QA1

Tubular braces work with GM A-Body and G-Body trailing arms to reinforce the rear trailing arm mounts for major improvements in traction with less wheel-hop and more power to the ground. Includes all necessary hardware for installation and are sold in pairs.

QA1 offers spanner wrenches and thrust bearing kits individually and as a complete kit. Ratchet Spanner Wrench #T115W The ratchet spanner wrench is great for tight working conditions and can be used on all QA1 drag and street shocks except Streeters/Economy Streeters. Kit includes two wrenches for use with a 3/8” drive ratchet that fit either the spring seat adjuster nut or lock nut.

When swapping a GM engine into a Mustang, these GM transmission crossmembers are required to bolt in the transmission. Polyurethane transmission mount and all necessary mounting hardware included. Made in the USA.

QA1 Front Sway Bars are manufactured from lightweight hollow-core (4130) Chromoly steel for maximum strength and durability. The CNC forming ensured precision fitment for a true bolt-on installation. A gloss black powder coated finish is applied for lasting durability and corrosion resistance. They also include greasable graphite polyurethane bushings and high quality plated hardware.

QA1 offers bolt-in Rear Coil-Over Conversion Kits for 1978-1996 GM B-Bodies. These kits include specially designed USA made mounting brackets and single or double adjustable aluminum shocks, springs and all necessary hardware.  Springs are 300 in/lb.

This system will fit B-Body wagons of the same vintage, but the rear crossmember will need a small amount of clearancing.

Don’t be limited to adjustments! Completely re-valve in minutes with the MOD Series shock. 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 shock 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 shock remains on the car. An industry first, the MOD Series shock can quickly and easily be revalved without interrupting the oil path or opening the shock up for debris and air contamination. Medium compression and rebound valve packs come standard; soft or firm compression and rebound valve packs 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, the MOD Series shock achieves an expansive force curve capability and an unprecedented level of tunability. The shock also features 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 it and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, the MOD Series shock is 100% dyno tested and serialized and proudly made in QA1’s Lakeville, Minnesota facility.

These QA1 GM Pro Coil Systems are available for 1971-1996 Impalas and Full Size GM vehicles, including Full Size Chevy, Buick, Oldsmobile and Pontiac models, and even Ford full size vehicles and Galaxies. They are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling.

QA1’s Pro-Touring Control Arms are the answer to your handling needs for autocross and road course. Designed with QA1?s Ultra Low Friction Ball Joint, these arms will eliminate flex and provide bind-free movement. The one inch longer upper ball joint stud improves camber gain to keep the tire contact patch optimal for superior cornering grip. QA1?s ball joints are adjustable and rebuildable for tuning with different stud lengths. Configured for QA1 Pro Coil Systems with double shear lower mounting. The combination of high strength tubing and billet aluminum cross shafts make these arms amount to the lightest on the market with improved strength and durability. Robotically welded and high-quality powder coated these street control arms look great. All of these arms are designed to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber when used together. When used independently they will add approximately half of the preceding numbers.

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. This keeps the tires planted firmly on the ground for improved traction and a more predictable, better handling car. For a long-lasting finish, tubular and boxed trailing arms are powder-coated gloss black, while the adjustable arms are zinc plated and anodized. Boxed Trailing Arms are constructed from 0.120” wall cold rolled steel tubing for maximum strength and flex elimination. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Tubular Trailing Arms are constructed from 1-1/4” diameter, 0.120” wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight. These trailing arms have 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 to allow the rear suspension to move more freely and eliminate bushing bind. All parts sold in pairs.

QA1?s Street Control Arms are the perfect upgrade for any vehicle used primarily for cruising and long distances. Configured for QA1 Pro Coil Systems with double shear lower mounting. The combination of high strength tubing and billet aluminum cross shafts make these arms amount to the lightest on the market with improved strength and durability. Robotically welded and high-quality powder coated these street control arms look great. These control arms use polyurethane bushings which will isolate road noise for smoother ride, yet stiff enough for great handling. The high-quality integrated ball joint included with this control arm setup is stronger than the factory ball joint and provides a long-term service. All of these arms are designed to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber when used together. When used independently they will add approximately half of the preceding numbers.
