Longevity and replacing 5.29 gears on a new truck

I am home on wheels at the moment and looking to upgrade the drivability of my truck. I have an OME lift with 275’s. Weight of camper and wanting to go to 35’s I feel 5.29 gears is going to be very helpful. I have 44,000 miles on truck. Would regear help with overall lasting of truck drive train? I’m hoping to get 150,000 out of this rig. Living in CO with mountains and passes. Gears would be a great asset. It’s hard to offset the cost with mileage loss right now, but curious if it would help truck last longer. Anyone have any real world reviews of their regear?

thanks guys. Love this forum

When you add enough permanent weight, a re-gear will help preserve the durability of the drive train. Things will be working easier due to the lower gearing. I've heard of some people having trans issues running huge lifts and huge wheel/tire combos. I forget who it is, but his lift and wheel/tire combo ended up blasting the trans. Re-gear will also help you get back some of your lost mpg due to weight adders. Any sluggish acceleration will also be addressed.
