Build or service a suspension, steering, or fabrication assembly with this QA1 coilover springs. Manufacturer part number 10HT350 uses the listed 2-1/2in ID High Travel Spring - 10in Length x 350lbs/in - Silver Powder Coated configuration, and compatibility is determined by exact dimensions, threads, mounts, travel, load, and mating components rather than vehicle name alone.
Key Features
- Chrome Silicon Steel: High-tensile alloy wire provides strength consistency and fatigue resistance with cold wound heat treated and shot peened process for long life.
- High Travel Design: Fewer coils and smaller wire diameter create larger gaps for increased suspension travel while keeping the spring lightweight.
- Marked Specifications: Free length and spring rate etched on spring for quick identification during setup and maintenance.
- Silver Powder Coated Finish: Protects against corrosion and wear for reliable performance in demanding racing environments.
- Ground Squared Ends: Ensures flat precise seating in coilover assemblies for straight consistent operation.
- Compresses to coil bind without changing rate or free height.
