    I'm currently going down the rabbit hole and trying to figure out how to maximize usable travel in a mid travel/stock length IFS setup. This would apply to anyone trying to do the same thing, but for context's sake I'll outline what I'm thinking for my truck.
    It's currently on 37s, Toytec 2.0 coilovers at 1.5" of lift, with the necessary trimming/tubbing done to fit the 37s. Nothing else has been done to the front end. My plan is to dive into the front end in June after bear season is over and I can have the truck out of commission for a while. I don't have access to CNC plasma, tube bender, or a press brake, but I can design/cut/weld etc with the basic stuff I have. Using Hubs or Send Cut Send is an option if needed.
    This will include:
    JD Fab .25" shift UCA
    Gusseted spindles, double sheer steering
    New stock LCA
    -Reinforced connection to bushing sleeve, including cutting them off and moving ~1/2" forward
    -Reinforced bump pad for air bump, all the way to the bushing sleeve
    -Skid plates
    Likely a modified Tundra or LC200 steering rack, with heim steering
    Reinforced, possibly shifting LCA mounts forward. I'm going to be cheap and not buy the JD fab LPK like I should.
    Cut off current bump stop mount entirely.

    While considering where to mount the air bumps to maximize up travel, I'm trying to figure out how far to push it. Potential limits of up travel and solutions include:
    -Unusual stress on LCA bolts?
    -Tire hitting fender and fender well-have to cut it out and potentially make new fender wells
    -UCA hitting fender well-same solution as above
    -CV or steering hitting something? I can't see that being an issue so far. They'll be at far less of an angle than at max droop
    -Tire hitting frame-Notch frame to fit
    -Bump stops-adding air bumps

    The obvious next step is to remove a coilover and cycle everything up to the current max. My hope is to gain as much as 2" more up travel. Moving the stock bump stop and some sheet metal are a guarantee. Has anyone else given this a shot, and what issues did you end up finding?

    That's one thing that I forgot to include initially. I'll likely need to move the coilover mount up, and utilize a longer travel coilover to prevent that from being my limit.
    I'll have to keep an eye on ball/uniball geometry when I cycle with the coilover removed.

    I think you will be maxing out balljoints/uniballs pretty quick with anything other than the stock travel range. My Spcs with the Uca bottomed out touching the stock fenderwell is damn near maxing out the joint (80 degrees of range)
