Application: 1978-1987 GM G-Body: Regal, Malibu, Monte Carlo

The Spohn Performance rear coil over conversion kit for the for the 1978-1987 GM G-Body: Regal, Malibu, Monte Carlo, etc.

This kit is based on the QA1 Proma Star 18 way single adjustable aluminum coil over shocks:

SINGLE ADJUSTABLE -  Simultaneous compression and rebound adjustment with 18 valving options. Unique to QA1, one knob changes both compression and rebound valving simultaneously, allowing total suspension control in one easy-to-reach location.
DOUBLE ADJUSTABLE - Includes 18 positions of compression adjustment on one knob, and 18 positions of rebound adjustments on the other knob. Each knob is clearly labeled with an "R" for rebound and a "C" for compression, as well as plus and minus symbols for ease of adjustment. These shocks give you 324 Valving Adjustments!
Deflective Disc Valving: Advanced shock technology, increased sensitivity in valving response, control and consistency.
Precision Machined Piston with PTFE Piston Band: Creates accurate piston to cylinder wall seal, improves valving consistency and increases durability.
5/8" Centerless Ground, Hard Chrome Plated, Solid Piston Rod: Precision surface, eliminates piston rod flex increasing valving consistency.
Forged, Machined Aluminum Body: Lightweight, stronger than billet. Bright anodized for unmatched durability and great appearance.
Three Step Sealing System: Advanced aerospace material, exclusive double lip seal design and wiper seal eliminate seal drag and dirt intrusion.
100% Dyno Tested and Serialized: Assures consistency in production and performance.
Spring Mounting Hardware Included: Aluminum spring cap, spring seat, and locking ring included.
Top Shock Mounting: Polyurethane bushings with extreme duty CNC machined t-bars.
Bottom Shock Mounting: Exclusive Teflon/Kevlar race bearings for smooth bind-free operation.
Adjustment: Adjust your ride height as high or as low as you need.

The Spohn Performance rear coil over conversion kit for the 1978-1987 GM G-Body: Regal, Malibu, Monte Carlo, etc. ships to you fully assembled (as pictured) and ready to install. The kit is an easy 100% bolt in installation!

Spring Rates: For a soft stock like ride we recommend a 130# spring. For drag racing and street/strip applications we recommend a 150# spring. For handling performance we recommend a 175# spring. For road racing we recommend a 200# spring. 


New product we are offering!  Rear shock tower brace kit.  Ties the two shock towers together for extra strength. Easy bolt on mod that includes hardware.

Another optional product we are now offering!  These brackets will relocate the bottom of the coilover shock inboard about two inches for more clearance when using rear disc brakes or if you notch the frame rails and have wider wheels that may hit.  These also offer more attachment points for more strength vs the standard lower brackets.  Also includes reinforcement braces for the upper shock mounts.  Easy bolt on mod that includes hardware.
