Callies Performance Products are very well known for their crankshafts. They started producing high performance crankshafts in 1989. Since then, they have expanded their catalog and have continue to be America’s #1 racing engine components manufacturer.

We talked to Callies Performance Products last year at the Performance Racing Industry Show and they told us they were focusing on the Gen III Hemi and there would be multiple new products coming in 2023. We are not even through January and they have already released some great new parts.

The newest additions to the Callies’ catalog are new Gen III Hemi Main Caps, Main Studs (#10414) and Head Studs (#10625). The Main Caps come in three different options, Main Caps only (#000-G3HKIT), Main Caps/Main Studs Combo (#000-G3HMSTK), and then a Main Caps/Main Studs/Head Studs Combo (#000-G3HMHSTK).

These new Main Caps are machined from billet 4140 and work with OEM blocks. They have left ID stock on the caps for proper boring and honing. Pair these new Main Caps with one of Callies’ crankshafts and Compstar connecting rods and you have a bottom end that will handle a ton of power. We can not wait to see what new parts will be next from Callies Performance Products.
