Holy hell

I thought mine was bad 2.1 with 3.23 open diff and 31.5" tires.

Cam is 224/228 581/588 on 112 ill have to look fir a time slip for the 60 foot. Has 373 gears that is gonna get 410s sometime I just expected more of a gain

my opinion that gear swap would be a waste of time in a big truck, either keep the 3:73s or go 4:30s for a better improvement

so what you guys are saying that 4.10's show a considerable amount of ET drop? I have 3.42's running 13.40 at 101 on a 2 second sixty foot with stickies.. whats the usual gain with 4.10's? Would i lose trap speed?

That depends on the truck, but generally going from 3.42s to 4.10s will net awesome gains especially in the seat of the pants range.

To the OP you need to drop some weight, add More stall, stickier tires, and some 4.30s.

Is it traction problems you're having? That is a pretty terrible 60 for that ET. Not being rude or anything just trying to see what the problem is.
