FINALLY, a 6.4L Hemi Drop In Piston/Rod Kit!

Livernois Motorsports is proud to release it's brand new 6.4L Hemi Engine piston and rod drop in kit. This kit is designed and engineered to be a perfect fit for your existing 6.4L Hemi engine. The components are designed to exactly match the weight of the stock components, allowing the pistons and rods to be installed in the engine without having to remove or balance the crankshaft.

In addition to the built in balance of the components, the pistons have also been designed to be a perfect drop in fit for your existing 6.4L Hemi engine. The pistons have the appropriate piston to wall clearance built in, so all you need to do is install them, no machining of the block necessary.

This kit allows replacing the weak factory rods and pistons with heavy duty, custom engineered replacements, built for power adders, all without requiring any machining work on the block, or balancing of the stock crankshaft.

Kit includes the following-

Custom 6.4L Hemi Pistons (Built for boost, 2618 material, thicker ringlands, coatings, heavy wall pin)
Stainless Steel Ringset (Boost Ready)
H-Beam Forged Connecting Rods
Tri-Metal Performance Rod Bearings
 
While I don't have a Hemi myself, I think this is a great idea and wish that we'd see stuff like this more often on other platforms.
 

Thank you!

Good to know!

If you need any info just give us a shout. We will be more than happy to help!

It is not an easy feat. The Hemi is especially difficult because the rotating assembly for that motor comes in a few different configurations with varying weights and masses. So there was a lot of R&D that was involved in making this a viable solution for the guy that just wants a simple replacement without any maching.
 
What Piston to Wall will these give the end user??? Will one have to file the rings?? Whats the end gap on them??

Well thank you for your inquires Saso! That is going to vary slightly depending on the block. The variance is only going to be at most a couple thousandths. Which is fairly normal for the Hemi variants, as they even vary slightly from the factory. Our kit is 110% based off of the stock bore. As for the rings, we actually offer the kit fully assembled and even labeled so all that the end user has to do is drop each piston in the correct cylinder! It honestly could not be any easier!

Piston to wall clearance is going to end up around .0032-.0036, that's over the piston, the coating is not factored in. Rings are not ground, and will need to be ground to fit. Bearing clearances on the rods are not done and with any engine work, it's always suggested that you check your bearing clearance before assembly to ensure proper clearance. The rings and rod clearances can be accomplished far easier than the balancing and cylinder honing.

The idea is that the difficult portions of work, that most end users couldn't complete easily themselves, will be done, plus a large amount of work that would need to be done to get the engine into bare block form, can now be done without going that far. This means you could do the work with the engine still in the vehicle if you really wanted to. Remove the heads, pull the pan, take out the piston/rod assemblies, grind your new rings to fit, check your rod clearances, and install the new piston & rod assemblies.

This saves you from having to pull the crank and re-balance, as well as from having to hone the cylinders for piston to wall clearance.
