I like it. Can't wait to see the parts. Sounds like 2/3 cost or less of rough stuff?

I'd probably run 3/4 hiems that I already have... I'd still love to try the Toyota thing but I never see those trucks. Maybe I should try cruising forums for ppl doing solid axle swaps.

i broke a 1" bar with aluminum arms, so i dont think its the spline issues people say- i think thats from loose bolts.

i went to 1.25" bars, they seem to be most common. 

steel arms, ill add aluminum extentions to seem pretty beefy.  having a chart and known name of bars is nice.  2 of mine are gun drilled and light also.

Interested in pulling torsion bars and A arms?

Can you get me a length on the torsion bar so I can see how it might or might not fit for me?

completed on 572 and 928.

passed dock tests and rip around shop tests

matts car no longer has torque swat after throttle down, keeps pretty flat in loose turns, great improvement on pavement turns.


both the cars could still go a little stiffer we think, but a good start.  3-5 bolts and 2 min to change bars

Sway bars did work and handled better than many of the other cars at KY with currie and PAC units. Smike you outdid yourself on that find.

a little bit of thought and engineering after reading how others have failed improperly using the same components goes along way

they really were awesome.


wish mine looked less farm truck though lol.  matts turned out pretty nice

are the arms that matt has something "stock"? they look super sharp. I need to take a look at how those things came out and try to replicate.

pair of 14" arms for $120, 4 bars for $230 seem decent?

I definitely don't see $20-$40 bars....

ya i saw the 4 bar set, you can do better getting 4 separate and he will combine shipping.  longer arms looks like a good find.  Matt and i wanted interchangeable parts.
