Watch Team Jegs Change The Ratios In A Pro Stock Transmission In Minutes

We don’t call ourselves BANGshift for nothing. We’re all about clutch pedal racing whenever possible, and that means NHRA Pro Stock is our jam. Now whether you like them or not you have to admit that 500 cubic inches screaming at 10,000 rpm while rowing gears is pretty badass. Yes the transmissions are clutchless for shifting, but that’s because they are designed specifically to be able to be shifted without ever lifting off the throttle, regardless of engine rpm. When you see inside one you’ll understand why. One thing you may not know about a Pro Stock transmission is that it comes apart easily for gear ratio changes. The teams don’t change the high gear ratio, but they often change the lower gear ratios in order to take advantage of track conditions or power based on the weather conditions and density altitude.

Thanks to the wonders of a chest-mounted GoPro, you get to watch the Jegs team take one apart, change the ratios, and put it all back together. In real time it takes just 5.5 minutes. MINUTES! And while the guy in the video is clearly working quickly, he is not running around like a crazy person trying to finish as quickly as humanly possible. If that was the case I’m sure he could do it in under 4!

This is cool stuff to watch.
