Lower Nova LH Large Screw In

The U-B Machine Lower Nova Left-Hand Large Screw-In is a precision-engineered lower control arm designed for GM F-Body and G-Body platform vehicles. Built from high-strength steel and finished with a durable black powder coat, this component features a screw-in ball joint design that delivers repeatable geometry and reliable performance in both street and competition applications. The left-hand configuration and large diameter screw-in ball joint make this the preferred choice for builders seeking maximum adjustability and strength in their suspension geometry.

Weighing 12.7 pounds and measuring 16.75 x 5.25 x 24.25 inches, this lower control arm accommodates the specific mounting points and clearance requirements of F-Body (Camaro, Firebird) and G-Body (Monte Carlo, Cutlass, Regal) platforms. The screw-in ball joint design allows for precise caster and camber tuning without requiring press-fit installation, reducing labor time and enabling field adjustments. The powder coat finish provides corrosion resistance during storage and use, protecting the steel substrate while maintaining a professional appearance. This configuration works seamlessly with OEM and aftermarket suspension components commonly used in vintage muscle car restoration and performance builds.

This lower control arm is ideal for restoration shops, weekend fabricators, and serious enthusiasts rebuilding or upgrading suspension on classic Chevrolet muscle cars. Whether you're restoring a second-generation Camaro, updating the geometry on a street Cutlass, or building a competition-grade F-Body, the Nova LH Large Screw-In delivers the structural integrity and adjustability expected in modern suspension design. The screw-in ball joint approach is particularly valued in applications where suspension geometry needs to be fine-tuned after initial installation, allowing builders to dial in weight transfer characteristics and handling without complete teardown.

U-B Machine components are recognized within the classic car and street rod community for precision manufacturing and attention to suspension geometry. The Lower Nova series represents the company's focus on fit-and-function alternatives to worn OEM arms, offering modern manufacturing tolerances combined with traditional design principles that suit vintage platforms.
