Good UCA recommendation

[BADCLOWN]

I’m starting to accumulate parts to lift my TRDP for when the stock tires give out. Some type of wheel on 34 inch tires, toytec 2-2.5 inch lift (spacer front, new spring rear system).

I’d like to install some aftermarket UCAs at the same time.

Looking for recommendations on a solid pair to use.

Solid UCAs… excellent customer service and follow up.

I like the Ironman Pro-forge. Look good, good amount of caster, and very low maintenance (don't have to grease the bushings every 3-5k miles).

there are so many good ones out there, so get what you like.

Depending on how you use the rig, you may also want to consider serviceability (ie greasing, uniballs vs ball joints, etc)

I don't know, mine weren't really awesome. Craptastic balljoints failed in a few thousand miles. They also had a nasty habit of breaking welds back when they were tube construction. Interesting that they have gone to a forging - it's massive overkill for the application and going to be much heavier than needed, but way better than broken welds.

After trashing my SPCs, I've done about 250k miles on TCs without issues, other than the obvious - squeaky poly bushings and constant uniball replacements. The cromo construction (4140, IIRC) of the TCs are also massive overkill for the application, but at least they aren't heavy, but they are expensive.

Outstanding customer service, built very well, lifetime warranty.

I don’t want to be regreasing stuff every few thousand miles. I’m looking for a “set it and forget it” set of UCAs that I can have installed and not have to think about.

I’m doing UCAs to avoid having my CV boots torn due to the lift. I had a 3 inch toytec lift on my old 3rd Gen with stock UCAs and ended up having torn boots

Aren’t Dobinson UCAs maintenance free? How do they hold up over the years and is the built in caster enough for a 3” lift?

Thanks

what? UCA's have nothing to do with your CV boots:tea:

So, UCAs will have little to do with that if any it will allow your alignment angles to be at or closer to specification . The biggest thing to help your c.v shafts with a lift will be a differential drop kit, this lessens the stress on your cv shafts and flex on the boots.

I have these and have tortured them as much as I can for 2 years. Love them and every shop I've had my 4runner in has said they are worth every penny.

Dirt King's UCAs are hard to beat. I'm sure they'll be going on sale soon. Buy the dust caps as well to protect the grease fittings and keep moisture out of the ball joint cup on the arms.

I chose Ironman ProForge UCAs for that reason.

They're not adjustable like the SPCs and others, they have built in camber and then the alignment shop just adjusts the LCA appropriately like normal.

They use an OEM spec ball joint, so it's just normal, no additional greasing or maintenance required.

As others have said, UCAs will not help with your CV axle angle. Really that comes down to your overall lift height. The higher the lift, the higher the CV angle, the more stress on the joints. A diff drop will help, but not much in my experience, and that moves the stressor slightly off the CV axle and onto the differential pinion since the diff is now lower.

I really hafta agree with the JBA UCA's, they are solidly built, awesomely responsive customer service. I pair with the Toytec lifts, it's the preferred setup I install. I also like the way the red looks up in there.

I have the JBA's in mine. I had SPC's in a Tacoma a few years back and never cared for the way the ball joint mounted in them. Only had them about a year and sold the truck. I probably have 40k on the JBA's and no issues. Hit them with a grease gun every oil change and they are good to go. If I ever wipe out a ball joint it's a regular GM part I could easily get local.

Which UCA’s offer the most positive caster adjustment?

Ah, well I thought UCAs helped with the suspension geometry and keeping the CVs more aligned. My bad.

Sounds like JBA or SPC are the top choices.

Has anyone installed the toytec diff drop? It says that the TRD skid plate may need bigger spacers. Anyone have experience if this is true or is the diff drop kit plug and play with no figment issues on the skid plate?
