[71Dragtruck]

Alright to help you out we need to get a few clear answers, you mention 295 slicks and BFG drag radials? Have you tryed both? BFG drag radials are nothing like slicks and in no way will ever hook up like slicks. These drag radial guys you hear about running them have nothing close to what your trying to hook up.

That being said, have you ever ran at the track with a fresh pair of actual slicks or even a DOT aproved slick ( Quick time Pros, or ET Streets )? if you have never tried that type of tire at the track give it a try before spending a bunch on suspention upgrades. Like I said in my other post I've seen guys with alot more motor then your running at the track with a LWB truck and leafs hook up no problem.

If your determined to change out the rear suspension, then try to find a coil setup parts truck and swap it out, but I have a feeling your still going to spin those BFG's, if it's a drag radial you have your heart set on running then at least step up to a set of M/T drag radials.

Either way good luck with your project.
