Genuine Massive Speed: Precision Crank Bolt Kit for GM LS7 / LS9 / LS3 Dry Sump V8 Engines

All OEM Dry Sumped LS motors - Corvette LS3 Grand Sport, LS7, LS9, ZR1, Z06, Camaro Z/28

  • 2006-2013 Corvette Z06, Z06 Carbon, 427.

  • 2010-2013 Corvette Grand Sport with Manual Trans Dry Sumped.

  • 2012-2015 Camaro Z/28

Truly superior strength is needed on this most critical of load bearing fasteners. The crankshaft sees immense kinetic energy! Both twisting and lateral loads are exerted on this one area, and to an even greater degree on belt driven supercharged cars.

OEM fasteners are one-time-use - they stretch and must be replaced, so upgrading with the Massive Speed Precision unit is a "no-brainer". Grade 12.9 197,000 PSI tensile strength 12 point flanged bolt finished in black oxide places superior clamp only load to balancer through the use of a seperate washer plate (a full 1/4" thick!).

Fully reusable. Will not fit regular LS motors - see our other listings. Crank bolt should never be used to install balancer, use of proper tool is necessary.

These are every bit as strong as the other guys, but priced right, and IN STOCK!!!

Made right here in the USA!!!

NOW INCLUDES Genuine ULTRA-TORQUE Moly Assembly Lube!!! The other guys DON'T Include it!

Better than expected!
After reading the reviews about it being oversized, I was able to get the right fit that I wanted. It is on the thinner end as far as sweatshirts go, but I tend to run hot so I was quite pleased that I got a long sleeve shirt that didn’t make me sweat. Now, let me tell you about the quality …. For some reason I thought the design was just printed on it, but it’s not! The “jolly” is sewn on, and the stripes don’t look cheaper. I love the red banding at the neck, sleeves and waist. It’s so comfortable, and I got compliments on it all night. I would definitely buy it, or any of their own sweatshirts, again!

Runs big. Fabric is nice. Love the color
It's a nice color of green and feels great. I ordered a medium due to the reviews. It's a larger than a normal medium so it's slightly too small. I usually wear XL and sometimes L. So, it does run big. I returned it but probably will order a L.
