Product Details

The QA1 GS401-11300A Front Pro Coil Single Adjustable Coilover Kit is a bolt-in front coilover system engineered for GM muscle car owners seeking improved stance, ride quality, and performance. Featuring a lightweight billet aluminum shock body paired with an 11-inch, 300 lb/in tapered pigtail coil spring, this kit delivers a significant upgrade over factory suspension with the added benefit of full adjustability.

The single-adjustable shock valving provides 18 simultaneous compression and rebound damping settings, allowing you to dial in everything from a smooth, comfortable cruise to a firm, performance-oriented feel. Ride height is fully adjustable via the threaded shock body and spring seat nut, offering up to 2 inches of drop to achieve the perfect stance. The tapered pigtail spring end ensures proper seating and retention on OE-style lower spring perches.

Key Features:

  • Single adjustable valving with 18 simultaneous rebound and compression settings
  • Lightweight billet aluminum coilover shock body
  • 11-inch free-length coil spring with 300 lb/in spring rate and tapered pigtail end
  • Compressed shock length: 10.13" | Extended shock length: 14"
  • Up to 2 inches of ride height adjustability via threaded body and spring seat nut
  • Bolt-in installation — compatible with OE stamped steel or QA1 tubular control arms
  • High-travel spring design with reduced coil count and smaller wire diameter for faster response and lower unsprung weight
  • 100% dyno tested and serialized at the factory
  • Serviceable and rebuildable by QA1 Authorized Service Centers
  • Made in the USA (Lakeville, Minnesota)
  • Sold as a pair

What's Included:

  • (2) 11-inch, 300 lb/in tapered pigtail coil springs

Everything I was looking for, thanks!

super service

After searching for the best prices for the product that I wanted, I ended up with Autoplicity. I quickly got a response that my product has just been shipped and I am very impressed that Autoplicity is giving me an incentive to write a review on them. This tells me that this company is very concerned with the satisfaction of their customers. I am currently waiting for the order to arrive, but so far, I am extremely confident and happy with Autoplicity!

good so far

This was my first time buying from Autoplicity. I had never heard of the site but gave it a shot. I ordered an Autometer gauge and pod and paid less than the price of just the gauge at other vendors. The two items shipped a day later (I ordered Sunday, shipped Monday). I have no complaints at this time.

So far it has been a good experience

Great experience with Autoplicity. Got online, searched for new shocks, found best value from Autoplicity. Ordered new shocks and received them as promised, installed them and now I am a very satisfied and happy customer.
