Product Details

The QA1 GS501-10350A Pro Coil Single Adjustable Coil-Over Conversion System delivers precise suspension tuning for classic GM muscle cars and A-body platforms. This complete front coil-over kit features QA1's aluminum body single adjustable shock with integrated coil spring assembly, engineered for vehicles with front end weights between 1,701-1,800 lbs.

Key Specifications:

  • Shock dimensions: 10.5" compressed length / 15" extended length
  • Spring rate: 350 lbs/in with 10" free length
  • Single adjustable rebound damping for tunable performance
  • Aluminum shock body construction for reduced weight
  • Tapered pigtail spring design (Style 'A')
  • Stud-type upper mount and T-bar lower mount configuration

Installation Notes:

  • Compatible with 1955-1957 Chevy Car, 1964-1967 Chevelle/Malibu/El Camino, Skylark/GS, Cutlass/442/F85, and GTO/LeMans models
  • Some applications may require lower A-arm removal for installation due to shock body diameter
  • Control arm shock openings may need enlargement to accept QA1 shock body
  • Stud mounts measured to shoulder; add 13/16" per stud for installed compressed length

This Pro Coil system transforms vintage GM front suspension with modern adjustable damping technology, allowing drivers to fine-tune handling characteristics for street or performance applications.

QA1 Coilover Spring and Shock Assembly GS501-10350A

Great customer service and support. a live person answered the phone and was able to reccomend the correct product for my vehicle. Best price online too........i woould most absolutely use them again! Great company!

Right item, right price !

I saved over a hundred$ on a set of electric cooling fans. so the prices r great but it took 4 days to process and ship my order so well see how long it takes to get here but overall I would rather save money than get fast shipping

Lowest prices of what I was looking for and super fast shipping!!

Great prices, great service, fast shipping!

SO far, so good. We ordered a new Weathertech Trunk Liner from Autoplicity for our new VW SportWagen. We were pleased to find exactly what we were looking for for $50 less than other locations.
