Ok say u have 2 finals that are nearly the same cept one is on the Hi side (2nd) other is Low (4) whats the best option ? ((5 spd))
 
I use 2nd HI with 4.10's & 33's. I pull against guys who use 4th low & usually put 10ft on them or better. Most of the tracks are hard pack out here though. I haven't run 4th because 2nd has worked great for me. I've seen too many guys breaking parts & losing clutches to 4th.

I always hear the exact opposite. Everybody always says you break more parts on the high side.???
 
i think it depends on alot of factors. track, rear gears, tires, and turbo. i have seen the same truck hook back to back and droppin to 2nd made about ten feet different cause it bogged and pulled instead of gettin under the huffer.
 
I can't see any reason to run the high side if the finals are the same. You hinting at friction in the tranny, or more efficient transfer of power?

I know zero about the manuals and such.
4 low: extra friction on some shafts because of friction, some loses through the planetary on the tcase.
4 Hi: More losses going through gears on the tranny?


My vote is 4Low seen too many 2nd gears wiped out.
 
Yea Dan yr getting to what I'm looking for , if any HP or lets say were is the most power loss ... I busted 2nd gear 2 weeks ago and got the counter shaft hate to do that again .. I have a set of gears that would turn my 4low into 2nd and after last night I think thats the best final for me, and if I need just a little moire I can throw on some 315s to gain some MPH

Oh, I've heard the same as well, but I'm not buying it. I've had these transmissions apart & transfer cases as well. You are putting more stress on your clutch, input shaft, u-joints, turbo, everything by grabbing big gears. I think more revs combined with smooth launches is key to a good pull.

I have never had a failure 2 years of big gear hard launches 5000+, 33" tires single/and dueled up out back 35" tires and 36" tires running on the best tracks in the country KY,IN,OH.

better be knockin on wood or something! Last time i said something like that i shattered 2 axels LOL
 
if u can run the rpms. run 3rd low i run it at 5200 rpm. its easy on the driveline and clutch. the high side of the transfur case is week in the dld and dhd but if u put a 271 or 273 in there you can run the high side but the 2nd gear is a weaker gear then 3rd or 4th

The question here is are you looking for insane amount of R's or ground speed...........I could pull in 1stL if I did not care about ground speed.

whats the difference in wheel speed 5200 at 3rd low is about 30 to 31 mph and 4th low is about 34mph with 4000 rpm cause no street truck or pro street truck will turn big rpm with that big gear so why wouldnt u run a smaller gear with more R's and not snuff the charger or if u need to get out of the throttle u can bring the little gear back up
 
Strongest possible setup

5 speed = 4th low

6 speed = 5th low

Driving with the mainshaft is like having direct drive. No matter what gear you pull in the countershaft is always spinning so if you are looking for least amount of drag, I don't know what to tell you.

with the Hero Gear (4th low) its hard to keep up with big chargers on r red dirt tracks now junk tracks that suck i can understand but i like twisting the motor to the bigger rpm
 
Depending on the charger you are running, most of these trucks probably run better around 3800-4500rpm than at 5200rpm.
