A-Arm Slug 7/16

The JOES Racing Products A-Arm Slug 7/16 is a precision control arm caster slug engineered for high-performance suspension tuning on slotted upper control arm assemblies. This aluminum component features a 1/2-inch ID hole with a 7/16-inch offset and black anodized finish, providing the adjustability needed for critical caster and camber alignment on road racing, autocross, and performance vehicles.

The 7/16-inch offset specification enables fine-tuned geometry adjustments on JOES slotted upper control arms, allowing technicians to dial in precise caster angles for optimized tire contact and steering response. The black anodized aluminum construction provides corrosion resistance while maintaining a minimal weight footprint—critical considerations in competitive motorsports where suspension geometry directly affects lap times and handling consistency. At just 0.03 lbs, this slug integrates seamlessly into suspension packages without adding unsprung mass.

This component is designed for road race teams, autocross competitors, and performance vehicle builders who require OEM-quality replacement parts or upgrade options for JOES Racing slotted upper control arm platforms. Sold individually, the slug accommodates one suspension corner—typical installations may require multiple slugs depending on the suspension configuration and desired geometry changes.

JOES Racing Products manufactures suspension components to tight tolerances for the road racing and performance tuning market. Verify fitment with your specific control arm model and suspension geometry calculator before installation to ensure proper alignment and safe operation.
