Want a little extra security that your N54 crank bolt won't back out leaving you with 24 bent valves? Here is an easy and cost effective way to do that; the VTT N54 crank bolt capture. It slips over the head of the crank bolt, fully encapsulating it, and locks it to the crank hub. This means the bolt cannot back out -no matter what.

The VTT-N54-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look.

While this is not a full fix for all crank hub spinning issues, we have found most of our issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely light weight at only 1.3 ounces, it adds virtually no weight to the crank which is important for balance and vibration purposes.

These are in stock, and on the VTT Website for immediate sale. Price is $99 for hub capture, and all 12.9 hardware needed for install. We suggest using blue loc-tite on your crank hub bolts. Note: First pics are of the N54 crank bolt capture; the last 3 pics are of the S55 crank bolt capture (different height/dims/8 bolts vs 6, etc. Those last pics were actually taken by a dealership who -under warranty- installed it on a customer's car who spun their hub. :)

Chris, would you attribute this to more tear downs/rebuilds VTT does than the average guy? As in, you guys are always experimenting, while the average guy probably has never touched his crank bolt. If a crank bolt hasn't backed out in 90k+ miles, what is the likelihood its going to come out now you know? Is it a HP thing or??? Obviously no one wants bent valves, just trying to determine the importance of this for my own setup.

It's happened to a handful of guys, but it isn't really common knowledge. We've heard of it from a dozen or so people, some guys had it happen after they did walnut blasting and used the crank bolt to turn the motor, some guys the engine just got higher mileage and it let go... we're not 100% sure. For us, it started with a crank bolt we thought was tightened from the machine shop and it wasn't. That was the original slip that screwed things up. Once we figured out those parts were now junk, when it happened again on good parts we realized the crank bolt itself was backing out. Captivating it then makes sense.
