PRT Shock Absorber Product Line Details

The PRT Shock Absorber line focuses on delivering dependable suspension components tailored for specific vehicle applications.

Technical Description and Features

This suspension shock absorber features a compressed length of 14.25 inches and an extended length of 22.28 inches, providing an 8.03-inch travel length and shock stroke. The gas-charged design helps maintain consistent damping performance under various driving conditions. The shock absorber includes a metal dust shield to protect internal components from debris and extend service life. Mounting is facilitated by a bolt-type upper mount and a loop-type lower mount, with measurement points centered on the bolt and loop respectively. The 1.77-inch body diameter supports structural integrity without adding unnecessary bulk. This shock absorber is non-adjustable and does not include coil over springs or a protective boot.

Applications and Problem Solving

  • Restores proper suspension damping for Buick Impala, LaCrosse, Regal, and Chevrolet Malibu models
  • Reduces excessive bouncing and improves ride stability
  • Minimizes noise and vibration caused by worn shocks
  • Protects suspension components from dust and debris with metal dust shield
  • Maintains vehicle control during braking and cornering

Installation Notes and Tips

Ensure compatibility with your specific Buick or Chevrolet model before installation. The upper mount uses a bolt connection, and the lower mount uses a loop, so verify mounting points for proper fit. Since this shock absorber is non-adjustable, no tuning is required post-installation. Inspect mounting hardware and suspension components for wear during replacement to ensure optimal performance.

Quality Assurance

The PRT Performance Ride Shock Absorber 373319 is manufactured to meet OEM specifications for fit and function. The gas-charged design and metal dust shield contribute to durability and consistent performance. Warranty information is not specified but typically aligns with industry standards for suspension components.
