Default Confused on what panhard bar to get

Hey fellas I need a panhard bar. I know I want an on car adjustable one, but what is the difference between just the on car adjustable and the double adjustable? What is the advantage of going with the roto joint vs just the poly bushings? I'm only going with UMI... Thanks.

On car adjustable is just that--adjustable in place installed on the car. A Double adjustable has adjustments at both ends and you have to loosen and tighten the jam-nuts at the ends to change it. The jam nut on the body side is pretty much impossible to get at when on the car--and on car adjustables are easier to deal with for that reason.

Poly vs. Roto-joint. Poly is inexpensvie, but doesn't flex very well, and over time is prone to mis-shaping. A roto-joint allows free articulation of the axle in all directions except the one you don't want (laterally). The Roto-joint type have less deflection when loaded than the poly bushings making the body/axle stay more inline (which is the job of a PHB).

This is the truth here. Get an on-car ajustable that has the adjuster in the middle. I have UMI double adjustable roto-joint PHB and it is a PAIN IN THE *** to tighten the locking nuts. Either take it off the car and tighten it while trying to keep both ends from twisting simultaneously, or invent your own tool to do it on the car.

If the vehicle is strictly street use and that is it the Roto-Joint will work fine however could be overkill for your application and the poly bushings would be best. If the vehicle is exposed to some track use such as autocross we recommend the Roto-Joint to allow suspension movement like Sam mentioned.

Below I posted links to our two most popular items, please take a look and I will be glad to help with any additional questions.

On-car adjustable panhard bar- polyurethane bushings

On-car adjustable panhard bar- Roto-Joint

Hope that helps!

Thanks Sam, Arc00TA, and Ryan! Ordered it this morning.

Sam, I can't wait to get some Koni's and your springs. You sold some to my friend recently, they look and perform amazing!

By the way, I love my roto joints on the street. I just don't love adjusting them.

How many miles can you get out of a roto joint before it needs rebuilt?
What really lasts the longest a poly bushing, rod end, or roto joint?

We are not sure exactly as we haven't worn a Roto-Joint out yet. If properly greased the delrin inside should last a long long time. The delrin is a high wear resistant material and so is the hard chrome plated 4140 spherical ball. It will take a lot to wear one out..

A polyurethane bushing will last a long time as well. If properly greased they could last a 100K miles I would say.

Rod ends are going to be the most high wearing item and they can wear out in 15-25K miles.

Hope that helps,
Ryan
