SKP SK6402 Suspension Trailing Arm - Rear

Rear Suspension Trailing Arm for GM Applications

The SKP SK6402 is a rear suspension trailing arm for a wide range of Chevrolet, Buick, Pontiac, and Oldsmobile applications. It is listed for rear fitment on vehicles such as the Chevrolet Impala, Chevrolet Monte Carlo, and Buick Regal, with coverage that spans multiple model years and suspension packages.

Key Features

• Rear suspension trailing arm for direct replacement use.
• Fits applications with FE1 Soft Ride, FE2, and FE3 suspension notes where listed.
• Coverage includes select Chevrolet Impala, Monte Carlo, and Lumina models, plus Buick, Pontiac, and Oldsmobile applications.
• SK6402 part number for easy identification and ordering.

Detailed Fitment Overview

Compatible With rear suspension applications across 1988-2016 GM passenger cars, this trailing arm is listed for the Chevrolet Impala Limited, Chevrolet Impala, Chevrolet Monte Carlo, Chevrolet Lumina, Buick Allure, Buick LaCrosse, Buick Century, Buick Regal, Pontiac Grand Prix, and Oldsmobile Intrigue and Cutlass Supreme. Fitment notes vary by vehicle and suspension package, including FE1 Soft Ride Suspension, FE2 Suspension, FE3 Sport Suspension, and select applications that include bushings or exclude the police package.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The SK6402 is a practical replacement for worn rear trailing arm assemblies on Chevrolet Impala and Buick Regal platforms where rear suspension geometry and ride control are affected by age or wear.

What It Is Used For

• Restoring rear suspension alignment after trailing arm wear.
• Reducing looseness, clunking, or instability from a fatigued arm.
• Replacing a bent or corroded rear suspension link.
• Addressing ride and handling issues tied to worn rear suspension bushings.

Installation Notes and Tips

Verify the exact year, model, and suspension note before ordering, since several applications require FE1, FE2, or FE3-specific fitment. Match the rear position and confirm whether your vehicle listing calls for bushings or a specific exclusion such as the police package. Professional installation and a post-repair alignment are recommended after replacing rear suspension components.

Quality Assurance

SKP replacement suspension components are cataloged for application-specific fitment, and the SK6402 part number helps ensure the correct trailing arm is selected for the intended GM platform.
