Max-Air Air Shock Absorber Product Line Details
The Max-Air Air Shock Absorber line by Monroe is designed to deliver consistent air suspension support for light trucks and SUVs. This product line focuses on maintaining proper ride height and load control, which is critical for vehicles like the Ford Ranger and Mazda B-series trucks. The MA770 model integrates features such as extended hydraulic lockout exclusion and durable rubber dust shields to enhance longevity and performance under varying load conditions.
Technical Description and Features
The Monroe MA770 air shock absorber features a compressed length of 15.875 inches and an extended length of 26.375 inches, providing a travel length of 10.5 inches. It includes both compressed and extended bumper stops to protect the shock absorber during full compression and extension cycles. The rubber dust shield safeguards internal components from dirt and debris, extending the service life of the shock. The upper mounting uses a loop bushing mount with a 5/8 inch bushing inner diameter and 1.5/16 inch outer length, while the lower mounting employs a loop bushing and sleeve mount with a 12mm sleeve inner diameter and 1.5 inch outer length, ensuring secure and precise fitment on compatible vehicles.

When installing the Monroe Max-Air Air Shock Absorber MA770, ensure the vehicle is securely lifted and supported.

Avoid forcing the shock absorber beyond its travel length of 10.5 inches to prevent damage. Proper alignment during installation will help maintain suspension geometry and performance.
