I just bought a set of chrome H2 wheels and tires and was wondering exactly what modifications are neede to intall these with no rubbing issues on my '04 duramax. I have already leveled the truck with some GM leveling keys, they raised the front end 1 3/4". I have stock whels w/ 265/75/16 now. I've heard about having to trim the lower front bumper plastic, tie back the inner fender on the driver side, and possibly space the front bumper out a 1/2". are these all thats needed? any help from you guys that have ran H2's would be greatlyu appreciated!! thanks!

All I did on my GMC was crank the bars about 5 turns.

How's the ride hoot?

I cranked the torsion bars, I moved the bumper out 1 1/2", I trimmed the bumper air dam, and the inside drivers wheel well. I also cable tied the emergency brake cable against the frame, so that when I turned left, the tire would clear it.

thanks for the info hoot, and thanks for the info and all the pics andrewfessler. It's nice to see the before and after pics. How's the ride after the swap? what about power loss? thanks again-:)

Power Loss?? What is that?

I really dont notice any, probably wouldnt either with my Juice. I run it in level3 and its plenty powerful. I have not reset my Speedo, so it runs around 7-8 MPH off. I use my gps for checking speed.

The ride, seems to be fine to me, my wife thinks it rides smoother. I have not gotten around to replacing my factory shocks with Bilsteins, probably do that in a few months.

I no longer own the truck but the ride was very good.

dmaxpower1,

You pretty much have it all down. You may still need to adjust the torsions up a bit, and don't forget an alignment afterward.


Heres the thread for moving the bumper on an '03 Chevy.

When I installed my H2's, my predator was "lost in florida". I did feel a power loss. After a couple of intersections my foot adjusted and it has not returned.
