2014-2021 Toyota Tundra Pulleys

Serpentine belt slip, accessory drag, and the parasitic load the factory pulley ratio puts on the second-gen Tundra's engine are what 2014-2021 Toyota Tundra Pulleys address through underdrive configurations that spin accessories at a lower ratio and free up horsepower that the factory setup was spending before the driver asked for it. The improvement is real and the installation is bolt-on.

 

Lightweight billet aluminum crank pulleys on the second-gen Tundra reduce rotating mass at the source — the crank pulley is the largest and heaviest in the accessory drive system, and reducing its inertia is where the biggest gain in engine responsiveness comes from. Pulley kits that include both the crank and accessory pulleys as a matched set produce a more consistent underdrive ratio across the whole system than mixing individual pulleys from different manufacturers, and coordinated kits are available for the Tundra's 5.7L in configurations that keep the alternator at sufficient output for the electrical load the truck carries.

 

Crank and accessory pulley kits that free up power on the second-gen Tundra are what 2014-2021 Toyota Tundra Pulleys cover.
