QA1 Proma Star externally adjustable coilover shocks and struts provide just the right combination of consistency, reaction, and durability for drag racing. They have special valving, which is designed to compensate for high shaft speed, while allowing for low shaft speed control. When combined with the 18 externally adjustable valve settings, they ensure an improved grip on the track from end to end. Other features include a bright-anodized aluminum body, PTFE-lined bearings or polyurethane bushings, a 5/8 in. centerless-ground chrome piston rod, and aerospace-caliber sealing materials.

QA1 offers upper and lower rear trailing arms for Ford and GM applications in boxed, tubular, and heavy-duty adjustable options. All upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end to eliminate bushing bind, allowing the suspension to move smoother for better control. They are powdercoated or zinc plated and anodized for a long-lasting finish. Keep your tires planted firmly on the ground for improved traction and a more predictable, better handling car with a set of QA1 rear trailing arms. Features may include: * Boxed trailing arms are constructed from 0.120 in. wall cold rolled steel tubing for maximum strength and flex elimination. * Tubular trailing arms are constructed from 1 1/4 in. diameter, 0.120 in. wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight. * Boxed and tubular styles feature fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. * Heavy-duty adjustable trailing arms allow easy rear suspension adjustments for optimum handling and traction. Simply loosen the jam nuts and adjust the pinion angle without removing the arms from the vehicle. They replace soft OE differential bushings with polyurethane differential bushings, and they use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end * Adjustable styles are available in aluminum and steel options

QA1 MOD Series coilover shocks 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. Additional benefits and features of QA1 MOD Series shocks: * 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

QA1's rebuildable 5Q twin-tube shocks offer the performance, consistency and tunability racers demand. Formerly known as 51 and 53 Series shocks, the 5Q series is a large body steel shock available in both bearing mount and stock mount configurations. Choose from 7 in. and 9 in. bearing mount bodies or various stock mounted lengths depending on rules and applications. Shocks are also available with rebound adjustable piston rods to adjust valving at the track. Small details add up to provide great overall performance. The black zinc coating ensures a very consistent finish, creating a tight seal every time. The scalloped base loop increases clearances in tight areas like upper control arms and shock mounts. Pistons are made of high-quality raw aluminum, minimizing variations that can be found in anodized parts. You can valve the shock with bleed shims or drill out bleeds to maximize tunability. Order the 5Q Series twin-tube shock model for your application needs. Features: * Applications: Street Stock, Hobby Stock, B-Mod/Sport Mod, Modified * 5Q shocks can be re-valved and rebuilt by racers in a matter of minutes using basic tools * Two-piece bodies make it simple to disassemble and reassemble shocks * The gland features relief cuts and a hyper screw port, making shocks easy to fill and bleed on assembly. * An upgraded seal kit minimizes leaks—especially in high-rebound applications * The compression tube uses a slip fit design to simplify the rebuild process * 5Q shocks utilize a laser-engraved, black-anodized closure nut to make serial numbers and valving easy to read at the track or in the shop * Coilover compatible Note: QA1's steel body shocks can be used in coil-over configurations using the appropriate kits (sold separately). Racers can rebuild and re-valve their own shocks using available tuning and rebuild kits.
