QA1 Kit Pro Coil Aluminium Single Adjustable 10-450

SKU CH-XTHW-7AZTR

Aluminium single-adjustable coil-over kit covers 10-450 lb spring rates for 1970-81 GM F-Body

  • Product typeInstallation Tools
  • Pro coil kit covers 10 to 450 lb-in spring rates
  • Single adjustable damping lets you tune rebound control
  • Aluminium body reduces unsprung weight for sharper handling
  • Designed for 1970-81 GM F-Body applications

QA1 Pro Coil Kit for GM F-Body

This aluminium single-adjustable coil-over kit is built for 1970-81 GM F-Body chassis. It targets track-day drivers and street enthusiasts who want height and damping control without a full custom fabrication project. The tapered flat spring design fits the factory mounting points and supports large-diameter tyres for maximum grip.

Straightforward bolt-in with basic tools

Installation uses the original shock mounts and requires only standard hand tools and a spring compressor. The single-adjustable valve lets you tune rebound on the car, but compression stays fixed. Builders who need independent compression and rebound adjustment or a double-adjustable setup will need a different kit.
