Perfectly balanced power for today’s truggies!
With input from top truggy drivers, O.S. has developed the ideal engine for these hybrid hot rods! The 28XZ produces more low-end torque, providing the rpm/torque balance that heavier truggies require. The result is power that’s incredibly smooth, for truggies more drivable than ever thought possible!
• The larger head aids in cooling, and is a 2-piece construction with inner head button.
• A sealed front bearing and high-performance inner bearing are part of the new crankcase design.
• The high-performance con rod features oiled bushings.
• Three needles enhance fine-tuning on the 21J slide-valve carb.
• Comes with a high-performance P3 hot turbo plug. |
