I want to know if the limited-slip diff's, built by Earl/Chad of Indiana, are worth the money? Like to hear about the pro's and con's about the work. What is cost and what is involved of doing the job? Any info will help, Thank's

From what I understand they are built on the same principle as an early 1086 International, which did not hold up very well, however I do not know anyone personally who has run one. Therefore I'm not going to criticize them. I do know that Paul Marlatt builds a limited slip that costs about half what theirs do and it will hold up. That's my .02 cents. Jim

Its not based off of any production past or present. Like I said, 850hp+ and not break it. Chad

Yeah Joshua they are not worth the time or the money. What are you wanting to put it in. I might also have a set of tires around here on the farm that might be some help.

Well, im gonna respond to all 3 of these posts all in one and thats all im gonna say to the replies,,,,, ,

Josh, we have them,Im Chad in the ad,,, Earl is my father,,, and so far,, we can hold over 850hp thru our unit and not break it, it doesnt mess up any bearing tolerances which tightenting up the spiders (which is the old fashined way but they break) do. We stand by what we sell, satisfaction guarenteed on that. Some models are more difficult to install, and some install very quickly upon reassembly.

Now, to the replies left,,,, Good tires are a must, good measurement is a must to fine tune a frame to pull, but all the time, one of those perfect wheels slip and well,,, your finished. keeping both wheels turning together while pulling,,,, Most may never understand how or why something works. I dont think these fellas have ever seen anything that has came from our shop, nor can they give an opinion of how we do our work. I will say, that the some of the top pullers in the leauges of antique puling are using our differentials and the difference is astounding. Good tires,,, is a must have,, add the limited slip and put the power to the ground, and I dont care where you get it from,,,, trying is one thing, never trying, and putting others down cause they did and jelous cause they dont have it,, is another. JMHO,,,, have a nice day, and our phone is 574-893-7437 ask for Earl, or Chad. ChadS

I'm not in the limited-slip market and I guess it doesn't really matter to me, but what sort of a limited-slip arrangement are you selling? I mean what are the mechanics of the unit? I'm familiar with most of the styles of limited-slip differentials used in automotive axles and in MFWD axles in tractors. Is there one specific style of unit your product is modeled after? Is it a clutch-type? Torque-biasing? How does it work?

Depends on what brand of tractor,,, All of them except the JD's are a dry clutch type, fully adjustable, the JD's are a spool design that fits inbetween the bull gears. We build hubs that fit behind the jam nut on the bull gears, then the spool sits over the top of the hubs and tension is contolled by a spring loader inside the spool which puts tension on the hubs. It does not fully lock the wheels together,,, it will slip long enough to make a turn, or use the brakes and then re enguage when the brakes are let off. Other brands, its all done with the brake pinion shafts, with an axle that goes clean thru, with the dry clutch mounted to the axle, or brake hubs. ChadS

Like I said before, Call Chad. Ask him about the limited slip differential. He will give you a big line of BS. He will NOT give you the names and phone # of three "of the top pullers in the leauges of antique puling" so you can ask them if it was worth the money.

Tell you what,,, read the Hook Magazine,,, results at some of the pulls,,, I promise you,, I know who they are, Identity is safe with us, at least till the HOOK comes out and lets us all see who won,,, we here, just sit back and smile, enjoy all the calls telling us how much it changed for the good. We are glad to have been a service, and a part of the pullers life to make that tractor pull better, farther, with what ever they drive. Even the Deeres!!! So, you take that for what you will,,, I dont care. But trust me,,, they got em, and they got em from thetractorshop.com ChadS

Lemmons also does a limited slip. It sounds good on paper but just isn't worth the money on the track. Ask Earl-Shad for some names and phone # of pullers running it and talk to them. Spend your money on a better set of tires. You're be happier.
