    Colorado ZR2 parts in an H3

    Was abit bored and came across this video of someone installing ZR2 parts on a Hummer H3. So far the rear shocks off the ZR2 and the front half shafts can be swapped on the H3 (very pricey though)

    Interesting. I wonder if the half shafts pivot at the same place though, meaning if the ZR2 shaft is pivoting further outboard or inboard than where the facotyr h3 halfshaft is, wouldn't that affect performance somehow? suspension geometry. I have no idea if this is the case and they look close in the video but wouldn't that still be an issue in the long run?

    We have the CAD files for both trucks it's hilarious how close they are on certain parts. We did a comparison on Instagram/ FB measuring and they both have exact same wheel travel.
    Current:

    2006 Red H3 Adventure/ luxury- 37" iroks, HD tierods, steering rack kit, custom front IFS HP Dana 44 diff with Yukon zip locker, Np241 manual T-case, 6.0L VVT/ 6L90 swap

    2008 Black H3 Alpha- HD tierods, steering rack kit, Custom HD lower control arm bushing kit

    2007 Black H3 Luxury- 1.25" bodylift, elocker, 4:1 t-case, steering rack kit, custom front IFS HP Dana 50 diff with truetrac, 37" bfg km2, H3x 18" wheels

    2009 Black H3T base- custom front IFS HP Dana 44 diff with truetrac, 37" centennial trail hogs, H3x 18" wheels

    2008 White H3 Adventure

    I think we might have too many of these things now...

    Too bad the ZR2 takes soo much more effort to fit 35s.

    Yes fender openings are tiny for some reason. You can fit them with the GM performance bodylift though

    Pretty sure you just answered your own question. Why give customers access to free upgrades when you can force them to buy additional products from you? Not saying I agree, just how products are made these days.

    The guy in the video above did instal a BDS lift to instal 35s but he still needed to trim and it looked tight (compared to the H3)
    Interesting thing is I stumbled on a ZR2 related thread on coloradofans and most of the members on that thread were previous owners of H3/H3t with the adv package

    I have a BDS lift sitting in the garage for my ZR2 right now. Plan on buy the larger AEV fender flares and cutting the fenders when they are released. The AEV fender flares and trimming are supposed to clear 35's with just a 1.5" level kit.

    I would have to disagree with this. The H3 only has 5 or 6 inches of front wheel travel and the ZR2 has 8.5 inches by factory specs.

    Is that shock travel. I thought the zr2 was supposed to have 10 of front wheel travel.

    No, I am talking wheel travel. The ZR2 has 8.5 inches in the front and 10.5 in the back, roughly.

    Thanks for the info. Those shocks must be really impressive based on the performance Ive heard about the front with that limited amount of travel.
