Keep your truck planted under heavy loads with the Monroe Magnum Severe Service 550064 2007-2021 Toyota Tundra shock absorber, a rear suspension unit built for emergency, municipal fleet and construction use. It installs as a direct-fit replacement for the 2007-2021 Toyota Tundra (rear position). These gas-charged, extra-durable Monroe shocks use strengthened components for stability and ride control in the toughest applications, with a larger bore for greater working capacity and arc-welded mounts for higher tensile strength.
Severe Service construction: Loop welding technique provides up to 14,100 lbs. (6,395 kg) tensile strength; the 1-3/8-inch (35 mm) bore and 2-inch (50.8 mm) reserve tube deliver more efficient, consistent control (on most applications).
Nitrogen gas-charged: Helps maintain tire-to-road contact by reducing aeration for improved ride and handling.
Durability features: A robust hydraulic lock-out prevents over-extension and top-out, while a PTFE-coated bearing reduces friction between the rod and rod guide, and Tenneco shouldered bushings resist bushing walkout (on most applications).
Controlled response: 10-stage valving reacts to a wide range of driving conditions (on most applications).
Sold individually, so this listing is for one shock; replacing both rear units together is recommended for balanced ride control. See the Buyer's Guide tab for engine-level fitment.

This part cross-references / interchanges with the following part numbers:
Does the Monroe 550064 fit my 2007-2021 Toyota Tundra?
Yes. The 550064 is designed as a direct-fit rear shock absorber for the 2007-2021 Toyota Tundra. Check the Buyer's Guide tab to confirm the exact application for your truck.
What position does this shock absorber mount in?
This is a rear suspension shock absorber.
What makes this a Severe Service shock?
It's engineered for emergency, municipal fleet and construction use, with strengthened components, a larger bore for greater working capacity, and arc-welded mounts for higher tensile strength.
Is this shock gas-charged?
Yes. It is nitrogen gas-charged, which helps maintain tire-to-road contact by reducing aeration for improved ride and handling.
Should I replace both rear shocks at once?
Replacing both rear shocks together is recommended so the ride control stays balanced side to side. This listing is for one shock absorber.
