The UMI Watts Link is designed as a key component to optimize the 3rd and 4th Gen F-car solid axle rear suspension. The combination of lateral locating ability and roll center height adjustment makes a Watts Link the best choice for axle location in handling cars. UMI’s premium P/N 2080 features a unique construction which is laser cut for accuracy and boxed for awesome strength vs weight. The propeller is designed with bulletproof Delrin bushings and a castle nut/cotter pin arrangement to ensure reliability and long service life. The locking design eliminates the need for over-tightening which ensures safety combined with smooth propeller movement. UMI-built aluminum sleeves allow for on-car lateral location adjustment while the bracket system holds the other end securely. The slotted design makes for easy parallelism adjustment and ensures smooth travel throughout the 2.5” adjustment range. Exhaust clearance is a major design consideration in the UMI 2080 and it has increased clearance over competitors designs. This will clear most large single over-the-axle systems as well as many dual pipe systems. The UMI P/N 2080 is built entirely in-house and always of USA materials. Raced with pride on the UMI Performance ’99 Camaro.


Note: This kit requires aftermarket sway bar clamps on the rear, such as the UMI # 2244. These clamps space the rear sway bar down, in order for the watts link axle clamps to have proper clearance. A minimum of 1.125” of spacing is required between the axle tubes and rear sway bar.
