I have pulled several times, but always used low range 3rd. got 1st place 6 times and 2nd 2 times out of average of 6 trucks each time. Just would like some feedback about high range or just stay with low. Sometimes I can go to 4th in low. Took the lift out since pulling. Always pulled with 265's or 305's, this week going to try 315's Toyo At's on stock wheels. Just wandering.

low range

you cant go past first in high...tcc wont lock in first.

did I mention low range?

I use 4hi 1st gear works great for me. I'm always in the top 3 in local diesel.

X2

I think your finishing order answers that for you. low range 3rd gear.

I was wondering the same thing, becaue i pulled the other night and 4lo 3rd gear seemed to low. My truck sat at red line the entire pull and never really bogged. Plus it seemed like i didn't have enough ground speed. Guess I should try 4lo 4th gear next time?

Can you manually lock the converter 1st high?

I would suggest bigger and better tires.

You can lock the solonoid, but it wont do anything until the trans is in second.

x2 i went with sts's and it uses up all of my power compared to my old 265 bfg mt's

Pulling in High range breaks parts. I have the two peice output shaft to prove it!:eek:

I have probably between 30-40 hooks on my built ally in high range 1st gear with no problems. And I almost always beat the guys using low range. I think the smooth application of power that the torque converter in 4hi 1st is a big advantage over using 4lo and shifting 2-3 times in a pull.
This could be a different story with a ZF thou????

Are you saying you're doing this with your new motor or the old one?

No the old one. Sorry for not being clear about that. My guess is set-up is more important in my case. There is a guy with a 3.0duramx who was using 4hi 1st with good results but i think he is using 2nd through 4th in low range now. Our tracks tend to be pretty loose too so i guess that would change things consideribly compared to what you guys see.

I agree with what you're saying.

I talked at length with ATS about first and the short story was "wanna burn down your C1s, that's the perfect way to do it."

You hear of people doing it now and then but usually you find out that it's a 500 hp or less truck.

Mat,

Isn't pulling in 1st high a disadvantage also due to not having converter lockup (lost power), or has that been remedied?

No, 1st gear still does not lock the converter.

With that much slippage it would come down to just the right speed to get a sled going just right to be close to the front...like a real light setting you'd use for a box-stock kinda class.

I would suggest bigger and better tires.

I have BFG's mud terrain 285x75x17 tires. Can't really get any bigger tires to fit unless i put a lift on. Plus i don't pull enough to justify tires just for pulling. Only a hand full of events around here.

I don't know if i put the loud peddle down to quickly and it caused them to spin the whole way or what the deal was. I'm pretty new to pulling. Is slowly getting started much better? i'm thinking next time i'll let it shift into 4th if it can.....

I have been interested in this topic for a long time, and eventually I'm going to need help too. I read and read and read and I have the impression basically if your running stock, go 4 lo, 3rd gear or so, depends on the track obviously. If you have a tune maybe then you can get away with 4hi? Plus I am under the impression that 4hi is just a front and rear wheel, and 4lo is actually all 4 wheels?

i have a 500rwhp tune and have never attempted, tried or thought of 4hi if that helps you out. nor will i ever try it.

Just tried 4lo last night worked out good. I grabbed fourth about half track. Can't wait to try it again tonight!!!

Thanks, yeah I thought that probably 4lo was the way to go

I'm still quite uncertain. Curtis and I both tried low range last night for the first time. I know he liked it, I think I shifted to 4th to late in the pull and it hurt me. I would like to do back to back pulls in 3rd low, 4th low and 1st hi. I would like to hear from someone who has actually done this!!! I just wish every didn't say that 4hi 1st is hard on the trans and I might stick with that! Has anyone done back to back runs? Curtis and I both saw 500 rpm drops from 3rd to 4th and we both spun 3100 or so in 4th but I still question if I pull better in high range...

If you are on a sled that comes out heavy and you just nail it with mud terrains, you can "chunk" the hell out of the track and go nowehere. You'll hear crap hitting the fenderwells and it feels like you're in slow motion with no sled speed. Because you are!

For a lack of a better term, what you want is "surface traction" where you stay on top of the track and stay coupled to it.

Here's a retarded analogy:

Imagine the track as a pine board. Tires that have good surface traction behave like a belt sander. If you don't hang on to it, it will couple to the board and run right off the end.

Mud tires kinda behave like a planer or circular saw. Instead of staying on top and gripping the board, they tend to punch through it and dig holes.

This is why the AT tire comes so highly recommended for normal conditions. Obviously if you're in a swamp, they're no good, but most places I go any more won't run the pull if it's a mudhole.

There is no difference between 4Lo and 4Hi except the gearing in the transfer case.

You're also looking at the gear choice incorrectly. Having stock power means you probably won't hurt the trans as much and going high range might not do anything but heat the trans fluid up.

However, with a big tune, I think 1st-high is a recipe for frying your C1s. Plus you get no torque converter lockup.

You guys nailing 4th with stock trucks, just letting you know, that's a light sled. It's probably allowing you to run 1st high without problems, for now.

We have a lot of stone dust tracks up here. On a good clay track I doubt my current setup would pull fourth. Just saying it felt like the truck worked better.

So your saying stick with the 4lo approach?

Oh, hey, if it felt better, I'm not going to argue with that. You have to find out how your truck pulls best and frickin' run with it.

Stone / gravel / dusty tracks are a whole different regime than clay, and no doubt play a huge role in how to set the truck up and how to drive it. Believe me, I've learned that one the hard way. :D

4 hi is the way to go for me never had a problem yet

The way i see it is there is no shifting to break things & if you losse your hook you can play with the peddle to get it back with out shifting gears

My truck has 150,000 miles on a stock 6 speed trans works every day pulling a 9 ton trailer and has been truckpulling for 3 years
