Pre e-log 1999 build date Cat 3406e engine. 550 HP, 18 spd. trans. 1.6 million total miles on truck. Approx. 300k on rod and main bearings. It had a new clutch and a reman transmission put in around the same time. Less than 15k miles on Caterpillar reman head and camshaft. New kingpins. I have the paperwork for the head, camshaft, and kingpins but not for the other work. Runs great!
