KYB 565120 Shock Absorber - Front

KYB MonoMax Front Shock Absorber for Ford Trucks

The KYB MonoMax 565120 is a front suspension shock absorber built for Ford trucks and vans that need firmer control under load. Its monotube construction, large bore design, and dust protection are aimed at drivers who tow, haul, or run heavier-duty applications.

• Up to 40% more damping performance than standard shock absorbers
• Zinc-coated stainless steel piston ring for sealing in demanding conditions
• Rubber dust boot included to help keep dirt and debris away from the shaft seals

What This Shock Helps Address

• Reduced control when towing or hauling heavy loads
• Front suspension fade during repeated rough-road use
• Dust and debris exposure around the shock shaft and seals
• Need for a monotube upgrade on select Ford truck and van applications

Installation Notes

Verify mount style, compressed length, extended length, and stroke before installation. This shock is listed for front position use only, and fitment varies by model year and suspension package. Confirm whether the vehicle has off-road suspension or motorhome chassis exclusions where noted in the fitment data. Part number 565120 should be matched to the vehicle application before service.
