The Carmack, Chrisman, and TSP Racing rear ends offer all suspension, shock, and wheelie bar mounting points to incorporate the housings into a current doorslammer tube chassis without modifications to the cars themselves.
Steve Chrisman is also pleased with his rearend when it comes to doorslammer racing.
-------------------------------------------
“Our first rears were an effort between
Larry Jeffers Race Cars and us. The first unit was installed in Randy Merick’s Pro Modified Corvette. He was throwing gear sets away after just two to four passes. With our 11-inch differential in there, they have 15 passes on it already and haven’t even looked at it yet. Similar to the typical Top Alcohol Funny Car, the Pro Modifieds can see 25-30 runs on them without a problem.”
Another testimonial to the new differential designs, Steve Ham describes how one of Australia’s quickest Pro Modifieds, the Moits Racing Mustang has put over 80 passes on his original gear set and bearings.
The old saying that “the only thing constant is change” definitely applies to all of motorsports, especially with the ever-increasing horsepower numbers coming from supercharged, nitrous, and turbo-boosted doorslammer. With that increase in power, count on the world of hardware engineered for use in everything from nitromethane to extreme door cars to continually evolve. As quickly as companies can design and machine stronger hardware, the war will continue between horsepower and the sticky dragstrip surface.
