Does anyone know the average lifespan / estimated opperating hours of a U-Joint in a CV shaft for a K5?

Well my CV combo seems to last about 2 years street driving and about 9 o's off roading. But I have some severe angles

I guess thats acceptable.. 8in lift.. yeah that would create some rough angles, especially on the front. Your truck looks really good (especially like the winch), I'm hoping to stuff those same tires under 4"susp/3"body lift .Thanks for the info!

You wouldn't happen to know your engine rpm at freeway speed with those gears without overdrive would ya?
