I'm saying MY stock torsion bars, shocks, etc. work just fine for me......
I don't know of anyone who has replaced their torsion bars with the H-D ones from Indy4X, & I wheel with 20-30+ of the membership here.
Don't get me wrong, I highly recommend Matt & Indy4X every chance I get, I think it only logical to support the ONLY vendor in the country who is interested in bringing a wide variety of aftermarket parts to a very small market.
I'm just sayin' ALL that stuff isn't necessary to be VERY capable off road.
