I cut a 1.5 with cooper discover hts 275/60/20 I believe. Aired up to 50-55psi as well

I wish they had 3.42 for the Dana axles. Or do they?
Besides mph... what? Less likely to spin off the line, slower 60ft? but gain on the back half? Would it be harder to drive on the street (spool/smoke controll)when i occasionally do take it out?
I have been wanting to do this for a while but something else always breakes first.
I think/hope i have those issues straightend out and want to start planing my projects for my winter months
With 3:42 gears what tire/wheel combo do you suggest for drag racing and maybe the occasional trip down the road?
Would it be different for 3:55s?
you will pick up et and mph. If you watch the pro street guys, a lot of them(and us) shift to 2nd really fast in effort to bug the engine and make it work harder. The higher gear is doing the same thing. Also, go with the tallest drag radial you can get.

NT420's FTW I've cut 1.61 60's with 305/45R22's...
Great info, thanks!
On that note, what is the tallest drag radial out there? It seems sizes are very limited.
Shifting early, but when are you locking the convertor?
thanks dave...looking for them now..........
We lock in 2nd. Some guys have tried locking in high 1st, but there is not mich gain for the return in carnage.
If you're gonna change, might as well do 3.42's if track times / mph is your ultimate goal... Aron Nick loved his truck after the 3.42's.
If you want to run low 10's or 9's someday, I'm sure 3.42's will keep you from running out of gear and keep you in the meat of the powerband...
M&H makes a 390/40/17. This is the best tire out there for the 3rd gen 4wds in my opinion.
My crew cab truck cut 1.51-1.52 almost every time with this tire. I tried MT drag radials also, but they didnt do any better the the nt420s. It would do high 1.50s on a very good track with the 420's, but had to run pressure way low.
