Ground-pounding horsepower. Blown engines. Diesel power. The best in pulling battle it out at Madera Speedway for two unforgettable nights of competition.
Invitation Only

Why Madera?
Bringing it home.
For more than 50 years, the Massetti family has been part of truck and tractor pulling. Today, MLM Motorsports promotes events throughout California and Nevada — but GSI is special. It's our opportunity to bring the sport home to Madera and showcase our community to competitors and fans from across the West and beyond.
