Product Details

Monroe Max-Air MA822 is part of the Max-Air Air Shock Absorber line, a product family focused on rear suspension control for vehicles that need extra support under load. This unit is commonly selected for towing and hauling applications on Buick, Cadillac, Pontiac, Oldsmobile, and related GM full-size sedans, including the Buick Lucerne, Cadillac DTS, Buick LeSabre, Buick Park Avenue, Cadillac DeVille, Pontiac Bonneville, Cadillac Seville, Oldsmobile Aurora, and Buick Riviera. For vehicles originally equipped with non-air suspension, an AK29 kit is required when adapting air struts to that setup. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number MA822 is also referenced by interchange numbers including KYB SR1002 and SR4116.

Common Uses

• Rear sag when carrying cargo or towing a trailer
• Loss of ride height after adding weight to the vehicle
• Need for adjustable rear suspension support on GM sedans

• Replacement for worn rear air shock absorber applications
