- JBA #1 Review by Jon
- Have a pro comp 3 inch coil lift and I was able to get my alignment to factory spec. I definitely love the high quality UCAs. The best on the market! (Posted on 6/22/2018)
- Very Satisfied Review by Jose
- My first lifted truck, did a lot of researching. Very Affordable. I get a lot of comments on how they like the replaceable ball joint. Plus the zerk fittings, allowing to grease easily. Alignment was "On the Money!" as was quoted by the alignment man. Again Very Happy (Posted on 5/24/2018)
- Amazing Product Review by Rick
- Bought these to replace my Camburg Ball Joint UCA's that blew a ball joint and boot after a year with no wheeling. I will never look back now, and I got my alignment today Caster was 3.7 Camber was 0 and Toe was 0. BUY THESE AND YOU WILL LOVE THEM. Other plus is you can change the ball joints on these without taking the arms off right in the driveway. (Posted on 8/15/2017)

- Good solid product Review by Ryan
- I installed the jba uca's on my 2014 tacoma with a 3" lift and was able to get my alignment back into spec. I looked for a long time after lifting my truck for a nice set of ucas and came across these on a tacomaworld thread. Marlin was great at answering all my questions. Awesome customer service and excellent product. I would definitely recommend them to anyone. Thanks again Ryan (Posted on 1/16/2017)
- GREAT BUILD QUALITY Review by PETER CASTANON

- Very Pleased! Review by Harold
I purchased the "standard" UCA for my 2015 4Runner in the early part of '16. I have had them for several months, I have wheeled a few times, and I have had no issues. The alignment came in great at about 3.5 deg caster. I love that they have the articulation of a uniball, without the maintenance. I think that the price is fair, and they are Made in the USA! Need a new balljoint? You can buy one anywhere, it's from a half ton GM truck. Just a few of those on the road!

- great upper control arms Review by ryan
- I love the use of these moog ball joints, it makes for easy replacement/service down the road. High quality craftsmanship in these solid UCA's is noticed right away. The bushing are high quality as well, and something many other brands skip over, but not JBA... these have the same bushings Toyota puts in their factory UCA's which means no more squeaky UCA's!!!
