4-lo is the shit

I was just playing around yesterday, and I got curious, so I put the truck in 4-lo and idled out in first. Wow, the gearing in 4-lo is ridiculous...

First gear is 3.95
Final drive is 4.10 (4-banger)
4-lo gives 2.56

3.95 * 4.1 * 2.56 = 41.5

Engine at 1000rpm
1000rpm / 41.5 = 24.1rpm at the wheels

Tire circumference of 95.7"
24.1 rotations per minute * 95.7 inches per rotation = 2306 inches per minute

2306 inches per minute * (1 mile / 60360 inches) * (60 minutes / 1 hour) = 2.29 mph

The truck was definitely crawling.

 

LOL.... or you could have looked at your speedo to see that you were going really slow

 

Heh, it actually didn't register accurately that slowly. Although my math doesn't account for slowness due to the weight of the truck, etc, so I probably didn't even go that fast.

 

lol welcome to using the 4 lo club. It is awesome lets you do this http://www.youtube.com/watch?v=ylxssLL7ijs

 

It's also great for crawling down steep shit without even touching the brakes!

 

indeed it does lol, a lot of stuff you dont need the gas either haha

 

sorry I got lost. I would'nt know what yall are talking about

 

Wow sounds like someone has some time on their hands to do math LOL...

PS I love my 4lo

 

Used mine last night for the first time, switched it over while in drive at a stop and my truck started beeping like it was going to blow up, then i remember it needed to be in neutral after that it worked like a charm and was a lot of help coming down

 

lol beat me to it....

Ask Fire931 about 4lo if you want to know about it in our trucks.
