    Synergy UCA - Rear pinion angle

    Recently installed a 1350 u joint rear DS and have been running stock rear arms with 4” EVO Plush Rides. With the new drive shaft I needed to rotate my rear axle up to match pinion and DS angle.
    I just installed some Synergy rear UCA’s and now it looks like I need less pinion angle. Catch is that I believe the arms are adjusted all the way in.

    Does anyone have experience with these arms? Are they too long to use with stock lowers or is something wonky with my setup?

    Pic is of the DS v pinion angle with the new arms. About 2* too high on pinion

    Assuming you have the uppers set as short as they’ll go, consider getting either adjustable lower arms or synergy fixed arms, which are 1/2” longer than stock, cheaper than the adjustables, and should correct your issue. I have the adjustable uppers, fixed lowers, and 4.5” springs. All synergy. Can set the pinion properly with that set up.

    Shorter uppers or longer lowers are the only way to fix your angle.

    Sorry.

    Also, that driveshaft looks a bit short to my eye.

    I sure hope it isn’t. Ordered it from Adams with dimensions and lift specs.

    Put it on stands, take the wheels off, and let the axle fully droop. If the shaft separates, you’ll know it’s too short.

    Sounds like a next weekend project AFTER I install the new arms I didn’t plan on buying 🤣

    Not sure about the synergy arms but I'm running Currie uppers with stock lowers and it works out with my Adams DS but I am 1.5-2" lower than your lift so it's possible the height is just too much to have only adjustable uppers.
    Side note when I ordered my Adams they mentioned how much blue should be showing (can't remember off the top of my head) but mine only have maybe 1" of blue showing at ride height. Might be worth giving them a call and asking about that. Assuming you are at ride height in that picture I agree it looks a bit short

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
