Superior Engineerings A-Frame

[steve patrol]

Just looking at an oldish 4by mag. One of the Adds in it has the Superior Engineerings A-Frame. I looked on the superior site and cant find it? Where these a flop or are they awsome?

Cheers

yeah like he said!!!

we found though testing that it isn't the otp arms at all that limit flex, it is generally the lenght of the lowers that seem to make the biggest difference. Not only to flex but to the way the rear transmits power to the ground. using a long arm kit we can easily use ALL the stroke of 18" travel swayaways, the GQ comp truck ramps just under 900rti on a 30 degree ramp, but still drives very well at high speed. Robbie marshall has a set on his winch truck and he has won just about everything this year in it!!!

I think i saw the same add as mentioned earlier in the post. It talked about the A-frame as an eliminator for needing a rear panhard bar, how do they handle on road, and are they still available? Wizard performance alse has one and it has got me curious

As one mad engineer stated the problem is not the top arms but the lowers, "bolt in "a- frames create a shit driving truck when they are using the original mounting points as the are way to short.
The only benefit of a bolt in a-frame is you wont hit the panhard rod, either do a full custom 4 link setup ( with long arms ) or go long arms with a panhard and upper control arms.
Most guys now do not use bolt in a-frames anymore they were designed in the 90's and thats where they should stay.

will work well if you make a decent a-frame and use custom mounting points, as the convergence point is not ideal using the std pivot points. Also the roll center is very different, as well as changing the roll-axis. Spring rates must be changed to complement or correct any handling issues. IMO the 4 link with long lower arms is quite a good overall setup. no need to make it any more complicated.
