Any difference on good roads? Yeah a steering stabilizer helps with bump steer but I ran with out one for years and didn't have an issue, and that stock one is more than enough for 33's

 

This is what I'm curious about, Jeek. A wider tire, particularly an MT or the like, will add to the darting left and right. There's much more tread contacting the road with a 12.50 wide tire, therefore grabbing any imperfections in the road and sending you in that direction. Sure, if your stabilizer is leaking and in need of a replacement, go for it, just don't expect it to be the end all.

 

I'm running a nitto mud grappler 35x12.50 and 2.5 inch lift and roads in la aren't the best. I get some bump steer when I hit like a huge bump in the road but that's about it. So I can't think of anything else other that something is loose down there or maybe a tire balancing or air issue
