BullDog has always prioritized convenience, and when IMCA legally allowed quick changes, they seized the opportunity. They created two rear options to streamline the ordering process - both featuring their renowned CT-1 quality without tubes.

The Saturday Night Special is perfect for no-frills racers, while the Professional Series offers the most popular options for those wanting to leave no stone unturned. Either rear is more than capable of dominating the IMCA Super Nationals!

Not only does this complete quick change rear axle come without tubes, but it also includes 3 quarts of high-performance BullDog Blood Gear Oil and EZ Bells side bells.

In the last three seasons, the EZ Series of rears has overtaken the closed tube rear market. This innovative design saves time and benefits touring professionals as well as weekly racers. The modular concept provides exceptional strength, unparalleled versatility, and simplifies tube replacement.

By incorporating shallow aluminum side bells, the side bell rigidity is increased by nearly 75%! Reduced flex leads to improved traction. The heavy duty tube collars maintain their straightness and integrity even during severe crashes. The tubes are securely fastened to the bell using (6) Grade L9 hardened 7/16" studs. Additionally, the EZ system adds 8 lbs to the total weight of the unit.
