UMI Performance Stage 4 Handling Kits GBF005-2-B

UMI's Stage 4 kit GBF005-2-B centers on 361-position adjustable monotube shocks at both ends, the finest damping adjustment in this handling-kit lineup, paired with a 550 lbs./in. front spring rate. A solid 1.25" front sway bar and solid 1.00" rear sway bar work alongside tubular steel control arms finished in black. What's in the kit The rear end gets adjustable upper trailing arms along with a fixed lower trailing arm and trailing arm mount braces, all running on Delrin bushings. UMI includes the mounting hardware needed for the install, and no welding or chassis cutting is called for to get it bolted in. What to check before buying With 361 damping positions on tap, plan on spending some time dialing in compression and rebound rather than expecting a single ideal setting out of the box. This kit is built around classic muscle cars and performance builds generally, so it's a good fit if you're chasing serious adjustability rather than a simpler fixed-rate setup. Common questions What does 361-position adjustable mean? The front and rear monotube shocks can be set to 361 different damping positions instead of one fixed rate. What's the front spring rate? 550 lbs./in., as listed for this kit. Specifications Feature Details MFG.
