Question about the $1200 Jasper reman I dropped in a 6.0 last fall

Did that Jasper rebuild save my shop hours or just burn my customer with a ticking time bomb because that thing already has a weird knock at 15k miles and I'm starting to wonder if those cheap in-frame kits from the parts house would have been smarter.

Man I put a Jasper in a 6.0 last year and it's been running fine so far...

Jasper's always been a mixed bag with these 6.0s... seen a lot of guys get good ones but also a lot of those knocks pop up right after the warranty runs out. Usually that weird sound at 15k is a wrist pin or a bad lifter bleeding down, not just the injector rattle they all get. That in-frame kit from the parts house might have been more work but at least you'd know exactly what went in there and could match the parts yourself. Jasper has a way of sourcing their components from wherever's cheapest that week, and sometimes you get a crank that's a few thou out of spec.
