I know on the import side select models have them. Intense racing sells them. Are those better than the Phantom Grip?

I know I was looking into this for quite some time..but really i did my homework. A set of springs with two plates will not do the trick.

It works under regular load but i can promise that without a true preloaded limited slip you will encounter wheel spin that is uneven and it is this slipping that causes the breakpoints.

I would have been selling phantom units a longtime ago if they worked as a true limited slip should.. They are good for what they are but on a car like heavy gm they are NOT as good or as reliable as a truly preloaded limited slip.

The test that is best is to place one wheel in the wet and the other on the dry. Now without staging hit the gas full and hard and watch a phantom slip and partially grab. With a true preloaded unit it will spin both wheels equally without issue. I will provide a video when soon as i can.. This is the same issue that is found with "other" Limited slips that were not built with true clutch material and properly balanced springs.


All that said its not bad. its just not a serios unit and is a partial solution.. that is why it is cheaper.

Look in any 4X4 mag and phantom is not found.

Under serious load it is no good. The limited slip with a true preloaded system is truly the best medium solution. the best is a Torson unit but cost is in the thousands.

So how good is the Intense Racing liimited slip then. I know about Phantom grip not always locking both the wheels everytime.

What about the upgrade kit they provide. Or does it not apply to your years. I jhust saw they came out with the INTENSE™ 4T65E-HD Transaxle. Comes with alot of things for the price. Jus tcurious to know how much power is it cpable of withholding.

well for the power they will hold, i think that intense has the fastest GTP and the fast bonneville in the country. GTP- 10.80, bonneville- 11.60
my car has a 4t60e hd they have to custom do it

I just emailed Scot to see how much additional it would cost since I dont have the 4T65E-HD. Hopefully the price wont be to be bad. This way I can start calculating how much money I need and in what direction am I going to be going in.

Intense and phantom are equal in performance just different styles of reaching the same goal.

Both are incomplete.

If you want a true final solution you need more than springs and plates.. you need more than resurfaced metal thrust washers.

There is a need for actual clutch material.. much like the transmissions we use there is a need for more than metal plates used by intense and more than springs provided by Phantom.

So if you can get the clutch material and get properly calibrated springs and mounting systems then you will have a actual preloaded limited slip. I have spent many hours working with some great builders and yes talked with some of the team who made the eco monster 4t65-e. I don’t spend my time trying to reinvent the wheel. It has been done and all my time was spent finding a experienced builder and full solution.

As usual it costs more for all the time and calibration but for a "true" preloaded limited slip (posi) you need more than part of the mix.


That said most people on this board probably care less and a phantom is cheap and yes it functions "like" a limited slip.

With this unit you will notice the springs not available with intense and the thing you cant see is the clutch material that intense and phantom do not offer.

Sorry I have done my homework and this product is not bettered within its type anywhere. You can improve on it with a Torson but the cost is substantially higher.

It is still being improved for extreme hp use but that is also soon to be finished.
