Product Details

The QA1 GS501-10650A GM Pro-Coil Front Coilover System is a single-adjustable, bolt-in coilover conversion kit designed for GM applications. Featuring lightweight billet aluminum shocks and USA-made high-travel springs rated at 650 lb./in., this kit delivers a significant upgrade over stock suspension for street performance, autocross, road racing, drag racing, and street rod builds.

The single-adjustable shocks feature an 18-position damping knob that allows easy tuning between a comfortable street ride and a more aggressive performance feel. Adjustments are made at the base of the shock and can be accessed by turning the steering wheel to full lock. The fully threaded shock body enables precise ride height adjustment to dial in stance and weight balance.

QA1's Pro-Coil high-travel springs are engineered with fewer coils and a smaller wire diameter than conventional springs of the same rate and length. This design increases usable travel by widening the gap between coils, reduces unsprung weight, and allows the springs to be compressed to coil-bind without affecting spring rate or free height. Springs feature a silver powder coat finish and are ground at both ends for consistent, accurate operation.

These kits bolt in seamlessly with both OE stamped steel control arms and QA1 tubular control arms, offering flexibility whether you are retaining your stock setup or upgrading for additional performance gains. Every shock is 100% dyno tested and serialized, and units are serviceable and rebuildable by QA1 authorized service centers. QA1 single-adjustable shocks are eligible for a Limited Lifetime Warranty upon registration at QA1.net.

  • 2x QA1 single-adjustable billet aluminum coilover shocks
  • 2x High-travel coil springs — 10 in. length, 650 lb./in. rate, tapered pigtail style

Easy easy! Thanks!

You have an user friendly interface and well displayed, most important information about the product. I also appreciate technical information to make sure that I buy right product. I had a very good experience.

Very easy with great prices and free shipping.

So far very smooth.

easy checkout

I bought 2 pairs of Stainless Steel polished 12x16 mud flaps. I looked at quite a few mud flaps for my Escalade EXT, and these were the only ones I could find that were not plastic or rubber. They are excellent, heavy duty, polished stainless flaps; and mounting hardware was included. They were well packed, shipped fast and at a very reasonable amount. Best of all they were $26.00 cheaper a pair. So I saved $52.00, got fast delivery, and got a very nice product.....Thank you Autoplicity; definitely saved in my favorites....Bill in Pittsburgh, Pa.

Great experience so far, stumbled upon this website searching the internet for Bilstein Shocks...

Cheap price

Awesome! Fast, easy, user friendly, and great prices you can't beat
