Max-Air Air Shock Absorber Product Line Details

The Max-Air Air Shock Absorber line by Monroe is designed to enhance suspension systems by integrating air spring technology with traditional shock absorber functions. This combination allows for improved load handling and ride control, particularly useful for trucks and SUVs that carry variable cargo weights. The MA812 model fits specific Mazda, Mitsubishi, and Nissan vehicles, providing a tailored suspension solution within this product line.

Technical Description and Features

The Monroe MA812 air shock absorber features a compressed length of 12.75 inches and an extended length of 20.75 inches, offering an 8-inch travel length to accommodate suspension movement. It includes a rubber dust shield that protects internal components from dirt and debris, extending the service life of the shock. The compressed bumper stop helps absorb impact forces during compression, reducing wear on the suspension system. Both upper and lower mounts use loop bushing mounts with precise dimensions (5/8" bushing ID x 1.5/16" bushing OAL) to ensure secure and proper installation.

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before removing the old shock absorber. Verify that the upper and lower mounting points correspond to the loop bushing mount specifications (5/8" bushing ID x 1.5/16" bushing OAL). Inspect mounting hardware for wear and replace if necessary. The included rubber dust shield should be positioned correctly to protect the shock absorber shaft. No extended bumper stop or hydraulic lockout features are present on this model, so standard installation procedures apply.
