I don't know but I starting to think that this might be close.

I need to rescue my car. Sad

Detroit locker

But what are you going to put it in

chevymad · Posted: Wed Nov 09, 2011 6:48 pm Post subject:

It's tiny.. fits in one hand..

And yes its a locker. But its a Lockright for my 74. This goes into the open carrier and replaces the side and spider gears. Basically a ratchet.

Neat, I found one or two of those when I was searching for the Eaton I ended up with. Couldn't use one though, the carrier I had was already a posi. Might have worked for the V6 though.

This ones for a 28 spline 8.5" 10 bolt. Sure seems tiny.. fits in one hand.

Ran out of work at work... so I brought the 74 in and installed the locker today! Very Happy

Super easy. Thing works slick. It is noisey though.. if you roll one wheel forward, then push the other one forward it locks up solid, but if you roll them in opposite directions it ratchets.. clunk clunk clunk.. You hear it every time you turn a corner. Unless there's some pressure on the driveline.. then you feel it lock up and the back end start to lift..

Starting to install the drivers..

Here's the other half of the ratchet mechanism.

All installed, clearance is right at the minimum. Perfect!

Is the noise worth dealing with?

QwkTrip · Posted: Fri Nov 11, 2011 5:54 am Post subject:

I had one of those (different brand) in my '68 El Camino. It definitely works in the straight lines. Not noisy, just a mild clicking sound. Makes for an odd handling car in corners since it switches the drive wheel to opposite side as normal. And every now and then there would be a massive *CLUNK!!!* from it, usually around 50 - 60 mph. It was as if it got all bound up and the clunk was finally the release of stress.

chevymad · Posted: Fri Nov 11, 2011 7:32 am Post subject:

They go so far as to tell you to inflate tires using the circumference method. Probably to prevent that massive clunk. I've only got about 15 miles on it now so no real experience yet. I did notice on a downhill corner, as soon as the driveline started to take pressure, the clicking stopped and wheels locked together. The rear of my car starts to sort of lift when it locks in a corner, at least when the tires have traction. I can see this would not be a good thing on ice. And will just have to find out how it works the rest of the time.

blue89 · Posted: Fri Nov 11, 2011 7:43 am Post subject:

Can you explain how it operates? You make it sound like its an open diff until both wheels move forward. Wont that make launches unpredictable if you have one tire slip?

chevymad · Posted: Fri Nov 11, 2011 5:33 pm Post subject:

It only releases a wheel that moves in the opposite direction. If I push forward on a tire with the trans in park.. that wheel will lock and the tire will stop solid..Now I can push forward on the oppposite wheel and it too will be locked. But if I push rearward on the opposite tire, then it ratchets.

Works the same either direction either wheel. So on a drag strip, neither wheel will be trying to back up so both will be locked solid to the driveshaft.

It's kind of hard to get your head around. And I'm not positive on how it really works with so few parts. You'd think the teeth would be ramped or something directional, but they arent.

I do feel it lock and push when I power on in a corner, you feel the same thing in the opposite direction when slowing down in a corner. Don't feel a thing straight on. I really dont think this is what a guy would want in a cornering car, but I hear positive things about them at the drag strip.

From Richmond

Designed to send the engine power to the wheels with the most traction, the LOCK-RIGHT will help get you where you want to go. While traveling straight the LOCK-RIGHT will lock the axles together similar to a spool. However, when the wheels need to differentiate in a turn, the LOCK-RIGHT will allow the outside wheel to rotate faster to complete the turn. The internal gears on the LOCK-RIGHT will overrun each other to allow this differentiation.

This is their old school design. They have a newer design now that doesnt make noise and is recommended for muscle cars. They recommend mine more for offroad now, though serious drag racers still like them better from what i've read.

Here's their detail page and explanation of how it works.

Oh, it definitely works from a stop light. Very Happy

And it adds a little strength to the differential by replacing weaker components. I did drive mine in snow a few times. You have to drive carefully. Better off just leaving the car at home if the roads are slick.

Definitely not for corning. It does the opposite of what is needed for vehicle stability. When you have traction in the corner the inside wheel is driving which pushes out the rear of the car. If the car slips then the outside wheel gets traction which can snap the car back the other way. I never had anything like this happen but I was aware of the risk and drove corners easy.... and then hammered it in every straight. Laughing

So what happens when you are sideways at 50 roasting both tires? Do they both stay locked or do they lock and unlock? What happens when you sliding sideways with no power and then mash on it?

chevymad · Posted: Fri Nov 11, 2011 7:14 pm Post subject:

Roasting the tires .. they're locked solid. Sliding and then hitting the throttle will cause some wierd shizzle to happen.. during the slide you won't know which wheel is locked or if both are, then when you hit the throttle the one with the most grip or the one thats going the slowest is going to power on.
