    I just got my alignment today.

    When I did my lift yesterday, I set my LR bj at neutral "D" setting for a total of +2* caster. I also rolled my LCA cams around to max, pushing the lower bj all the way forward.

    So today, I had 3.8* caster to start. We changed the LR bj to a -1 "E" setting. The tech then pulled the LCAs back a little, to give me 2* of caster. I now have 3" of clearance behind my 265/65-17s on stock wheels. I gained an extra inch!

    This will help when I put 285/70-17s on with 1" Bora spacers.

    I understand that SPC recommends the 0 "neutral" setting for a 3 inch lift, but has anyone started with the +1 setting for the caster? I'm wanting to run 285s and wanting to see what others have done with LR uca.

    285's and neutral setting here. That's the standard for most with LR's.

    A +1 setting would increase caster and reduce rear clearance. A neutral setting is the recommended starting point, and some like me, have opted to go with a -1 setting for increased clearance & a little less caster. I got 2* of caster with my -1 setting and gained an extra inch of rear clearance. This was in prep for running 285s.

    Just to clarify, by -1 you mean -1 from the neutral position, so you are adding +1* of caster at the UCA correct? Because the neutral setting adds 2* of caster. Its funny, bbtacosurfer and I were just discussing this the other day, i want to switch up my caster to help with clearance at the back of the wheel well, but i dont really see anyone running their light racing UCAs at +1*. So you have 285s now and have plenty of clearance? What are your wheel stats or what are you running for wheels?

    Edit: read your previous post, looks like the 285s with spacers haven't gone on yet. Im curious to know how it works out.

    I have about 1/8" clearance to the cab mount, already chopped, locked and stuffed. I still rub the bottom of the fender flares and i don't want to cut much more off. So i am tossing around the idea of trying to move the wheels forward by changing the setting on the UCAs

    X2. Same here. About two years for me. Only rub when at full lock and stuffed....

    You are correct. A -1 ball joint setting gives the uca an overall +1* caster.

    Thank you UncleART for the clarification! I may try the -1 route to clear some room for 285s. Like Evan said, not a whole lot of folks running their LR UCA at this setting so it's making me wonder if it's the best route.

    I just measured again, and I have about 4" to the cab mount!!! (Stock tires & sport wheels). About 3" to the plastic well lip.

    I'm not sure what my factory caster was. But I think that it was a little more than 2*. My truck is stable driving straight but I feel the bumps in the road affect the steering more now than before.

    I ended up doing the same thing as bjmoose. I got the strategy from him. Re-read his post and you can get some good info. He did a great write up.

    Looks like they changed the install sheet again
    http://www.spcalignment.net/instructions/25470-INS_WEB.pdf
    This one shows only using 2 washers per side. When i installed mine i used two large washers on the outsides and 2 smaller washers on the inside per side. Anyone have any idea why they changed it again? Anyone only use 2 washers per side? :notsure:

    A bunch a cool stickers, a bada ass MetalMiller Tx Longhorns grill emblem painted Hemi Orange, JBA long tube headers with o2 sims, Diff breather mod, Red LED interior lights, Fancy head unit that plays ipod n movies, Also DIY install factory stuff like, factory cruise control, factory intermittent wipers, OME nitro struts with 886x springs and toy tec top plate, JBA high caster UCA's for better alignmnet and dey beefier too, Old Man Emu Dakar leaf springs in da rear with the gear, U bolt flipper, Ivan Stewart TRD rims with 33" K Bro 2's, some bad ass weather tech floor liners so I don't muck up my interior, an ATO shackle flipper for mo travel in da rear wit the gear, also super shiny Fox 2.0 shocks back there too, all sorts of steal armor for bouncing off of the rocks like demello sliders, AP front skid, trans skid, n transfer skid, demello gas tank skid, and a tough as nails ARB bumper with warn 8k winch, I'm sure there's more

    Just did an install on another members truck and was surprised that the instructions showed only using 2 per side as well. Instead I put 3 per side, 2 per on the forward bushings, and one of the stock washers on the rear bushing until I can pick up some fender washers to place on the rear bushings. I feel that not having washers on either side of the bushings will create a wash out on the grease, and after talking with SPC, they claimed they removed the washers because of a binding effect. Personally I don't see how it could create binding, mine came with 8 washers, and I have zero binding problems.
