Nascar Releases Solution For Broken Prop Shaft Issue

Chevrolet’s racing division completed its investigation into the issue that caused the propeller shaft on Tyler Reddick’s No. 8 Camaro to fail at the Clash at the Coliseum. Its findings prompted Nascar to release a solution that will hopefully prevent a similar malfunction from happening in future races.

According to Bob Pockrass, Nascar reporter at Fox Sports, the sanctioning body changed the transaxle mount from 1/4-inch thick to 3/8-inch thick. In theory, this should lessen excessive vibration, and therefore prevent the prop shaft from breaking, Pockrass stated in a Twitter post.

The failure occurred while the race was under caution. Reddick was leading when the yellow flag flew, and while the field was slowed, he wove his No. 8 Next Gen Camaro back and forth to build heat in his tires to prepare for the race restart. However, it became evident that the No. 8 had suffered a mechanical issue as it suddenly fell off the pace and slowed on the quarter-mile temporary track before the green flag waved. Reddick’s Camaro had to be pushed to the infield due to the sudden loss of drive power.

In the same caution period, the No. 14 Ford Mustang of Chase Briscoe experienced a driveline failure that appeared strikingly similar to Reddick’s issue. It was later confirmed that the No. 14 had also suffered a broken propeller shaft resulting from unprecedented stress on the race car’s transaxle under race conditions.

Nascar has made the updated transaxle assembly available to teams for use in the upcoming Daytona 500, which will take place on February 20th.

  1. How long has this car/driveline been in development and it fails in the first race multiple times?

    1. It will be interesting to see what else fails at Daytona. Evidently the development program was not very stringent.

  2. Todays drivers couldn’t handle the true stock car of the past, back then you had to see over the steering wheel 😉You had to manhandle the car and had to behave to strong arms !! All on bias-ply truck tires 💪

  3. ITS NOT NASCAR ANY MORE THERE ARE NO PRODUCTION CARS THAT HAVE ONE HUB NUT WHEEL AND THOUGHT IT HAD TO BE A 3200 LBS CAR ORG. LAST TIME I CHECKED A CAMARO,MUSTANG, AND THERE WAS NO V8 CAMERY EVER BUILT THAT I KNOW OF AND NEVER HAS WEIGHED 3200LBS
    I WOULD RATHER GO WATCH A LOCAL RACE THAN SPEND MONEY ON THIS CRAP

  5. Wish the terminology would go to drive shaft versus propeller shaft. This is not a marine environment. A propeller is a circular part that is shaped and profiled for forward and reverse movement in watercraft and ships.

  6. Seems the propshaft held up in the Daytona 500, but there were a few cars which the rear setups were broken due to spins & wrecks. More so than with the old pan hard set-up. And those fancy aluminum wheels & Single nut attachment, Also presented problems. Just a lot of New things, to be worked out. There will probably be some changes to add Stability to the cars too!
