Duramax is king of the mountain again

If true about the HPFP, that's potentially an outstanding change by GM. That CP4 issue really loomed large when I was looking at the various diesels last year. If they also fixed the DEF tank, the only remaining thing I don't really like on the GM is the IFS and truthfully that's probably not a very big deal - I just kinda like having solid tubes on both ends of the truck.

The IFS and the front end styling of my 09 duramax is about all I don't like about it. I always had straight axles and was concerned about the durability of my IFS until I nailed a lone parking curb I didn't see, hit it pretty hard/fast and fully expected to have broken something but it was fine. Still like the stance of the stock straight axle trucks a lot better though.

Just key the torsion bars up a bit, will fix the low ride ht. Plus, if your truck appears low compar d to some, the bars may not be indexed right. See a lot of variation in ride ht of the same model GM ifs trucks.
Agree they're tough as nails except the tie rods. Those need sleeved at least on the older Dmax trucks if putting a lot of power through the front axle.
I've beat the tar out of several ifs GM trucks and can't say they're any less durable than a solid axle rig.
