If I didn't state it strongly enough: Sway Bars Rule! On the Straight, In Curves, On the Campsite. Only mod I know of that helps Underway OR Anchored!
I looked in my file and see where I bought 7008 Front and 7180 Rear in FEB10. My papers don't have Price, but I think $400 or a pinch over for both. Paperwork says "Winter Sale 10% off Free Shipping" and the bars were shipped to me direct from Hellwig.
The Specs, Diameter and Material, are same for Hellwig and Roadmaster. From instruction sheets, I like the looks of Hellwig's rear bar mounts better than RM's. The RM front bar for the '92-'07 models had prettier mounting hardware than Hellwig, but my Hellwig hasn't as much as stumbled. The difference is PRICE. Discounters like SD can set you up with both bars for about the price of one Roadmaster bar.
