I can top that! I bought a pair for $20 at Carlisle last year for my 92 D150. I race it occasionally and didn`t want to spend the $ for Cal-Tracs, I couldn`t leave over 1,600 with out wheel hop and tire spin. I put the bars on , clamped every leaf in front of the rear housing and replaced the air shocks with a set of B body Ranchos I had on my Dart when I had S/S springs and now I can leave at 2,000 with out spinning. It only runs low-mid 15s but its not spinning anymore.
