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.

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 MOD Series coilover conversion systems put the ability to re-valve your shocks—on your car—into the palm of your hand. These innovative shocks feature QuickTune Technology, an industry-first that provides the ability to adapt to any track, any conditions, any time. The technology consists of interchangeable, dry modular valve pack assemblies, that can be thought of as dozens of finely tuned shocks you can hold in the palm of your hand. They define the valving curve of the shocks, and can be changed without interrupting the oil pathways. Simply unscrew from the shock, bolt-in another one with a new pre-determined valving range—and you're ready to go. There's no mess, no contamination, no air intrusion, and no downtime waiting on someone to re-valve your shocks. Ideal for Circle Track and Street/Strip applications, the shocks are available in a variety of extended and collapsed length models to best fit your vehicle. You get everything you need with these QA1 Rear MOD systems, from shocks to nuts and bolts, complete installation instructions, and even decals! Additional benefits and features of QA1 MOD Series shocks: * All new design delivers force, control, and unmatched tenability * Hard anodized aluminum bodies with PTFE—durable, non-galling surface * Double-adjustable shocks with low-speed bleed adjustments * Large solid piston (with blow-off valve)—improved driver feel and control with up to 1,600 lb. force * High-speed valving adjustment (coarse adjustment)—relates to shock operation during impact events, like hitting a pothole or curb * 24 clicks/settings—wider range of adjustment than comparable shocks * Indexable base eyelet—multiple mounting position to optimize knob access and provide more mounting flexibility * Low-speed valving (fine-tune adjustments)—adjusts ride quality and weight transfer on corner entry/exit; more bleed for softer feel and less bleed for stiffer feel * Piggyback or remote canister options * Unique spring adjuster nut and tool * Thrust bearings included * Superior thermal performance, as oil is in constant contact with outer body * One base shock can be upgraded over time to keep up with increased performance levels of your vehicle
