Are the stock Toyota Tbars 23.4mm? I am running Sway-a-way 25mm. I havnt tested the flex. I should try on a curb or something.

That is what I was thinking. Plus I think 4runners look good with a slight forward rake to them. Also makes them sit pretty level once loaded. I say try the stockers and maybe just a slight crank to them.

Yep, even if you switch tbars and crank to the same height, I doubt it will be perfect, so you would need an alignment anyways. Or you could try the do it yourself alignment I am pretty sure elripster has a writeup on how to do it. Might be worth trying if you are short on $$$

okay. Ya i tried reading a DIY alignment thread earlier and i just got lost. money really isnt a problem right now so im gonna get it aligned. Plus i have wheeled it pretty hard the past 6 months i have had the lift and i dont think another alignment will hurt.

The smaller (stock) bars will travel farther given the same load. So if the rim-to-fender distance is the same as with the Downey bars, the suspension will flex more. In addition, if you think through all of the pivot points and lever arms, you are not changing any of the geometry that affects the alignment if you only change the T-bars and set them so the rim-to-fender distance hasn't changed when sitting on the ground. Pretty sure the rest of the engineers on this forum will agree with that assertion. HTH.

Another way to put it is that the smaller the diameter the bar the lower the spring rate.
