IMPROVE YOUR GM DRAG CAR LAUNCHES AND LANDINGS WITH AN AFCO ELIMINATOR FRONT COIL- OVER CONVERSION KIT

■ Adding coil-over racing shocks to the front of your GM doorslammer makes perfect sense . Besides removing unnecessary weight and improving steering performance , coil-overs have other advantages :

NEW TH400 , 4L80-E BILLET SERVOS & ADJUSTABLE PIN FROM SONNAX

• Easy ride height adjustment to get the proper stance
• Quick corner weight and pre-load adjustment to fine tune launches
• Pre-load tuning that straightens out the car after a bad launch
• Valving that eliminates bouncing when landing after wheels-up launches
• Increased space around other suspension components
And there ’ s no easier way to do a conversion than with an AFCO Racing Eliminator Front Coil-Over Conversion Kit . The kits give you a bolt-in , no-modification-required way to ditch the OEM components for superior coil-over shocks while simultaneously improving how your car launches and drives down the track .
AFCO ’ s Eliminator Conversion Kits come with your choice of singleor double-adjustable shocks . The difference between them is easy to explain . When a single-adjustable coil-over is tuned , you are adjusting both the rebound and the compression dampening at the same rate . This means that the coil-over will be stiffer or looser in both directions the shock shaft moves . Double-adjustable coil-overs give you more control because you can adjust the compression and rebound rates independently . For instance , you could tune the coil-over to have a loose rebound for great weight transfer and a stiffer compression rate for more controlled landings after wheels-up launches .
AFCO Racing Eliminator Front Coil-Over Conversion Kits are available for 1967-81 Camaro / Firebird , 1964-77 Chevelle / Malibu , 1978-88 Malibu / Monte Carlo , and 1968-79 Nova .
