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!

Exact fit, no trimming needed
Style: One Piece
Ordered this for my Ford F-150 and it dropped right into the airbox perfectly — same dimensions as the OEM filter, same end seals, same fit. No gaps, no air bypass around the edges. Clean swap in under five minutes. Engine runs smooth and the price is unbeatable.

Great plug
Style: Single
My car goes through these every 30,000 miles or so. But fantastic plug all around. Performs flawlessly even at almost 9000 rpm.
