The lighter design increases travel through greater spacing between the coils, reduces unsprung weight, and reacts faster to optimize suspension performance. Careful heat treating and post-processing improve fatigue life, and the coil design lets the spring compress to coil bind without affecting spring rate or free height. This spring has a 2-1\/2 inch inside diameter, a 12 inch free length, and a 150 lb\/in rate, finished in black powder coat and ground square at both ends for straight, consistent operation.
