I run 4.88s on a truck that originally came with 3.91. Love the extra gearing for trail riding and surpassingly there has been no MPG drop because of it. The thing just feels reved out at times but I have no problem with that. I was driving the other day and I got thinking what kind of long term affects this has on the engine compared to a stock setup.
Naturally I’d say high rpm situations create more wear but that’s also because I think most of us naturally think of racing/wide open throttle/ high load applications when it comes to high rpm. What about guys like me who are revving high because of different gear ratios but in all reality are driving around with a low load on the engine?
If you do the math you’re essentially doing an extra 25% RPM. So instead of cruising at 2200rpm you’re doing 2900rpm. And I know this isn’t exactly “high” in the world of engines but it is higher and I’m curious nonetheless
Is that extra 600rpm getting you better splash lubrication on the cylinders?
Do your piston rings stay cleaner due to more oil flow through the ring packs?
Do valves run cleaner because of it?
Or is it all just extra wear and tear?
i do want to say that I’m not worried about it as being an issue or anything as much as it’s a curiosity and wanted to see what other people thought.
