Extend Spring Cup w/ Jack Screw 8in

The Extend Spring Cup w/ Jack Screw 8in from WEHRS MACHINE is a precision suspension component designed for vehicle builders and mechanics who require fine-tuned ride height control and spring preload adjustment. This component is particularly useful for those working on performance vehicles, including street performance builds, drag racing platforms, and circle track setups.

This extended spring cup serves as the interface between the coil-over suspension system and the chassis, allowing for repeatable, micro-adjustable suspension geometry tuning without disassembly. The integrated jack screw mechanism enables precise height adjustment without removing the spring assembly, ensuring that the component remains thread-locked under load even in high-vibration environments.

Ideal for vintage and modern hot rods, dirt track racers, and street performance enthusiasts, this spring cup is engineered to handle repeated adjustment cycles. Its robust construction is critical when testing different spring rates or load scenarios across various vehicle configurations, making it a valuable addition to any performance suspension setup.
