Detailed Description

StrongArm 4642 is a back glass lift support built for rear hatch glass service on compatible Chevrolet Blazer and GMC Jimmy vehicles. It uses a pressurized cylinder design to hold the rear window glass in the open position and provide controlled movement during opening and closing. The steel outer cylinder, nylon ball socket ends, and 49.0 maximum force rating support consistent operation in rear glass applications where stable lift assistance matters. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With: Fits 1995-2005 Chevrolet Blazer, N/A. Fits 1995-2001 GMC Jimmy, N/A with Dropgate. StrongArm 4642 is a direct-fit replacement for these rear glass applications and is identified by part number 4642 in catalog and service lookup use.

Common Replacement Reasons

• Rear glass drops instead of staying open
• Liftgate glass feels heavy or difficult to raise
• Back window opens unevenly or closes too quickly
• Worn gas pressure causes weak support at the rear glass
• Original lift support no longer holds the hatch glass securely

Installation Notes and Tips

Verify the vehicle year, make, model, and rear glass configuration before ordering. This support is a specific-fit part, so matching the end fittings and compressed/extended lengths is important for proper operation. For service consistency, replace lift supports in pairs when the opposite side is also worn, and confirm the rear glass opens and closes smoothly after installation.

StrongArm lift supports are custom engineered and manufactured beyond industry standards to deliver smooth operation and long service life in automotive use. Part number 4642 is built for the listed Chevrolet Blazer and GMC Jimmy rear glass applications and is designed to meet the dimensional and force requirements of those vehicles.
