QA1 Proma Star Double Adjustable Coilover Systems

Dial in your ideal ride quality with the independently adjustable compression and rebound valving of QA1 Proma Star double adjustable coilover systems. They offer the perfect balance of street-ability and performance and are an ideal choice if you plan to use your car on the road and occasionally take it to the track. With QA1 Proma Star double adjustable coilover systems you will improve overall handling, increase suspension tunability, and gain the ability to adjust ride height quickly and easily for a perfect stance and corner balance your car, maximizing performance. They are easy to install with basic hand tools in the factory mounting locations and does not require the use of a toe link relocation kit. Coilovers are available with multiple spring rate options to help you find the perfect option for your intended use. The medium springs are great for cars that will mostly be used on the road. The firm option is geared toward track-oriented cars, further reducing body roll under hard cornering, and providing a more planted feel.

QA1 MOD Series Pro Coilover Systems

Don't be limited to adjustments! Completely re-valve in minutes with the QA1 MOD Series Pro coilover systems. Designed specifically to meet the demands required by today's high performance drag race and handling/pro-touring cars, QA1's multi-patent-pending MOD Series shocks will transform the way racers respond to changing track conditions and configurations. The key element to this tunability is QuickTune Technology: dry modular valve packs that can easily be swapped out, all while the shocks remain on the car. An industry first, MOD Series shocks can easily be re-valved without interrupting the oil path or opening up the shock for debris and air contamination. Medium compression and rebound valve packs come standard; soft or firm compression and rebound valve packs are also available. Once the desired valving is in place, the unique double-adjustable design (with adjustable low-speed bleed) allows for fully independent control over the compression and rebound characteristics. With all these adjustability options, MOD Series shocks achieve an expansive force curve capability and an unprecedented level of tunability. The shocks also feature mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas, and the base eyelet is indexable, so you can unbolt and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, MOD Series coilovers are 100 percent dyno-tested and serialized. Order the kit recommended for your vehicle.

QA1 1963-87 C10 Front Coilover Conversion Systems

QA1 1963-87 C10 front coilover conversion systems are a great upgrade to your C10 front suspension. Each kit comes with QA1's proven single or double adjustable coilover shocks—so you can change the valving to meet your specific needs—along with a variety of spring rate options. These shocks allow for ride height adjustability and are 100 percent dyno-tested and serialized. The QA1 C10 upper and lower control arms are manufactured from 12-gauge HSLA steel tubing for increased strength and are powdercoated for long-lasting durability; they're topped off with performance ball joints and low-friction, maintenance-free bushings. These kits will add up to 7 degrees of caster for more stability, and allow for optimum camber adjustment in a lowered truck. For those on a budget, QA1 also offers kits without the upper control arm—which will add 3-4 degrees of caster, while still providing ride height adjustability with coilover shocks. Order the model designed for your vehicle application.
