I made it to IIRC about 75,000-80,000 miles on the stock belt. If you are worried about the belt, do what billie here does and carry a replacement.

 

Just installed a new one at 84 k . It sure was a pain in the a$$ to replace.. Anyone know of an easy way to install one ?? I had to have a person on top of the engine & 1 on the bottom where the tensioner is located... Had to turn the belt side ways to get it on top of the tensioner

312k and change on the truck,,its the org belt installed when they put the exhaust brake on at dealer. couple lift pumps, u-joints, and front end pieces, except lower BJ are OEM yet and tight. Tranny went at 237k, 6th gear brg.

 

They are a pain but its surprising how motivated you are on the side of the road

I took mine off to inspect and tried my new one to make sure it fit. Twice is twice the PITA. At least I know if and when the time comes.

I keep a spare fuel filter too.

 

wow... amazing... what year is she?

 

04.5 DRW 2x4 edge w/attitude, str8 pipe, airaid a/f, rest is OEM. Rotella synthetic w/ Lucas, Mopar fluids in trans/rear. Pulled a 53' flatbed since new. Change oil and do analysis every 20k, fuel filter @ 5k running Lucas in fuel as well.

 

At 101,000 mine still looks like new.

Some day when I think of it I will pick up a spare buit it is not shoing any signs of cracking or wear yet.

 

I hate to know I had to replace this belt on the side of the rd... Might just have to call wrecker
