As has been shown, the 2015 Mustang’s stock halfshafts will need to be upgraded if you are a serious drag racer.
G-Force Engineering shared with Mustang6G the story of how Ford Racing approached the company last year at the Performance Industry Trade Show to begin testing its halfshafts and evaluating its use on the new S550 Mustang platform.
Ford Racing and G-Force began spending weekends at the race track helping Ford test the G-Force axles and logging hundreds of drag strip launches, including the same ones shown in Ford’s now well-known .99 Challenge videos.
G-Force reports that the team would tear down the halfshafts for inspection after every hundredth pass, looked brand new after 300 hundred passes, and that nobody has ever snapped a G-Force Level 5 Outlaw halfshaft with 31 spline axle bars and cv center stars.
Of course, the aftermarket is all about choices and the Driveshaft Shop also shared with us the research and development that went into its 800hp and 1400hp axles:
“First we started with both the inner and outer splines going into the Hub and the Differential. We have been working with Ovaco steel out of Sweden and they came up with a material called Ovaco 300 that has been used by DSS in each and every IRS/CV driven world record breaking car to date (includes Mark Carlyle’s amazing Vette running 6.82 with a 1.1 60ft time and many other cars in the 7’s ,8’s and 9’s also). So each spline is now made from this amazing 300m material (on both the 800HP and the 1400HP versions).
We then made 4340 billet CV mounts and are using our proven 108mm CV with full 300m Billet Chromoly cages and races (with the 1400HP axles using the larger 30 spline bars). This along with Neo HPCC1 grease and with a higher durometer Neoprene boot, it will handle just about anything you can put to it.
We didn’t stop there, the center bars we made are done with our CNC spline rolling process, which most people “in the know” will tell you that a rolled spline is significantly stronger than one that was done with material cut away because it is actually forging the spline and compressing the micro structure to make it even stronger.”
