Drive axles are subjected to immense torque loads. Simply multiply the engine torque by the transmission ratio and the ring-and-pinion ratio (torque x low gear ratio x rearend ratio), and you see that forces multiply rapidly. Read More...
Text by Bill Holland Posted September 19, 2019 on dragzine.com The venerable 9-inch rear end, originally offered in 1957-1987 Ford cars and light trucks, has been a staple of drag racing for over 50 years. Its beefy 9-inch ring gear proved to be an effective alternative to the 8-3/4 Mopar and GM 12-bolt (8.875-inch diameter ring gear) housings of the era, with other attributes also a factor in its popularity.

By Lindsey Fisher Dragzine.com Article The right driveshaft can mean success on the track as much as it can mean disaster. That is why it is so important to weigh the options when it comes to choosing a performance driveshaft for your performance vehicle. Read More...
By Wayne Scraba Muscle Cars Tech Article If you bought a new high performance passenger car from ford three to four decades ago, it definitely came with one rear end: a 9.inch. And if was a bona-fide ground pounding musclecar, that 9-inch was filled with 31-spline carrier and axles. Read More...
By Wayne Scraba Hot Rod Tech Article The Chevrolet 12-bolt rear axle is a prolific piece. It turns up in countless Camaros, Chevelles, Novas and full size Chevys. Although it may not be as popular as a 9-inch Ford in drag race applications, the 12-bolt does have a number of plusses (not the least of which is decent strength when carefully prepped). The other thing to consider is the shear volume of 12 bolts out there... Read More...
By Mark Houlahan 5.0 Mustang & Super Fords "Our main decision came down to the axlehousing. Do we keep an 8.8 under the rear of the Real Street car, or do we go with the respected but heavier 9-inch rear? Since our Real Street car didn't have a V-8 spec rear under it (heck, it didnt have any rear under it), we had to start from scratch." Read More...
By Henry De Los Santos Race Pages There are few things more exciting than the adrenaline rush of inching into the staging beams, matting the throttle against the two-step and waiting for the ambers to flash, in anticipation of rocketing your Mustang off the line to a 60-foot time that would make a Pro 5.0 racer jealous.

By Evan J. Smith Muscle Mustang & Fast Fords Nothing came easy in the early years of the 5.0 Mustang racing. Go-fast parts were limited to small blowers, nitrous, gears and not much else. Still, the EFI Mustang pioneers got by using age-old tricks to improve performance. As slicks went on and horsepower increased, elapsed times dropped into the 12s and then 11s, but all was not good in Mustang land. Read More...
By Wayne Scraba Drag Racing USA Remember the old story about a chain being only as strong as its weakest link? That same analogy applies to the drivetrain in your race car. One component that is often ignored is the wheel stud. The loads encountered by the wheel stud might be much larger than you think. Read More...
By B. Holland Hot Rod "Drive axles are subjected to immense torque loads. If this isn’t evident, multiply the engine torque by the transmission ration and the ring-and-pinion ratio (torque x low gear ratio x rearend ratio),and you see that numbers get prodigious way fast. And what’s on the receiving end of this force? The drive axles of a 1,300hp drag car must collectively withstand upwards of 12,000 lb-ft of torque every time the driver drops the hammer."
