I just picked up a 2002 HD F150 w/ Supercharger. It has 60k miles... The truck seems to have a very quick engine response when it is moving, but from a dead stop it won't spin the tires when I floor it. Is this normal? It does take off quickly... Is there some sort of anti-slip rear end or do I have a problem? My older F150 with a 4.6 spun the tires accidentally all the time...

I have a 2002 H. D. with the 03 lighting upper pully, S.S. full lengh headers, preadetor chip. It also does not spin the rear tires from a stop. These trucks have limited slip Diff.

 

Must be the wheel base and extra weight. I've had a 99 Lightning, and now a 03. Both SMOKE the tires from a dead stop.

 

Depends,

I found the lightning to be easily able to melt the tires...

I've never driven a HD, but with sticky rubber, a tight limited slip rear end, and good pavement, I could see it not spinning off the line. If you stabbed the throttle vs smoothly going to WOT, you'd have more of a chance.

The lightning's auto tranny is setup a little stiffer, so more abrupt power is sent to the rear wheels. The HD is a little smoother, so that power transfer is going to be softer/smoother, making it "difficult" to spin the rear tires.
