Coilover Spring - 2.5in internal diameter, 12in free length, 300 lbs/in rate.

Cylindrical coilover spring for a 2.5in coilover damper, seated between the threaded adjustable lower spring seat and the upper retainer. The threaded seat sets ride height and preload; the spring rate governs how the corner carries sprung weight and how firmly it resists compression - a higher rate suits greater load or tighter body control, a lower rate gives more compliance and wheel travel.

Springs of this type are selected by damper specification, available travel and corner weight rather than by vehicle, and can be run in a dual-rate stack where the coilover platform accepts a divider.
Fitment Notes Universal coilover spring — 2.5in ID, 12in free length, 300 lbs/in rate. Fits any 2.5in coilover platform; not model-specific.

This is a cylindrical coilover spring with a 2.5in internal diameter, 12in free length and a 300 lbs/in rate. It seats on a 2.5in coilover damper between the threaded adjustable lower spring seat and the upper retainer, where the threaded seat sets ride height and preload.
What vehicle does this spring fit?
This spring isn't model-specific. It fits any 2.5in coilover platform and is selected by damper specification, available travel and corner weight rather than by vehicle. Match the 2.5in ID and 300 lbs/in rate to your coilover build and corner load.
What does the 300 lbs/in rate affect?
The 300 lbs/in rate governs how firmly the corner resists compression. A higher rate suits greater load or tighter body control; a lower rate gives more compliance and wheel travel. It can be run in a dual-rate stack where the coilover platform accepts a divider.
