DMI EZIMCA4.12-PRO Details

BullDog has always tried to make things as easy as possible. When IMCA legalized quick changes they took the opportunity to create two rears to simplify the ordering process, these rears are the same high-quality CT-1 rears - just without tubes. The Saturday Night Special is the rear geared to the no-frills racer, while the Professional Series features the most popular options chosen by racers looking to leave no stone unturned. Either rear is more than capable of winning the IMCA Super Nationals!

This complete quick change rear axle without tubes includes 3 quarts of high-performance BullDog Blood Gear Oil

The EZ Series of rears have been overtaking the closed tube rear market over the last three seasons. The innovative time saving design benefits touring professionals and weekly racers alike. The modular concept offers superior strength, unmatched versatility, and simplifies tube replacement.

Unmatched Versatility:

Want to try a different tube? Is a tube swap required to comply with a different sanctioning body's rule? Loosen the nuts, remove the tube and install the new tube in under ten minutes. The spare tube can be a complete assembly. Brakes, hub, and birdcage can be mounted prior to tube swap. So easy a caveman can do it!

Simple Tube Replacement:

The rear does not even need to be removed from the car. The rear is sealed in the side bell. When the tube assembly is removed it is a dry process. No more fighting with a large bell at the press removing the old tube. Press availability an issue? No problem. Carry a spare tube and collar assembly and get back on track... fast!
