This is a good shock for a car that needs to start turning. This shock is the starting point of turning a Mod Lite, a RF1-40 has a small amount of turn in it and still allows drive.

Shock works well on an 200 pound spring but that maybe it max spring rate that it can turn.

5.5 rebound/ 1 compression @ 100 psi

Shock is marked as:
