UMI Performance Stage 2.5 Handling Kits GBF025-R

GBF025-R is built around double adjustable coilovers front and rear, giving separate control over compression and rebound rather than one combined damping setting. Ride height adjusts from stock down to about 2" lower, and the tubular control arms are steel with a red powder-coated finish, running on a Polyurethane/Delrin bushing combination. What's in the kit Beyond the coilovers and control arms, the package includes sway bars at 1.250" up front and 1.000" in the rear, plus all the mounting hardware needed to bolt everything into place. Because compression and rebound adjust independently, you get more range to dial in ride quality than a single-adjustable setup allows. Fitment notes UMI engineers the rear coilover portion around the GM axle housing, so an aftermarket rear axle may take extra fitment work to use with this kit. No welding is called for during installation, and the whole package ships as one kit rather than piecemeal. Common questions What does double adjustable mean here? The coilovers let you tune compression and rebound separately rather than with one combined setting. Is this kit bolt-on? Yes, UMI lists welding as not required.
