KYB 565085 Shock Absorber - Rear

KYB MonoMax Rear Shock for Toyota Trucks

The KYB MonoMax 565085 is a heavy-duty rear suspension shock absorber built for Toyota trucks and SUVs that carry extra load, tow, or see rough road use. Its monotube construction and large-bore design are aimed at improving control, stability, and fade resistance in demanding conditions.

Key Features

• Heavy-duty monotube shock absorber for rear suspension use
• Up to 40% more damping performance than standard shock absorbers
• Large-bore design for added stability on higher center-of-gravity vehicles
• Zinc-coated stainless steel piston ring for sealing in extreme conditions
• Rubber dust boot helps protect the shaft and seal area from dirt and debris
• Engineered to work with vehicles equipped with electronic safety systems such as ESC and ABS

Product Details

KYB MonoMax is the truck-focused line within KYB’s shock absorber range, built for drivers who need firmer control than a standard replacement shock can provide. Part number 565085 uses a monotube layout that helps maintain consistent damping under load, while the work-ready piston ring and dust boot support durability in off-road, towing, and hauling conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 1995-2004 Toyota Tacoma, rear; 1984-1995 Toyota Pickup, rear; 1988-1990 Toyota Land Cruiser, rear; and 1984-1989 Toyota 4Runner, rear. Fits Toyota Tacoma rear lift replacement shocks with 0-2 in. lift, Toyota Pickup rear lift replacement shocks with 0-2 in. lift, Toyota Land Cruiser rear lift replacement shocks with 0-2 in. lift, and Toyota 4Runner rear lift replacement shocks with 0-2 in. lift.

Common Uses

• Rear shock replacement for worn or leaking Toyota Tacoma, Pickup, Land Cruiser, or 4Runner shocks
• Improving rear suspension control on lifted Toyota trucks with 0-2 in. lift
• Reducing bounce and instability when towing a trailer or hauling cargo
• Restoring damping performance after shock fade from off-road or heavy-duty use
• Supporting more controlled handling on vehicles with higher load demands

Installation Notes and Tips

Verify compressed length, extended length, and stroke length against the vehicle’s rear suspension travel before installation. Confirm upper and lower mount types match the existing hardware and inspect surrounding bushings, mounts, and fasteners for wear before replacing the shock. This rear shock absorber is intended for the listed Toyota applications and lift range only.

Quality Assurance
