I installed a new starter on my 1995 Dodge Ram Cummins, and it has exceeded my expectations. Ive had it for about 20k miles now. Installation was straightforward, and the starter fit perfectly without any modifications. From the first turn of the key, it cranked the engine smoothly and reliably at a great price. Since installing it, my truck starts every time, even in cold mornings, which has been a huge relief. The starter feels durable and well-built, giving me confidence that it will last for years of regular use. It’s clear that this is a quality part designed for heavy-duty performance, just what you need on a classic Cummins diesel. Overall, I’m extremely satisfied with this starter. If you’re looking for a reliable, strong, and easy-to-install replacement for your Dodge Ram Cummins, this one is an excellent choice.

Good quality except for the supplied bolts.

So far starter works great. Be careful if you use the supplied bolts. They are not good quality. The last thing you want to do is snap them off in the block. The starter itself really spins the engine over. If it lives long, it's a great deal for the money.
