SPC Performance 86470 Gm Front Control Arms (pr)

The SPC Performance 86470 fixed offset upper control arms are engineered to restore proper front camber and caster alignment on lifted or lowered GM trucks and SUVs. Whether you've added a 3-inch lift or dropped your vehicle 1 inch, these control arms compensate for the caster loss that factory adjusters cannot adequately correct. With a +2° caster change, these arms work in conjunction with OE cam adjusters to dial in precise alignment and restore optimal drivability.

Key Features:

• Fully forged construction delivers maximum strength and durability for demanding applications
• Booted and greasable ball joints designed for long-term reliability and serviceability throughout the life of your vehicle
• xAxis sealed flex joint technology provides free pivot movement for suspension droop and misalignment without binding during OE caster and camber adjustments
• Rubber isolation bushings maintain factory-level noise, vibration, and harshness (NVH) characteristics for a comfortable ride
• Reversible design allows left-to-right swap for -2° caster change on vehicles lowered more than 1 inch
• Complete pair included with arms for both right and left side installation

This kit is ideal for lifted and lowered applications where factory alignment adjusters reach their limits. The cross-axis ball joint design ensures proper suspension articulation while maintaining alignment geometry. For complete alignment solutions, these arms pair with SPC replacement cams (p/n 86375), alignment pins (p/n 86325), and locking plates (p/n 86320).
