MonoMax Product Line

KYB MonoMax is the brand’s heavy-duty truck-focused line for drivers who need firmer control than a standard replacement strut can provide. The line is built around monotube shock technology and is commonly selected for Toyota Tundra front suspension upgrades where load stability and consistent damping matter.

Detailed Description

KYB part number 561002 is a front suspension strut for 2007-2021 Toyota Tundra models. It uses a large-bore monotube design to support heavier, more powerful, or higher center-of-gravity trucks, helping maintain control during towing, hauling, and off-road driving. The work-ready piston ring and protective boot are intended to support durability in harsh environments, while the design is tuned for fade-resistant performance during repeated suspension movement. This part cross-references Toyota OE numbers 4851009Q90 and 4851009R20 for the same application.

Common Uses
