The parts are top quality. Nice crosshatch on the iron sleeve, mic'd the bore, it's round and in spec, piston and rings checked out as well. I've bought a few of these Niche kits and the quality is hilarious for the price. I don't understand how economy of scale can be this advanced.

Excellent Service!

Parts were received in great condition and in a timely manner. I am very pleased with the service. Thank you for your business. Great job!
