QA1 2-1/2in ID High Travel Spring - 9in Length x 650lbs/in - Black Powder Coated

This QA1 high travel spring delivers precise 650 lb/in rate in a compact 9in free length with 2.5in ID and 3.875in OD. Designed for universal fit in most coilover shocks and struts on drag cars, street rods, muscle cars, and circle track racers. Its high-tensile chrome silicon construction cuts weight while providing more suspension travel and quicker response for sharper handling.

Key Features

  • High Travel Design: Fewer coils and smaller 0.120in wire diameter create larger gaps for greater suspension travel without sacrificing strength
  • Weight Reduction: Lighter than standard springs to lower unsprung mass and improve acceleration, braking, and cornering
  • Fast Reaction: Reduced mass allows springs to cycle quicker for better shock control and chassis stability
  • Black Powder Coat Finish: Resists corrosion and chips for long-lasting appearance in harsh racing environments
  • Made in USA: Crafted from high-tensile chrome silicon alloy steel with 5.8 active coils for reliable performance

Product Notes

  • Verify shock or strut spring pocket measures 2.5in ID minimum before install
  • Avoid extreme heat cycles over 400F to maintain rate consistency
  • Handle with care to prevent bending during storage or transport

Installation Notes

  • Professional installation recommended.
  • Compress spring with tool rated for 650 lb/in rate during assembly
  • Compatible with QA1 Pro Coilover systems and other 2.5in ID spring perches. check seat width 2.5in in/out
