Bolt-in rear coilover conversion built for consistent drag launches on your F-Body

The UMI Performance 2046-C211-110 rear coilover kit converts the 1982-2002 GM F-Body rear suspension to a true 2-1/2 inch racing coilover setup with a 110 lb/in drag-spec spring rate. UMI2046-C211-110 uses a Viking double adjustable shock with 19-way compression and rebound settings, giving full control over ride height, spring rate, and damping from one bolt-in kit. The FEA-designed lower bracket holds the shock in double shear and only one 3/8 inch hole per side needs to be drilled for installation.

Frequently Asked Questions

What is the 2046-C211-110?

The 2046-C211-110 is a UMI Performance bolt-in rear coilover kit for the 1982-2002 GM F-Body, built with a 110 lb/in drag-spec spring rate and a Viking double adjustable shock.

Why choose the 110 lb/in spring rate over other options?

UMI recommends the 110 lb/in spring for drag racing applications, where a softer initial rate helps transfer weight to the rear tires during launch. Higher rates such as 150, 175, and 200 lb/in are intended for street and road race use.

Does this kit require welding to install?

No. The kit uses a bolt-in design and requires drilling only one 3/8 inch hole per side, with no welding needed.

Can ride height be adjusted after installation?

Yes. The coilover design allows ride height, spring preload, and shock damping to all be adjusted independently once installed.

Is this kit compatible with aftermarket control arm relocation brackets?

Yes. Spacers are included specifically for use with control arm relocation brackets.

How many adjustment settings does the Viking shock offer?

The Viking double adjustable shock offers 19 compression settings and 19 rebound settings, adjusted independently.

Where is this kit manufactured?

UMI Performance designs, tests, and manufactures the 2046-C211-110 kit in Philipsburg, Pennsylvania, USA.

Install Instructions

  1. Support the vehicle safely on jack stands and allow the rear axle to hang freely.
  2. Remove the factory rear shocks and springs from both sides.
  3. Install the double shear lower bracket at the axle mount and drill the single required 3/8 inch hole per side.
  4. Mount the double shear upper bracket at the factory upper shock location.
  5. Install the Viking coilover shock and pre-assembled spring between the upper and lower brackets.
  6. Set the desired ride height and spring preload using the coilover adjustment collar.
  7. Adjust the Viking shock's compression and rebound settings to match the intended use.
