need some ERA rear info , snapped an axle again ...my fault again

[John Martin]

My Power lok works , can't upgrade parts inside .

I'm ordering MarkWilliams 30 spline axles , auburn LSD ,Centerforce dual friction kit w/pp,tob . I should be all set .

John,
Can you post some photos of the bits you are getting - before you install them?

[RICK LAKE]

john Martin. John you can break these parts too if we don't find out what is going on with the car or driver?? John I broke lockers good for 600HP in my Dana's. Going around turn and hammering it. Large soft tires. I think your car has wheel hop and until you change the rear suspension. 30 spline axles are not going to last much longer than 27 or 19. There is a guy on this forum with a 700+hp motor and ran 19 spline rearend in his car for years. I am buying the center section. This car also runs 18" tires for autocross, roadrace, and 1/4 mile. The other issue is if you are snapping the stubs now, adding a stronger holding clutch is going to make the problem worse. I hope you remove the sliding weights from the pressure plate, they cause shifting problems and lockup issues when the motor is over 3,000 rpms. Good luck John. Ps if you don't have a watt's linkage you may want to look into one. The other thing is to switch rubber mounts with heim joints and hard plastic. Rick L.

Sure , I will post picture of parts . Jag axles basically are great for a jag . But they can slowly twist over time . I did not think I was headed down the right road going after the old set up . I went with the Auburn Gear . I'll look into some sort of / upgrades to the rear suspension , thanks !

I chose to go back to a 331 from the 354 .

Rick Lake , I talked with the teck department at Summit .I mentioned about cutting the weights off the clutch . He said he never herd of that being done or an issue .He asked if I was side stepping it , no I said and intend on shifting in the hi rpm once in a while , he told me I would not have problems with this clutch shifting it hi up the rpm range . The weights add clamping pressure .
For you and one other person ( Doug ) both giving me a heads up on cutting the weights off , I would like to better learn and / or understand the idea behind it .Do you think you can shed some light here on you take ? Thanks !

[John Martin]

Will this increase the throw ?

[RICK LAKE]

John Martin. That clutch company is full of CRAP. They cost me a total of 6 grand to find out about the sliding weights and how they work. Even their own tech guys are STUPID. The weights load the diapham around 2,800 rpms and I couldn't shift my car. It did not depend on from what gear to what gear I was going. Under this rpm, no problem. Brought a second trans and still had the same problem. Short verse, the whole story is on an old thread. The Gold clutch is 30% stronger holding strength than a stock one and has a heavier duty hub to absorb drivetrain shock. You don't need the weights. I am still running the same pressure plate 14 years, but have installed a new disc a couple of years ago. I will goto a twin disc setup with new motor from Mcloed. ERA removes the weights on alot of there cars they assembly. IMO personally with 482 cubes the clutch is a little weak. IF you roll on and off the throttle I have no problem. Hammering the car, it slips a little. If you want to do burnt outs, buy a set of cheap hard tires for the back of the car. You can add a washer tank, hoses, and nozzles and make an instant water box any where you want. Having wet tires will also do alot less damage to the drivetrain when trying to start spinning the tires. Rick L.

The reason I have the Tilton was to move the clutch pedal back a bit (meaning towards the front of the car) to accomodate my long legs. I don't know whether it gives the slave any more travel (I suspect not).

Changed the trailing arms back to it's original state , caused tork steer under hard acceleration .Gear ratio is a nice change for the street !
