Default drag racing

i was wondering if it would hurt anything to race in 4L instead of 4H,that way it jumps harder.and also if i would get enough speed,anybody know what top speed is in o.d.4L? thanks guys.

No i would stay in 4H, 4L is way to low of gearing to be drag racing...i know my truck in first low will top out at like 8 mph and thats at like 3500RPM.

And 4L it would be really hard on the Transfer Case..

i dont think the 60 fters would be as good as you think, you would be topping out each gear so fast especially with 410's in Low...
