Lightweight or High Torque — This Is the Whole Decision

Everything else on this page follows from one choice, and it is not "which is better." It is what the truck does.

  • Lightweight removes rotating mass, so the engine picks up and drops revs faster. It makes a small engine feel eager and a manual gearbox feel sharper. It also makes the truck easier to stall, less pleasant to creep in traffic, and harder work on a steep loose climb, because there is less stored energy to carry you through.
  • High torque is heavier than stock. It holds momentum, which is what you want with a trailer, a loaded bed, or low-range crawling. It will feel slightly lazier to rev on the road.

A daily-driven trail truck is usually better served by high torque. A light, mostly-street 22R that has been built for revs is the case for lightweight.

Pro Clutch and Flywheel Bundle Kits

The flywheel and the clutch have to suit each other — clamp load, disc material and flywheel mass are one system, not three purchases. These are matched sets, and they are the easier way to buy if you are replacing both anyway, which you usually should be.

Before You Order

  • Fitment follows the engine and bellhousing, not the truck. This is why the page is organised by engine code. If the engine has been swapped, go by what is in it now.
  • Check the clutch diameter. The 2RZ appears twice for a reason — 9 1/4" and 10" are both correct depending on the setup, and they are not interchangeable.
  • Replace the rear main seal and the pilot bearing while you are in there. Both are inexpensive and both require the gearbox out again if you skip them.

By Engine Platform
