Your cart is empty.XL Series! 10mm extra length provides MORE thread engagement! Still fits ALL LS Motors '97- today except Dry Sump. Perfect for getting proper thread engagement on those DAMAGED crank snout threads!!! Did you (or someone else?) use a stock or other bolt to attempt to draw down the press fit crank pulley? Those who have tried this soon realize the first several threads will be pulled out of the crank... often rendering the crank useless. Massive has released this new XL-LS Extended length bolt that travels further into the threaded crank snout to engage more thread, giving your damaged crankshaft new life. The OEM bolt only engages the last 22mm of thread. Our new XL-LS bolt offers 32mm of engagement, a 50% increase. So even if the first few mm of your crank threads are damaged, merely clean out any material, and you will obtain proper or even increased thread bond! Others have used the superior torque transfer on their crank driven supercharged cars for enhanced clamp load. Our bolt is a full 10mm longer than the OE or ARP bolt. Because, who couldn't use an extra 10mm? Works with ALL LSX Engine (except LS7 or other OEM dry sump - see our othre listings for those applications). Grade 12.9 197,000 PSI tensile strength 12 point flanged bolt finished in black oxide is far stronger and places superior clamp only load to balancer through the use of a separate washer plate (a full 1/4" thick!) versus the 1 piece stocker. Fully reusable.

Hefty and solid. A dash of loctite on the threads and its good to go.

Quality parts. I bought this and another bolt they offer. The packet of ARP assembly lube was an unexpected surprise. Niiccee

This seems to be a quality product. I didn’t like the design of the bolt head. This bolt is compared to the ARP bolt, however this bolt has a much smaller bolt head than the ARP bolt. This bolt is longer than the ARP bolt as advertised.

fast delivery. only have about 1/2 hour of run time on the engine so far, seems to be holding the aftermarket balancer fine.

This is an updated Review. This product does not fit on my Engine but after several emails with this company they have brought to my attention that my engine might be a older model. This company has worked with me on this problem and even though I was past the deadline on returning this part. They have already issued a full refund. So my advice is to check the measurements of your bolt and make sure they match up. The measurements is listed on the page. To those who do have the right engine the bolt does seem to be made of good quality material.

If you're like me and are constantly rebuilding engines or like swapping parts with your buddies this Crake Pulley Bolt is a MUST! It's reusable so you don't have to be constantly buying one. I have used the OEM crank bolt and trust me once you feel it in hand you'll see how cheap it feels! This one feels very high quality and it's made in the USA!I am running this in a 612 HP LS1 engineGreat Stuff!

I was excited to get this in and use it on my motor as I was assembling a fresh rebuild. Unfortunately, I couldn’t even use it. It bottomed out the threads and still had 1cm of space before it would touch the stock harmonic balancer on my bone stock LS1. Therefore, it was useless for me and a waste of time and money as I had to just reuse the stock bolt.
