My 1996 Dodge 3500 has been running strong since I bought it and with 270,000 miles, that's saying a lot about for my stock engine. So far, the only thing I've really had to do was replace the stock intake filter with one from K&N. I've also upgraded the manifold with a Banks twin ram intake manifold and to keep everything moving smoothly I installed a BD steering stabilizer. I've had this truck for a while and it's helped me do everything from hauling to grocery shopping.
