Details & Inspection Notes
The UMI Performance Stage 2 kit, part number ABF803-1-B, is a complete front and rear suspension package built around tubular chromoly control arms, a hollow 1.25" front sway bar, and a solid 1.00" rear sway bar. Gas-charged monotube shocks sit at all four corners alongside matching coil springs, so the kit addresses ride height, body roll, and damping together instead of piece by piece.
What's in the box
Beyond the springs, shocks, and sway bars, the package adds a chassis stiffener, polyurethane bushings in black, and the mounting hardware needed to bolt everything into place. There are no trailing arm mount braces, panhard bar, torque arm, or brake parts in this particular kit, so plan on sourcing those separately if your build needs them.
Common questions
Will this change my ride height? UMI notes that cars running a full-weight big block engine may sit roughly a quarter inch lower in front once the kit goes on.
Does it include brake parts? No. This is a suspension-only package; brake components are not part of the kit.

Suspension Setup & Installation Checklist
- Inspect top mounts, damper seals, bushings, and ball joints prior to fitment.
- Set initial spring preload, collar heights, and damper rebound clicks symmetrically left to right.
- Torque all suspension control arm pivot bolts while the vehicle is at resting ride height (loaded suspension).
- Perform a complete 4-wheel laser alignment once ride height has settled to ensure optimal handling and tire wear.
