Welcome to our newest sponsor, Total Load Control. The website is www.totalloadcontrol.com and here's some background from their website. Total Load Control is the patented aftermarket air suspension system with two 9-inch, dual convoluted Goodyear® Super-Cushion® air springs located below the frame above the rear axle. When it comes to air springs, bigger is better and only TLC uses 9" air springs (for Dodge RAM 1500 & Chevy/GMC 1500). http://www.totalloadcontrolsuspensions.com/totalloadcontrol.aspx ---------- Post added at 12:10 AM ---------- Previous post was at 12:07 AM ---------- TLC John will be here to answer your questions about their products.
