Monroe Max-Air Shock Absorber MA805

Monroe Max-Air Shock Absorbers MA805 are specialized air-adjustable shocks designed for vehicles that face varying load conditions, such as work trucks, passenger vans, and vehicles frequently used for towing. These shocks function as a heavy-duty helper system, allowing the driver to inflate or deflate the internal air bellows to maintain a level ride height regardless of the payload.

By integrating a pneumatic chamber with a high-quality hydraulic shock, the Max-Air system prevents rear-end sag and "bottoming out." This is critical for maintaining proper suspension geometry, which ensures that steering, braking, and headlight aim remain consistent even when the vehicle is loaded to its maximum capacity.

Features of the Monroe Max-Air Shock Absorber MA805:

• Air-Adjustable Damping: Can be inflated between 20 psi and 150 psi to compensate for extra weight (up to 1,200 lbs per pair).
• Large Volume Air Chamber: Provides additional support without hardening the ride when the vehicle is empty.
• Hardened Chrome Piston Rod: Precision-ground for consistent performance and long-term seal durability.
• All-Weather Fluid: Contains special modifiers to handle extreme temperature fluctuations without losing damping consistency.
• Lubricated Air Sleeve: Reduces friction between the air bag and the shock body for smoother operation and a longer service life.

Benefits of the Monroe Max-Air Shock Absorber MA805:

• Eliminates Rear-End Sag: Keeps the vehicle level when towing trailers or hauling heavy equipment, improving overall stability.
• Improves Braking and Steering: By maintaining the correct weight distribution, it ensures the front tires keep maximum contact with the road.
• Customizable Comfort: Allows the driver to adjust the "firmness" of the rear suspension based on the specific task at hand.
• Protects Other Suspension Components: Prevents leaf springs and bushings from being over-stressed during heavy-load cycles.
• Direct Bolt-On Fit: Designed to replace factory shocks using existing mounting points, with an easy-to-install air line kit usually included.
