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!

Great for bored dogs
Color: Flip Board, Size: Level 2
Great dog puzzle! My pup loves this, he did chew the peg portion once he got them out so they can be put back in. They are tough for small dogs to get out so I think he plotted it out.

Actually Holds up
Color: Knuckle Bone, Size: XX-Large
I must say I had low expectations when buying this bone based on prior experience of similar products. I'm happy to say I was pleasantly surprised. I bought this bone off Amazon in the beginning of December, I wanted to wait a while for my review to see if it would actually hold up. So far so good. There are several factors that set this bone above similar products. First let me be clear that this is the Beef bone not the chicken etc. (I'm told there is a huge difference) 1. The first thing that impressed me is that my dog actually loves to chew on it. I know this may sound weird but I tried the puppy pack of nylabones and a bit larger one. He was interested in them but it didn't last and he wouldn't touch them anymore. This bone on the other hand is his absolute favorite. He carries it around everywhere. Even though it's beef flavored it doesn't have a noticeable smell or residue and it doesn't get slimly like a real bone. 2. This bone is extremely durable. I have a chew happy 10 month old lab puppy with razor teeth and majoring chewing skills. Trust me, my ruined shoes are proof :) It's been almost two months and I can just see where the bone has worn down. The down side to this is it is extremely heavy, not ideal to be leave around to step on, especially because of the way the bone breaks down. As they chew on it is almost peals away into tiny, tiny chunks. This is great compared to a kong stick that he had where he was swallowing large pieces of a rubber/plastic material. The downside is that as it "peals" it leaves the bone very sharp, with little spikes around where they chew. So far my dog doesn't seem to mind and it doesn't seem to make his mouth bleed or anything so that's a minor negative. Just don't stub your toe on it! Trust me! Overall after trying multiple brand/types and flavors this is the only one that gets my seal of approval.

This is a great option for tough chewers
Color: Knuckle Bone, Size: XX-Large
This is a great option for tough chewers, although if your dogs are anything like ours, there is a procedure to ANY new toy no matter how "tough". If I gave them this Nylabone and they went unsupervised day one, they would wreck it and it'd be in the trash within the hour. I say this to tell you, if you have a top 10 bite strength aggressive chewer, that you shouldn't expect a miracle. If instead, I give it, take it away when they are working it too hard or being particularly destructive, and then give it back- and do this a few times for a week or so, then they'll chew it in a less aggressive fashion- they'll enjoy it and it lasts a long time. I don't know what it is about the first few days, but when something is "new" it has to be destroyed. When it's been in the house a few days, they are rough but not as bad. Like the ones listed "virtually indestructible" will last 6 months as long as we have multiple around. It will show damage, there will be shrapnel in the carpet that will scratch up your feet, but it'll be worthy of play still. I consider 6 months in our house worthy of 5 stars. This has been true for 2 Dobermans and a German Shepherd- and all of them have proven ability to destroy these products day 1 if I don't behave appropriately on introducing the new toy. If your dog wrecks these in the first 10 minutes, I'd say you probably need to work on supervising new toy play, and taking it away when they become to aggressive. This is a training issue, it can be done!

Lasting longer than 6 months, longer than any bone to date.
Color: Mega Knot Bone, Size: X-Large
Finally a bone that has lasted longer than 6 moths so far. I know my dog is a chewer. Well worth the cost to not have to replace them as often.
