Product Description
The CUMMINS 3933130 OEM INNER THROTTLE RETURN SPRING WITH CLIPS is a genuine Cummins replacement part designed for 1994-1998 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L 12-valve Cummins engine and P7100 injection pump. This OEM spring restores proper throttle pedal return, linkage response, and factory throttle feel.
Over time, factory throttle return springs can weaken, stretch, or break from heat cycles and repeated pedal movement. A worn spring may cause slow throttle return, inconsistent idle behavior, or reduced pedal responsiveness. Replacing the spring with a genuine Cummins component helps restore proper throttle linkage operation and reliability.
Unlike universal replacement springs, the Cummins 3933130 spring includes the correct factory-style molded plastic clips on both ends for secure installation and OEM fitment.

WHY REPLACE THE THROTTLE RETURN SPRING?
The throttle return spring is responsible for returning the throttle linkage to idle position after pedal input. Weak or damaged springs can create inconsistent pedal feel, delayed throttle response, and erratic idle operation. Installing a genuine Cummins replacement spring restores proper pedal action and dependable throttle linkage performance.
