Anybody came across drawings/sizing of those shims on the internet ? I searched but can't find anything. Of course I can fabricate them after the original ones once removed, but I'd rather prepare them in advance, if possible. Hate machining parts during the installation. Helper gets paid for...

Is there room enough for a 1/4 shim in the stock location ? And is the bolt long enough ?

According to this chart, a 3" lift would require 1/4" longer LCAs to restore stock caster. Now the question is if a 1/4" additional shim will fit. Buying new LCA's just for 1/4" adjustment seems a waste of money to me. Re: Pinion angle I wonder why one should be concerned about front pinion...

Well I still believe that measuring stock geometry and feeding the numbers into a simple smartphone app such as "triangle calculator" is the easiest and more precise way to do it and all you need is a tape measure. Before the lift: 1. Measure distance of LCA front eye (bolt axis) from ground...

If you mean placing the angle finder on top of the spindle (video linked below) that is a rather approximate method. Infact in the video the guy is puzzled by the fact that the two spindles are at different angles, which of course is not possible, unless they were welded at different angles on...

Tubular adjustable lower control arms for 0 to 4" lift, with poly bushings, are 100 bucks shipped. The shims of course don't cost nothing but replacing the 30+ years old LCA's would be a good idea in any case. There's even a bundle UCA + trackbar at 120, not bad considering the trackbar alone...

Well the other day I bought three pieces of 4" long neoprene rubber bar to turn some bushings for the ATV. 3/4", 1" and 1.5" diameter. Total including taxes is about $30. Everything has become so expensive after Covid. Argon bottle refill is $80, was 50 before Covid... Believe me when I say that...

Yes, gear speed calculators do not take into account the mass (and related inertia) of larger wheels, as well as worse CX due to the taller stance. They are perfectly fine to understand how much the motor RPM will vary at a certain speed, but how fast the truck/motor will reach that speed/rpm is...

Re: Caster angle That's something I am determined to address. On this suspension design poor caster angle not only results in twitchy steering but it is the primary cause of death wobble, which is something I'm not taking a chance on. Calculating how much the lower control arm would have to be...

@ Evans03 I guess 03 is your date of birth ? Anyway, looks are personal and with your answers you are not adding anything to the discussion under a technical point of view. Not to mention your suggestion to run 35's with a 3" lift, a 2.1 liter diesel motor, Dana 30/44 and go wheeling with it...

Evan03, 30's on stock suspension require removing the fender flares and 35's on 3" lift will fit only with MAJOR fender trimming and will still look stuffed real bad IMHO. As I said I don't care off road capabilities, as this truck will never see any off road use. The purpose of the lift is...

@ TimMn, I dont prefer add-a-leaf for vehicles that won't see much off road use because they almost always result in a harsher ride. Sag generally happens because of (torque related) spring wrap, and tall lift blocks don't help in that regard due to the increased leverage. Due to the weak...

XJ enthusiast from Italy - where lift kits are hard to find and very expensive... Im planning a budget 3" lift + 30's for my '88 XJ (with the weak 2.1 liters Turbo Diesel). I have previous experience in fabricating lifts, as well as lathe, mill, MIG and TIG welders, but no specific experience on...
