    Default ARB Bumper Time!!

    Well, surfing craiglist for an ARB finally paid off!! I found a never-installed bumper sitting in some dude's garage for less than 1/2 what a new one would cost me! I was pretty excited to bolt it on, and I was working in poor light after dark, so I didn't get any pics of the initial install. I did snap one yesterday at work:



    Though I'm happy with the function of the bumper, I think ARB could have done a better job with it. First, it is HUGE. Like almost too big for the truck. If I bolt it on using the intended mounting holes, it sits WAY high on the front of my 2500HD GMC, and the grille doesn't fit. I think the Chevys might have higher hood lines, and hence higher headlights, grille, etc, but it looked dumb on my GMC mounted that high. And the grille didn't fit because there's a black filler piece between the grill and factory bumper that would have needed to be removed. I lowered it about 1.5" and it is looking much better, though still a little high. The bumper now sticks into the wheel well a bit too at the top, so I'll likely do a little trim and re-weld on that and get it looking proper.

    Unfortunately, one of my co-workers is borrowing my truck to move, so I won't be tackling any mods this weekend, but it's getting the 8274 that I have laying around as soon as I get it back. Little plasma cutter work to be done, but the structure should be plenty strong for the 8274.

    I'll post pics as the mods get done.

    Those new generation H2 wheels look much better than the earlier design!

    If you are looking at Bilstein, check out shockwarehouse.com, they have a discount code on most truck forums. I picked up a set of Bilstein HD's for my 06 1/2 ton Silverado.

    Google "shockwarehouse discount code"

    Good job. You made it longer.*
    But seriously, that looks good on there. Any idea how heavy that ends up being, with the winch?

    *in reference of course to the ol' 96er

    Longer and Stronger! (Viagra commercial? ) The longer thing is really obvious from the side, but really only about 6" longer, and the approach angle actually improves, even with the bumper lowered! I'm going to try to trim it a little and slide it back some more too, which should help things a bit. My truck is a CCSB, so break-over is always the limit anyway.

    The bumper isn't as heavy as I thought it might be. I would guess 120-150lbs The brackets are really heavy. I think they could have lightened them up a bit and not suffered any loss of strength. After I add 120lbs of 8274 I'll have bumped the nose weight of my truck by about 250 lbs. I'm OK with that. It'll offset the 1500lbs of Hallmark camper and motorcycle on the back.

    I just realized that I put shocks on the truck and didn't say a peep about it. I ended up going with Gabriel Ultras. I wanted some low budget shocks with medium damping. Rancho's and most of the big offroad shocks tend to be stiff, Bilsteins are too expensive for my taste, and sometimes aren't valved well for washboarded roads. Gabriel had a big rebate, and all the reviews I found said they were the ticket. I'd have to agree. The fronts are just ever so slightly firmer in compression I think and they actually have rebound damping, which the factory shocks were lacking. The rears are noticably firmer on compression, and again they have rebound damping! I don't know who tuned the factory shocks, but there was not much rebound compared to the level of compression damping. Made the truck want to pogo over every bump. Gabriel Ultras are a good value and ride decently without being too soft or too stiff. No more tail bounce with the camper in, and the front doesn't hop after a dip like it used to.

    Well, I finally got around to mounting my 8274 in the ARB this evening. It went pretty smooth considering the bumper wasn't designed to fit it.

    Here's the bumper, plucked off the truck with the help of my engine hoist. (I work alone...)



    And the back side, with white paint pen showing the section that I'm about to remove. I checked out an ARB on an early Land Cruiser a few weeks ago. (The only ARB that I know of that's made for the 8274!) It didn't look like it had any extra structure than my bumper will have after I remove the top plate, so I'm not worried.




    Here I did some cutting and knocked out a big chunk. I think there's still plenty of structure here. More than enough for my use anyway. I'm planning to use a piece of angle that came with the bumper to bridge the gap once the winch is in place. That should put some stiffness back in the outer wings of the bumper.



    Cleaned up the rough edges from the plasma and test fit the winch. I actually had to trim another 4" or so off the pass side to make room for the brake. Once I had it fitting, I primed and painted the edges satin black Rustoleum. It's a good match!



    Test fitting the winch to make sure I cut enough out. (The 2nd time...)



    And here it is assembled and ready to go back on the truck!! It still needs some plate work on the top to close out the big holes that were for a lay-down winch, but at least it's functional now!


    I got it bolted back on the truck, but it's midnight, so I didn't get it wired. I'll get a few pictures of it mounted on the truck tomorrow in the daylight.
    My ARB now looks much happier holding a winch. Just need to figure out where to put the license plate now...

    [I doubt the heat shield is really necessary, as there's lots of clearance to the exhaust on my truck, but I put it on anyway. The truck really does ride better empty with about 10-15psi in the bags. Picks up the rear about 1.5" too, which gets it off the overloads, and makes it look a little better IMO.
    Now I'm realizing how soft my 150k mile OEM shocks are... Time to save up some more $$...

    My bad. I keep thinking that I'll take pictures somewhere cool, but I just came back from Moab with no pictures of the front of the truck, so you get driveway pics.
    Winch sits pretty low in the ARB actually. The whole combo might be blocking a little air from the radiator, but I can't really say it's the fault of the 8274.




    Switched to the skinny tires for winter too. Wheels are plastidipped white. I'll just powdercoat them when the plastidip starts looking rough... It took a lot to coat them, and white is expensive.


    Now it looks like it needs biggier tires... I'm going to continue to hope that Cooper brings out a 255/80R17 STMaxx for me.
