Rancho RS77759 Suspension Strut - Front

Rancho RS7MT Front Strut for Tundra

The Rancho RS7MT monotube front strut is built for 2007-2021 Toyota Tundra applications that need controlled on-road response and consistent off-road damping. Part number RS77759 is tuned for front suspension use and is suited to trucks running larger wheel and tire packages.

RS7MT Product Line Details

Rancho RS7MT struts use a single-tube monotube design to help dissipate heat during demanding driving. The line also includes an integrated dirt wiper sealing system, a hardened piston rod for improved resistance to scuffs and corrosion, and an internal rebound bumper to smooth suspension movement across changing terrain.

Detailed Description

RS77759 is a Rancho RS7MT front suspension strut for the Toyota Tundra, covering 2007-2021 model years in the front position. Its monotube, gas-charged design is built to manage heat effectively, which is important for trucks that see repeated suspension movement, heavier wheel and tire setups, or mixed pavement and trail use. The stem upper mount and loop bushing lower mount support direct fitment for the listed application, while the internal rebound bumper helps reduce harsh extension over uneven surfaces. This part cross-references KYB 551125 and 561002 for the same application.

What This Strut Helps Address

• Excessive front-end bounce on rough roads
• Reduced control during off-road driving
• Heat buildup from repeated suspension cycling
• Wear concerns tied to larger wheel and tire packages
• Corrosion and scuff exposure on the piston rod

Installation Notes and Tips

Verify front suspension fitment against the listed Toyota Tundra years before installation. Confirm the stem upper mount and loop bushing lower mount match the vehicle’s existing hardware and inspect surrounding suspension components for wear before replacing the strut. Because boot and dust shield are not included, reuse or replace those items as needed based on condition.

Quality Assurance

Rancho RS7MT struts are built as performance-grade suspension components with a monotube design, hardened piston rod, and integrated dirt wiper sealing system for demanding truck use. Part number RS77759 is engineered for the specified Toyota Tundra front application.
