You are better off sleeving your USA made jugs. These are Chinese made and are a softer grade iron which will wear out faster when using chromoly piston rings. The bottom base flange is to thick and the fire ring (spigot) is taller than factory jugs..this could cause a problem if using .015 thick copper head gaskets. Get your originals bored or sleeved or shop around and find you another set. I've been building Ironheads for years and would not recommend these jugs !

Works just as it should. Got her back up and running great. Would have been nice to have instructions with it, but between the maintenance manual and the internet, was easy to get the ring gap, spacing, and assembly. Great product so far.

Made in Taiwan. That is seriously disappointing. Also poor quality machining. There is excess material around the cylinder base flange that has to be ground away to install the cylinders. NOT buying ANYTHING from V-Twin again!!!

The fit and quality seem ok for the jugs and Pistons but did not like the instructions for the rings and did not receive any for the direction of the Pistons them selves. Good thing I took pictures when taking apart. But biggest negative is that everything was made in Taiwan, for anyone putting parts on a 40 year old American motorcycle I believe it should just be usa built

Just what the old girl needed. casting is thicker than stock and a wrench needs to be ground down to put the base bolts back on the studs.
