Coilover Spring - 2.5in internal diameter, 14in free length, 350 lbs/in rate. Operates in the coilover shock assembly, seating on the shock body between the lower spring collar and the threaded adjustable upper collar.

The spring carries the corner weight of the vehicle while the damper controls wheel motion. Ride height and preload are set by winding the threaded collar, so spring rate and free length together determine both static ride height and the load at which the suspension begins to compress.

This length and rate is specified as the lower spring on the 12in-travel 2.5in coilover (TFR2512 and TFR2512DUAL), and as either the upper or lower spring on the 14in-travel 2.5in coilover (TFR2514 and TFR2514DUAL). At this rate it is typically used as the load-carrying spring in a dual-rate stack.

Match spring rates side to side across an axle to keep the suspension balanced.

Frequently asked questions

What is the TFR-14-78-350 coilover spring used for?
The TFR-14-78-350 is a coilover spring with a 2.5in internal diameter, 14in free length and 350 lbs/in rate. It seats on the shock body between the lower spring collar and the threaded adjustable upper collar, carrying the corner weight while the damper controls wheel motion.
Which coilover does this spring fit?
This coilover spring fits 2.5in shocks by its 2.5in internal diameter and is typically used as the load-carrying lower spring in a dual-rate stack at this 350 lbs/in rate. Springs are selected by shock specification, travel and corner weight rather than by vehicle, so match it to your coilover platform.
How do I set ride height with this spring?
Ride height is set by winding the threaded collar on the coilover, not by the spring alone. The spring rate and 14in free length together determine static ride height and the load at which the suspension starts to compress. Match spring rates side to side across an axle to keep the suspension balanced.
