J-Arm v A-Arm


Recommended Posts

Hey guys I had a quick question. I have a few banshees and one happens to be a 89 and is J-Arm obviously. The other two are used for ice racing during the winter and this 87 is kind of just a parts quad that is laying around. I do not do much during the summer other than work and there are near by flat tracks and was thinking of taking this third shee and turn it into a flat track clay quad but to be different thought of using j-arms. So my question is would this even be worth it or is this just a dumb idea. Please weigh in on this but please dont just say a arms, thats why they changed to them. I understand that using a-arms would be the more logical and probably the better route but wanted to try something different because I find it hard to believe that running j-arms could be that big of a difference and affect how well you can finish so thats why I am asking for your guy's input. Thanks!!

I run an 89 j arm bike and love the uniqueness of it. If you aren't planning on jumping a lot, a j arm bike will be just fine. Not to mention the front end is a bit lighter. I use mine for duning and have had stellar machine build me a set of j arms that are second to none in reliability and quality. I personally would not second guess my front end against an a arm bike by any means, but that's just my opinion. Others might disagree.

Thanks Guys! But yea I wont be jumping this quad at all. It would just be strictly for a flat clay track so I can keep busy during the summer between Ice Racing. Do either of you, or anyone, know of some good aftermarket dealer that sells or makes quality j-arms?

the J-arms are still good suspensions..... yes they ARE lighter.....that's why alot of guys wind up liking them for more of a drag style platform. Also the brakes are slightly bigger and they take different pads than the later model bikes.......i don't know they're availability so that could play a factor into turning it into a racer.

Only 1989 and older bikes have the bigger brakes. 1990 models have J arms and the late style smaller brakes. J arms are lighter, but they also bend easier andthey wear out bushings quicker. I have an 89 and 2 97s and also have had a 96. I bent both upper J arms in seperate incidents on the 89, we bent one arm on the 96( wife crashed). The stock plastic bushings wore out within a year of buying it brand new, I have never put bushings in the A arm bikes. The brass bushings I got from Toomey( only ones available at the time) hold up VERY well.

Call Stellar Machine, tell him your a BansheeHQ member and he will take care of you. He is a great guy and his product is top notch. You won't find your self bending a set of his J Arms very easy by any means.

 

Here are a couple of pics of mine. +2+1 with hd ball joints and yfz tie rod ends.

the dentons i have used needle bearings instead of bushings.

 

i also really like tims ( stellar) desin of j-arms with the yfz tie rods and the big ball joints that a rock solid front end..

 

i have a PILE of BENT upper a-arms out there. they bend just as easily or easier than the j-style for sure.. the problem that i see is where the ball joint is mounts compared to the actual a-arm they are on a flat plate thats kinds pis poor welded on i bet a lot of peeps are riding bent a-arm bikes right now and probably dont even know or even care.. if you look at the a-arm where the ball joint is there will be a slight bend or peeling paint and rust there from a harsh landing.

aftermarket j-arms or a-arms even WILL not have this problem at all.
