverado/Sierra families that require precise alignment after lift and a durable, long-life upper arm. Limitation: Some users report needing careful alignment after installation due to altered suspension geometry.
Best for: Everyday daily drivers and off-roaders who want a durable, rust-resistant upper control arm and straightforward maintenance. Avoid if you need a non-greaseable sealed joint.

Buying Guide
Key considerations when choosing upper control arms for a 6-inch lift:
- Material and strength: Forged aluminum versus tubular steel affects weight, stiffness, and corrosion resistance.
- Joint type and serviceability: POM versus ball joints; greaseable versus sealed joints.
- Fitment accuracy: Ensure the arm is designed for your specific 6-lug configuration and year model.
- Wheel clearance and geometry: Lifts require arms that correct ball joint angle and maintain camber and toe alignment.
- Installation complexity: Some arms are bolt-in; others demand alignment adjustments or professional mounting.
- Maintenance and durability: Grease ports, bushing design, and fabrication method influence longevity under off-road loads.
FAQ
- Q: Do upper control arms affect alignment after a 6-inch lift?
A: Yes. They correct ball joint angle and help maintain camber and caster, reducing wear and improving steering stability. - Q: Are forged aluminum arms better than stamped steel for lifts?
A: Generally yes for strength-to-weight and corrosion resistance, but check compatibility with your lift kit and budget. - Q: Should I grease greaseable ball joints after install?
A: Yes, follow the manufacturer’s guidance for lubrication intervals to reduce wear and extend life. - Q: Can I reuse stock fasteners with aftermarket arms?
A: Often not recommended; use supplied hardware and follow torque specs to ensure proper seating. - Q: Is alignment required after installing new upper control arms?
A: Yes. Alignment is typically required to ensure proper geometry and tire wear. - Q: Are these arms compatible with multiple brands?
