Screw Jack 1in-8 UNC 1 12in Long Swivel Cup

The Screw Jack 1in-8 UNC 1 12in Long Swivel Cup by WEHRS MACHINE is a precision-engineered support component designed for serious automotive fabrication, chassis work, and suspension modifications. This hardened steel jack is essential equipment for builders and mechanics who need reliable, repeatable support when adjusting ride height, aligning components, or performing fine adjustments during vehicle setup.

The 1-inch diameter threaded shaft and UNC 8 threads-per-inch specification make it compatible with standard chassis jacking points and fabrication rigs used across performance shops and race teams. Built with a rotating swivel cup head, this jack accommodates varying surface angles without binding or slipping, protecting both the jack and your vehicle's components from damage. The 1.5-inch long threaded section provides adequate engagement depth for safe load distribution, while the extended 15.35-inch overall length allows access to hard-to-reach adjustment points on modern chassis and frame designs.

At 2.04 lbs, the WEHRS MACHINE unit delivers robust load capacity with minimal weight penalty—critical when building lightweight race vehicles or working within tight engine bay constraints. The precision machining ensures consistent thread engagement and eliminates wobble that can compromise suspension geometry measurements. This screw jack is ideal for fabricators, suspension specialists, and performance mechanics performing coilover installation, frame rail adjustment.
