Tremendous front grip and a range of features can be yours with UMI’s 305756-3 kit. This a-arm kit allows for 10 degrees of caster while maintaining the standard track width and wheelbase. The removable lower shock mount enables spring and shock changes at the track. The tall lower ball joint optimizes roll center, camber gain, center of gravity, and lowers ride height by ½”. Delrin bushings ensure the lower a-arm travels smoothly for bind-free operation. The new lower a-arm works in tandem with our popular 3056-3 adjustable upper arm, which offers minimal shim adjustability, 1” taller-than-stock ball joints, and exceptionally smooth rod ends.
Also included on the lower a-arm is a double shear sway bar mounting system, compatible with UMI sway bars and many aftermarket units designed for stock locations. An adjustable aluminum steering stop limits steering lock to prevent tire and wheel damage. It is available in UMI red or black powder coat, 100% designed, manufactured, and tested with pride in the USA, and battle-tested on the iconic UMI Green Machine.
Performance note: UMI recommends adding the P/N 3060 bump steer kit for optimal performance.
Installation Notes: The 3057-1 is a versatile competition a-arm that can be used with various springs and shocks, including hybrid coilover kits and Ridetech setups. Please contact us for further assistance. Overall, UMI’s 305756-3 kit provides superior performance and durability for your vehicle.
