Progress Technology Coil Over Application Guide
Progress Competition Series Take-apart Struts feature threaded steel bodies, oversize rod guides and hefty 14mm or 22mm rods for durability.
Shorter Struts
30mm shorter strut bodies for lower ride heights, improved ride quality and traction.
A) Polyurethane Components
Polyurethane Short Stops allow additional wheel travel. New strut top bushings and spring isolators also included.
B) Take-Apart Design
Strut tops are threaded for easy revalving. Custom valving is simple to install for road racing and drag racing. "How-to" video available.
C) Big Bore Size
Large 35mm piston and twin-tube cellular gas construction for consistent damping.

Progress engineers have taken the race-proven components from our winning Competition Series Take-Apart Coil-Over System and integrated them in a new series. This Competition Series II Coil-Over System uses shorter-than-stock sealed struts and slide-over height-adjustable threaded sleeves.
