The weak spot in the driveline of the older Mopar is the axles. They can handle a slightly built up engine, but if you’re really building massive power, you need to install new axles.
Installing new axles in Ford’s venerable nine-inch rear end provides an inexpensive way to give your vehicle one of the best rear ends to come from an auto manufacturer.
Modified racer and champion Brett Hearn is developing some products for Strange Engineering’s oval track department, Strange Oval. He’s at the Volusia County Speedway with his No. 22 pro car giving a testimonial about the axles, torsion bars, and other products. Check out the cool, driver’s eye race shots as these Modifieds hammer their way around the track.
We’ve gone through engine sizes and mods for your strip burner. We’ve discussed the pros and cons of the different types of fuel delivery systems. We’ve even discussed transmissions for your strip burner. The last thing we need to talk about is the differential, also known as the rear-end.
