O.S. Engine 28XZ Truggy Engine   [OSMG2074]

With input from top truggy drivers, O.S. has developed the best engine for these hybrid hot rods! The 28XZ creates more low-end torque, supplying the rpm/torque stability that weightier truggies need. The end result is power that??s incredibly smooth, for truggies more drivable than in the past thought possible!

The bigger head helps with cooling, and it is a 2-piece construction with inner head switch.
A sealed front bearing and high-performance internal bearing are the main new crankcase design.
The superior con pole features oiled bushings.
Three needles enhance fine-tuning on the 21J slide-valve carb.
Is sold with a high-performance P3 hot turbo plug.
The Mark Pavidas Edition Tuned Pipe (OSMG2969) may be the perfect accessory for the 28TZ; flywheel sets are needed (OSMG2648 for Mugen, OSMG2649 for Kyosho, both offered separately) for several truggy models.
