Rpms

[AlexFolino]

First post here (love the site!) and i recently bought a M1008. I know this truck has 4:56 in the rear. This truck will see highway driving about 20-30miles round trip everyday. Do i need to worry about anything considering it is a diesel and the rpms are going to be high around 55mph. Generally i dont go faster than 60 ever just i worry about this setup and will it cause a problem down the road? I want to put taller tires on it to help out but cant afford them for another few months and with the snow coming i need to run this truck now... ALl help is appreciated.


thanks!

55 will be fine and even 60. These 6.2s motors dont like high rpms but at 55 you will be just fine.

If i went to 35" tires would this help out in terms of lowering the engine RPMS?

You can use that to run the numbers.
