I'm now hearing second-hand that the Grenadier project is on the "backburner" at 74Weld. They haven't been replying to my inquiries via email or phone, so I'm about ready to drop it. I may have to talk to Jay Couch again about his portals but I would really rather swap the axles. I'm pretty sure I'll be putting his front bumper on.
I have figured out my plan for the suspension working with Ben at Filthy Motorsports in Boulder.
I'm very close to my bump stops and really need to get some springs on. The Silenus roof conversion will net +285 lbs and the truck is pretty fat already at 7620 lbs with full tanks and my typical load; 3520 lbs front axle, 4100 rear. I'm aiming for a 1.5-2" lift over OEM when settled under weight. In order to get there we'll try the 2.5" lift Eibach springs (E30-34-001-06-20) in front as the only HD front springs are probably too much. In the rear hopefully the HD 2.5" (E30-34-001-06-02), aka "500 lbs", springs will do the trick. In reading others' experiences it seems like the 1000 lbs springs may be a bit much, but I'll switch to those if the 500s don't cut it.
I looked at doing something interesting like cutting the upper shock mounts out to try and get more travel, but it would require some significant redesign to get any meaningful travel without just extending the bump stops far down. The rear shock body mount isn't far below the rear cargo floor and I don't want to protrude into that. In front the steering shaft and air box aren't far above the mounts. The OEM shocks get something like 8-9" of travel. Ben is working up some custom King 2.5 9" shocks, which will be good enough if tuned well and he's one of the best in the world at it. I also ordered the Agile Offroad remote res relocation bracket for rear left since I have the aux fuel tank.
I'm also considering getting the beefier Eibach anti-sway bar and adding some disconnects. SDI makes universal electric disconnects they call
ELink that are looking very attractive. Knowing myself, if I install the Metal Cloak disconnects I'll be too lazy to use them as much as I would if they were just on an electric switch. The front sway bar links are quite short so I need to see if clearances will allow a link that's a bit longer to allow some compression travel when disconnected. The rear links shouldn't be an issue.
