Not sure how to describe the push, maybe it occurs when the trailer sways.

I am thinking I need to get the rear higher when towing, helper springs or air bags.
I do remember after I got the air bags on the Jeep, the sway decreased, but at times it would occur.

Tom, I can always use engine parts, I have no need for the suspension parts. I will be at VIR for the National (working), and probably driving at VIR for the Double in May, you planning to attend one of those?
I am sure we have meet and talked at Road Atlanta and at the Runoffs (Topeka?).
