JOES Racing Products 15580-SLB 12" Slotted Bearing Style Upper Control Arm with Screw-In Ball Joint

The JOES Racing Products 15580-SLB is a tubular upper control arm featuring slotted bearing style construction, measuring 12 inches in length with a 10-degree screw-in ball joint configuration. Manufactured from high-quality 0.095-inch steel tubing with a durable black powder coat finish, this A-arm is engineered for circle track and road racing applications.

Key Features:

• Four sealed roller bearings eliminate nearly all resistance, providing incredibly smooth rotating action
• Machined housings retain two bearings on each side, eliminating weld distortions that can create binding
• Dual-hole 1/2-inch aluminum or steel shaft precision-machined to close tolerances, minimizing flex and binds
• Spacers hold bearings rigidly in place while tight shaft tolerances eliminate unwanted suspension movements
• Modular design can be unbolted for installation on frames requiring A-arm mount on the backside

TIG-welded construction ensures maximum strength and durability for demanding racing conditions. The slotted bearing design provides superior adjustability and performance compared to traditional bushing-style control arms.
