How do you get what to stop?

As far as spinning both rear tires you need to replace the current open differential with either a limited slip differential or a locker. In a 4x4 a locker is a very good way to go. If you go with a locker then a Detroit is the best but probably most expensive route. You can also buy a Lock Right or EZ Locker, these are about half the cost of a full size locker and only replace the spider gears and the side gears and keep the original carrier. They are not nearly as durable as a full size Detroit locker but they do work if you're careful with them. I have a Lock Right in the rear axle of my Blazer and haven't had any problems with it but I rarely take it off-road and only have 31" tires.

There are other ways to "catch posi" but a locker or limited slip are the two most common and most effective ways to distribute power to both tires.

You can't really count on spinning both tires with an open diff. You would need a lot of horsepower and most likely bad traction.

Go to a posi and you don't have to fiddle with it.

In an open differential power is sent to the tire with the least traction, that's just the way they work because of the nature of their design. If you want to distribute power to both tires then read what I wrote in my previous post.

Usally in an open differential the passenger side tire will spin so if you get it spinning good crank the wheel left and it should burn posi, but it may just unload the driver side. As for the gears most people think 3.08s are to high but my K10 will burn just fine with them. I also wouldnt recemend doing too many burnouts if you have a 10 bolt.

P.S. Quik Lok $279

put an air bag under the right side leaf spring, blow it up a little, you'll spin both tires. it preloads the suspension

Why are you worried about burnouts anyway? Light truck tires aren't cheap and you just want to burn your tires down and have to worry about replacing them? I don't know about you but when I was 16 I couldn't afford a set of tires. Heck, even now I don't want to shell out $300 for a new set of rear tires just because I fried them off...

a friend of mine loves to smoke off the tires on his '94 GMC 1500, buys used tires, now he just recently was given a set of what he called " nice " tires, they were/ are worn out daytona's just legal enough to pass inspecion.

Burnouts are cool

Some things never change. I remember a guy, friend of a friend, when I was in high school, (in '78), who had this beat to death,not a straight panel anywhere, 68 f 250 long bed 4X4. His dad was a guy who, ( i think), did a little dealer sponsored racing back in the day and he had an extra 427 side oiler with all kinds of go fast stuff that they put in that old f 250. It had locker in back, limited slip in front , big gumbo mudder tires ,at the time I think 33" were HUGE and a 4 speed....

I guess dad was well off, because...
Zoom, (we called him zoom because he wore these thick glasses), would put it in high 4wd, 2nd gear, turn up that 427 to about 4500, dump the clutch and bury the gas pedal and it looked and sounded like the world was coming to an end, smoke and screeching and all those big tires frying and that big gnarly truck drifting and sliding every which a way and rubber flakes raining down like black stinky snow.

He so many sets of 4 wheel fishtailing and sideways black burnout marks in front of his house you could not see virgin patch of pavement. When things were just right all of the tires would not make hardly any sound at all except for this zzzzzzzz sound . But that 427 sounded sweeeet


That was a sight to see And that old ford lasted for a bunch of years until all of the running gear was just shot.

Guess what the guy does today....Tester at underwriters laboratories doing failure analysis.


Later, mikey

WHAT you don't remember 16 ? I do and I'm 45yrs old, my 1st car a 67 GTO 389 & 3x2s & a 4 Speed in it when I bought it, it was a used car of course, it was 10yrs old. I had no late model 4x4s. I bought the car from summer jobs at age 14yrs. my uncle helped me for 2yrs. it had cragger ss all around and N50s on the rear when I bought it. 8mons after I turned 16 I put the 6th set of tires on the rear and a fresh 400 a couple mons later. this was burn outs and getting them stock tires Hot to race. I funded my own fun. but in 14mons I learned as then I had a bank loan for the new 400 & clutch & detroit locker ect.



prob would not do it that way again if I was 16, but I had one of the fastest cars in my small town of BBC 65 & 66 impalas & Chevells and a 401 nail head 66 Buick GS 4 speed car & BBC & SBC Camaros a few mopars ect.


Them were the days


yeah I hate buying tires now too, I think I hated then, but I was young & dumb and keep it up, till tell I had to speak to a loan officer with my grandpa as a co signer, then reality hit, I paid my notes off and still bank there today, of course the banks changed names.........

I had a 4 cyl Isuzu Trooper when I was 16. It was never able to do a burnout. Although I did try to take it offroad a few times. With a truck I'd much rather have to replace a set of tires because I burned them up trying to hill climb or some other 4x4 related activity.

Put a limited slip center carrier to spin both tires.

If you what to spin those 33's faster then you will need more
low rpm torque. A higher stall torque converter and a higher gear to make up for the 33's will help a lot. Try some 3.73's or 4.11's to go with the 33's.

A 28 inch tire with a 3.08 gear is like a 33 with a 3.63 gear.
A 33 with a 3.08 gear is like a 28 inch tire with a 2.61 gear.
In other words, you are asking a lot out of those 3.08's with 33's.

Are you trying to do a brake burn (as I call them?) if so get the tire(s) spinning and try letting off the brake a bit that usually gets them going faster. You could back off you rear brakes a little also.
