StrongArm 4731

StrongArm 4731 Lift Support Overview

StrongArm 4731 is a specific-fit lift support for the hood or hatch application on select Mitsubishi Eclipse and Plymouth Laser models. It uses a pressurized cylinder design to restore controlled opening and holding force for worn lift support hardware.

Built with a black steel outer cylinder, rubber and Teflon materials, and a nylon 10mm ball socket end, this lift support is engineered for smooth operation and consistent support. The StrongArm 4731 is a direct-fit replacement for 1990-1994 Mitsubishi Eclipse and 1990-1994 Plymouth Laser applications.

Detailed Description

The StrongArm 4731 lift support is engineered for direct replacement on 1990-1994 Mitsubishi Eclipse and 1990-1994 Plymouth Laser models. It is a pressurized gas cylinder that helps maintain stable hood or hatch positioning while providing controlled opening and closing action. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

With a 25.24-inch extended length, 14.84-inch compressed length, and 10.4-inch stroke, this StrongArm 4731 unit is built to match the required travel for the listed vehicles. The specific-fit design, steel cylinder, and nylon ball socket connection support consistent installation geometry for Mitsubishi Eclipse and Plymouth Laser lift support replacement.

Common Problems This Part Can Address

• Hood or hatch that drops instead of staying open
• Weak lift support pressure
• Slow or uneven opening motion
• Excessive effort needed to raise the hood or rear glass
• Worn or leaking gas strut hardware

Installation Notes and Tips

Replace lift supports in pairs to maintain balanced support and reliable operation. Confirm the end fittings and length match the original support before installation on your Mitsubishi Eclipse or Plymouth Laser. Verify the mounting points and orientation against the existing hardware so the blade w/bracket and 10mm ball socket ends align correctly.

Quality Assurance

StrongArm lift supports are custom engineered and manufactured beyond industry standards to deliver smoother operation and longer service life. The 4731 is built to meet the demands of the listed 1990-1994 Mitsubishi Eclipse and Plymouth Laser applications.
