Hello; thanks for providing this forum.

Here's my question: 2000 Lightning with the upper and lower pulley modification. I'm getting belt slip- particularly on 1-2 shift RPM change and 2-3 RPM change with the shift.

Anyone have some special tricks or secrets to avoid the belt slip? There seems to be some after market pulley/tensioner systems which are rather pricey; are they worth the dough or just another unproven mod. that wastes cash?

Thanks, Performancenut

 

Jeeze- you mean no one has a reply to this post? Seems this is a somewhat common problem from what I've heard.
