Shift kit for 02 F250 7.3L Single cab Long bed

I like this little kit a lot. Makes for quick firm shifts but still smooth enough that its not a bother even in the lightest powerstroke like mine. I enjoyed installing it, of which was easy to do. Changed my trans filter and fluid during swap. I think its a must for all, helps against premature clutch ware from long lazy stock shifts. Well worth the money!

I installed this about 2 weeks ago not really knowing what to expect. The results did not seem noticable at first but I got on the gas hard today and wow! no hesitation when shifting, and shoots threw the gears hard, but not too hard. Install was pretty easy took about 2 hours.
