Rev Limiter?

Do these trucks (04.5 mine specifically) have a built in rev limiter, so dummy's like me won't over rev?

Yes, they defuel by 3200 RPM, so the only way to overspeed them is by downshifting to the wrong gear at high speed.

The Cummins is rated to turn 3500 RPM 24-7 for industrial applications.
