From my understanding, the 4.10s are LSD. (am i wrong.) W/O looking at my axle, can neone tell me if i have LSD. Im under the assumption that i do, but im a little confused now...because it says 4.10 regular axle. below is a link to the window sticker:

I have 4:10's with no limited slip, its an open diff. power brake it and if you do a one wheel peel, then you have open diff lol

 

your prob going to have to read the tag if it has a ls on the tag then its a ls diff

 

Did you look at the sticker that on the door when you open it up, look at the axle code and tell us what it says.

 

was just about to say that..

do a small burn out and you can tell..

and I think on the axle tag it will say like Ls or something like that

 

Look on your door sticker under axle could. If it says R7 you have a 4.10 LS if it says 97 you have a open 4.10

 

Look on the axle tag too....it'll say 4L10 (lmited slip) or 4 10(open). Or jack the rear end off the ground, truck in neutral p-brake off, and spin a tire. if the other side spins the same way your spinning the tire, you've got LS. if it goes opposite of the one your spinning, it's open.

 

^^^ damn shane beat me to it

 

Well now i know, i need to change my dang sig! its jsuta regular 4.10, aint that a bi@#%. its says 97 on the sticker inside door. that just makes me wanna find a limited slip diff now! stupid crap!

 

well hey, at least you got 4.10's! alot of these 06+'s are 3.73's.

 

true, time to find a LII axle or something...lol, nah i have more importaqnt things to sabe for, my axle works just fine. It got me through the sand and everything just perfect. i dont offroad enough to have to have LSD. but it would be nice. mayber ill run across one one day for a deal.

 

Mine has 3.73s and open.

I would much rather be in your position. I would also rather be locked than geared properly. 1 wheel peel ftl.

 

ya im also 3.73s i would gladly take your 4.10s

 

i have the 3.55 LS. what is the advantage to having 4.10s?

 

Feels like you have way more power. 33's+ w/ 3.55's is a no no

Mine has a 97 axle code as well. Still feel lucky considering mine is a bare bones reg cab edge w/ NO options

 

Thanks! i'm not planning on lifting my truck or putting big wheels on it. would it still be worth my while to invest in 4.10s?

so far i have K&N and a cat back exhaust and plan on doing headers and pulleys when i have the cash.

 

mine says R7.. but i have 4.88's now :) ftw

 

Just keep your eyes peeled for a lunchbox type locker (Lock-Right, No-Slip, Aussie Locker, etc.) on ebay, craigslist, etc. They replace the spider gears in an open differential. More traction than an LSD, cheaper, and only takes about 4 hours to instal without any special tools.

 

I wish I had an open diff, I kinda do because the LSD is so worn out. If I did, there would be a lockright in there now. As it is, I have to find a new open carrier.

 

You can get rebuild kits for those for $62 on ebay.

I have the 3.73 w/ LS, but sometimes I wish I had the 4.10's...........heck I even wish I had a 4.0L LOL

 

AAAAHHHH 4.10'S LIMITED SLIP

 

Thanks, but the axel is being ripped out in about 9-10 months for a 9 inch rear. For what I do, a limited slip is, well, too limited. I would rather know that if one tire is in the air, then the one on the ground is going to keep going.

But for someone who drives their truck more on the road, and doesnt want a locker, then you cant beat the good factory L/S

 

But a pain in the *** for daily driving with a manual transmission.... ask me how i know....

 

I have 4.56's...........wish I had something else.











Just kidding lol
