@RangerStranger here you go! I had my alignment redone and asked to get the camber to as close to 0.0 as possible. I have a 2” ford ranger lift spacer and stock uca.

They said to get the camber any lower I would need an aftermarket UCA. Have you had your alignment redone yet?

Also it’s worth noting that the tech did not want to get the caster numbers lower than the 0.7 but i made them do it twice. They said that the lower the number the more tire wear I would have.

I talked to a couple of the big guys in Ranger aftermarket parts and found out a lot of useful information. (SVT, Bajakits, Camburg and APG) Here’s where the problem comes into play. All of the aftermarket arms were designed to accommodate the stock Ford Ranger or with aftermarket suspension such as Fox, King, Icon, etc. Since our Tremors come factory with Fox 2.0 Suspension and retuned leaf springs were already sitting at 2-2.5 inches of lift, so we’re already within the specs of what the arms were designed for. Meanwhile we’re over here installing 1” and 2” leveling kits the get more lift and level on the front of the truck. These companies that made the aftermarket arms make them bigger and stronger for practicality and abuse. While normally this is a good thing, it’s really bad for us because we’re now sitting between 4-4.5” of lift and completely messing with the geometry. The major problem for me is that the BajaKits UCA is a fixed upper control arm. Meaning there is no adjustment factor at the pivot point and you can’t tweak it for alignment purposes. Typically this is where an ADJUSTABLE control arm would come into play but after talking with different companies (I’m not talking about the receptionist, I spoke with lead techs, designers and the actual owner of APG) I was literally told that they would love to sell me an adjustable arm but even with that adjustable arm being sucked all the way in up top, they would still be just as big as stock arms. Now while our stock arms can technically handle this 2” level it puts a lot of stress on them and maxes them out when we go to do an alignment. Basically we’re playing in unmarked territory with our geometry and our trucks were never meant to have this much lift. With all of that being said im throwing my stock arms back on and selling the bajakits UCAs. I’m planning on purchasing the APG midrunner kit later next week to get everything dialed in the way it was designed to be.

I don’t understand what the issue with the tech was but you definitely do not want positive camber, it wears the outside of your tires and worsens your handling. Preferably you like to sit between -(0.1) to (0) degrees. Also toe is a major factor as well and should never be toe out, it makes driving on the freeway more squirrelly, imagine pushing a tow car forward with the wheels facing out. Typically you want (0.01) of tow in. I attached an alignment sheet to show you what I mean.

I do not think that the oem uca is adjustable either. Unless I am looking at it incorrectly, it attaches the same way to the truck as BAJA and other aftermarket UCA’s.

I was under the assumption all the adjustment comes from the lca

At the 0:50 mark Icon talks about how the lca is a typical adjustment point and their uca is fixed. Now it appears to be fixed at a different angle to provide more castor.

The video from Baja looks the same. They build in more caster into the UCA but it is a fixed design.

The stock upper control arm isn’t adjustable but it’s shorter than aftermarket control arms which gives better geometry for alignment. Here’s what the svc adjustable arm looks like. You can move the pivot joints inward or outward to adjust alignment. However I was told even when they’re adjusted all the way in they’re still as large as stock arms.

Correct but with running a lift on top of a factory lift these arms aren’t compatible.

I suppose at the end of the day this is where I disagree.

Icon sells 3.5” lift kits and aftermarket UCA’s to work with those lifts. A 2” spacer lift on a tremor would put the static height at roughly 3.5” for a non-tremor model. Now suspension articulation and droop is a totally different topic here with a spacer lift vs new coilovers but the alignment process should not change because they are both done at a static ride height.

Maybe the one thing we can agree on is the Baja UCA so far is not work for your application. Although, I would think the easiest solution is taking it to a different shop for an alignment.

I wheel mine as well. Spacer lifts don’t help with anything off-roading except maybe to fit bigger tires, which aren’t needed to fit 285s.
Hi Greg , do you have 285/70-17 on your truck? Stock rims? Would you mind sharing what you did for them to fit?

I have different wheels but they resulted in essentially the exact same backspacing (less offset but wider rims). I needed to swap out the intrusion beams for ReadyLift beams.

We’ve already gone down this road. I’ve take it to 2 different shops, one off road shop with an alignment machine there and another shop that does laser alignments. My lower control arm is maxed out. There is no other way to get less camber than to pull it out more. The geometry doesn’t work because we’re stacking lifts on top of lifts. We just talked about all of this man. Plus to the multiple companies that make all of the aftermarket parts and UCAs! You can disagree with whatever you want to but you’re wrong. And yea, icon does make a 3.5” lift but they make a UCA SPECIFICALLY for that lift that’s different than the rest of their ucas. We’re just going in circles now with this topic.
Fact is, you can NOT run a 2” leveling lift with aftermarket control arms on a Tremor because they weren’t designed for that.
