Yep--I put one on my 97 1500, and although I can't say that it improved much of anything at highway speed, it DID(for me) improve the low speed manoevering around parking lots and especially when having to do a 180 turn on a narrow road.
I just installed one on my 1500.I got it on ebay for $56.00 and free shipping.I have not really noticed any differance,but I have not had a chance to really check it out yet.Installes in about 15 min super easy.
I have one and it helps some at slow speed turning. Not hard at all to install but don't force fit it. If it does not want to fit without force then sand it down a little until it falls into place and then bolt it down.
