Hey all! contemplating getting a 4ws Express with 3.92s....

Can you race a 4x4 truck in 4wd (4wd Lock) at the track? Will I break anything? I was considering a 3200 stall converter with 4wd on and I wouldn't have any traction issue at the track.....is this safe?

I am not new to drag racing but I've never owned a "true" 4x4 before. I know diesels always drag race in 4wd when possible.

Racing a stock vehicle always has that potential, launching may snap something. I don't think the engineers at Mopar thought about these trucks being raced off the lot.

I can crush the local R/T's with my 4x4
3k stall and 4 shorter Drag Radials, 3.55 gears

In fact I can even run door to door with SRT8 Jeeps.






I only use 4WD when track prep isnt 100% and traction is questionable.
and even then I only use 4WD Auto (AWD mode), that only engages front driveshaft when rear slip is detected. ;)

Thanks a lot MB! :smiley_thumbs_up:

Without the shorter tires and 3.92s, do you think I could hang with a stock R/T in 4Auto?

Reg Cab or 4 door?

Not likely without DR's

My effective gear ratio on DR's is 4.30:1
and I drop 120lbs on lighter 17" wheels and DR's

every 100lbs will drop your ET by a 10th,
and R/T's are featherweights at 300lbs less than my RCSB 4x4
R/T TC is a 2600 stall, stock Ram is only 2300.

A great launch in 4wd really needs a higher stall torque converter...at least 2800-3000

Sorry, I forgot to specify... This would be a RC/SB with 3.92 and limited slip diffs.

But here's, the thing This truck will be a commuter as I drive 70 miles a day to and from work. So I want to know if I can hang with an r/t on the street with street tires in 4wd? I read a lot of your posts and see your truck is more of a racer/weekend toy sort of thing and I can't justify slicks for the 2 times a year i go to the track. And I promise, I'm not stalking you! :LOL:

You will only beat an R/T if traction is bad...gravel,rain,snow.

an R/T is 300 pounds lighter with a higher stall and 4.10 gears and will dust you on clean dry pavement.

sorry ;)

Bummer....guess I may have to go the R/T route! :thk:
I have a Trailblazer SS right now and me ego won't let me get anly slower than high 13s or low low low 14s (which is why if I can't get a ram to run those sort of number, I'll just get a challenger!)

Are you looking to run your truck in 2wd only??

I use 2WD when track prep is perfect, usually a 10th quicker
Only switch to 4wd auto for my next run if my first pass in 2wd spins
...it doesn't happen often with sticky DR's when they lay down fresh traction promoter.

4 auto is just insurance for bad track prep when you have an open rear diff like me.
