and rod end components. Their Pro Coil shock lineup is engineered for classic muscle car applications where factory shock geometry does not accommodate aftermarket coil-over conversions. Every GS501 shock leaves their Lakeville, MN facility 100% dyno tested and serialized, and can be returned to any QA1 Authorized Service Center for rebuilding or revalving to maintain long-term performance.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\n\u003cstrong\u003eWhat is the QAPGS501 and what does it fit?\u003c\/strong\u003e\n\u003cp\u003eThe QAPGS501 is the QA1 GS501 Pro Front Coil-Over Shock sold as a single unit without springs. It is designed for 1964-1988 GM A-Body, F-Body, G-Body, and X-Body platforms including Camaro, Firebird, Chevelle, El Camino, Nova, Monte Carlo, Malibu, Regal, Cutlass, and 1982-2004 S-10 \/ S-15 trucks running QA1 Pro Coil front suspension setups.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the QAPGS501 come with springs?\u003c\/strong\u003e\n\u003cp\u003eNo. The QAPGS501 GS501 is the shock only. QA1 Pro Coil springs must be ordered separately. QA1 recommends spring rates based on vehicle front-end weight: 400 lb\/in for small-block builds, 500 lb\/in for big-block builds in most A-Body and F-Body applications. Refer to QA1's spring rate chart for your specific platform.\u003c\/p\u003e\n\n\u003cstrong\u003eHow does the single adjustable valving work on the GS501?\u003c\/strong\u003e\n\u003cp\u003eThe GS501 shock features 18 valving positions adjustable via the knob at the top of the shock body. Turning the adjuster changes compression and rebound damping simultaneously. Lower settings provide a softer, more compliant ride; higher settings firm up the shock for performance driving or autocross use.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat tools are required to install the QAPGS501?\u003c\/strong\u003e\n\u003cp\u003eStandard hand tools are needed for the bolt-in installation. To set ride height using the threaded body adjustment, a spanner wrench is required (QA1 P\/N T114W or T115W, sold separately). Optional thrust bearing kits (QA1 P\/N 7888-109) can be added for smoother suspension articulation on lowered applications.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I use the QAPGS501 on a 1967-1969 Camaro or Firebird?\u003c\/strong\u003e\n\u003cp\u003eYes. The GS501 shock is compatible with 1967-1969 Camaro and Firebird front suspension geometry at stock mounting positions. QA1 recommends 400 lb\/in springs for small-block builds and 500 lb\/in for big-block builds on these F-Body platforms. Refer to QA1 installation instructions for bump stop positioning specific to first-generation F-Body applications.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the QAPGS501 rebuildable?\u003c\/strong\u003e\n\u003cp\u003eYes. Every QAPGS501 GS501 shock is individually serialized and designed to be serviced and rebuilt by QA1 Authorized Service Centers. This keeps long-term ownership costs lower than replacement-only shocks and makes revalving possible as your build or driving style changes over time.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat ride height adjustment does the GS501 provide?\u003c\/strong\u003e\n\u003cp\u003eThe fully threaded body on the QAPGS501 provides 0 to 2 inches of front ride height lowering adjustment. This allows fine tuning of front-end stance and weight distribution without changing springs or other suspension components.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat warranty does the QA1 GS501 carry?\u003c\/strong\u003e\n\u003cp\u003eThe QAPGS501 is covered by QA1's Limited Lifetime Warranty for as long as you own the vehicle. Warranty registration is completed at QA1.net\/Warranty. The lifetime warranty applies to QA1 single-adjustable shock absorbers used in normal performance driving applications.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I run the QAPGS501 on a lowered or modified suspension?\u003c\/strong\u003e\n\u003cp\u003eThe QAPGS501 is designed to accommodate 0 to 2 inches of front height reduction at stock mount locations. Running significantly lower than factory ride height may affect shock travel at full droop or full bump. Verify that the 10.125 inch compressed and 15 inch extended lengths work within your specific suspension geometry before installation on heavily modified cars.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eSafely lift and support the vehicle with jack stands under the frame, with front suspension hanging freely\u003c\/li\u003e\n\u003cli\u003eRemove the factory front shocks from the stock upper and lower mount positions\u003c\/li\u003e\n\u003cli\u003eThread the spring perch collar onto the QAPGS501 shock body to your desired ride height position\u003c\/li\u003e\n\u003cli\u003eInstall QA1 Pro Coil spring onto the shock body, seating it between the lower perch and upper spring seat\u003c\/li\u003e\n\u003cli\u003eInstall the QAPGS501 assembly at the stock upper stud and lower bar pin mount positions, securing all hardware to vehicle torque specifications\u003c\/li\u003e\n\u003cli\u003eSet the ride height adjustment using spanner wrench P\/N T114W or T115W to achieve desired stance\u003c\/li\u003e\n\u003cli\u003eSet valving adjustment to your starting point (typically 9 of 18 for street use) and adjust as needed through testing\u003c\/li\u003e\n\u003cli\u003eCheck alignment after installation and adjust caster, camber, and toe to QA1 specifications for your platform\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
