Rotating Assembly
Our Price: $2,600.00

TMeyer has committed to having Molnar Technologies produce the crankshaft and connecting rods for our new assemblies. The Track Boss rotating assembly is setting a new standard with its exclusive “Centralign Design.”

All competitor assemblies that use the small block Chevy connecting rods have a problem aligning to the center of the piston. The Track Boss rotating assembly with the Centralign Design is engineered to correct this misalignment. True center alignment means better ring sealing and less twisting of the piston.
A Chevy rod will connect the piston to the crankshaft and produce power, however, you may leave power on the table due to the loss of ring seal. Late Model dirt racers have reported up to 30HP gains by using connecting rods with proper alignment.

Bottom Line: Get maximum power from your engine with the correct parts!

Get the Track Boss rotating assembly that has the Centralign Design.

And, when you consider all the parts included in the kits, the price is tough to beat!
