OMG somebody actually going to make these :eek: Like every one else I want to see a pic of it and the bolts and how much :cool:
 
I AM IN since im going to be getting a obx
 
then all we need is a custom diff cover made with thicker metal and a rear bobble strut mount !

I will buy 3 OBX this year, need one spacer though for the Rampage. They should sell well as the OBX is cheap. If all a person could buy were the expensive Qs there wouldn't be as big of a market.

other than price, same question as everyone else, what about weight? How much rotating weight do these add? Can they be done in aluminum? Not in the engine I don't know if expansion is an issue in a trany diff.

Can they be done in aluminum?


My Machinist swears i can make these out of aluminum. (He says the only thing the spacer is doing is locating the diff n the gear. The bolts are taking all the stress) I "PUNKED OUT" Make it out of steel please. I said:eek:

I'd hate to have the bearing clearances change when the diff gets warm and the aluminum expands.. or on a cold winter morning when it contracts..
Wow you really know allot about engineering, I am really amazed. So tell us how bearing clearance is going to change when THERE IS NO ALUMINUM BETWEEN THE BEARINGS? LMAO. Do you even know where the spacer goes or do you have no idea what a diff even looks like? Even the ring to pinion doesn't change during expansion and contraction. Really? Yeah as the pinion and ring run parallel. The only thing that can happen is that the ring ride centerline could change. But on a FWD ring it almost doesn't matter, I say almost because it can move 1/16" in either direction no problem. And the ring moves and must be able to move side to side some because of the bearing presets and shims. On a RWD the pinion is 90 degrees off of the ring and where the gears ride must be right on, depth and distance. There are 2 problems that can happen with aluminum spacers which is flex under torque, which can do what...... Cause the pinion and ring to spread taking off teeth. But given the thickness and given mass of aluminum should be more than enough. Problem 2, expansion and contraction under heat stress can cause the bolts to come loose. In the end like aluminum rods the ring would be fine on a race car and cause a problem in a daily driver in time. And the expansion and contraction isn't that bad going from 40 degrees to 200 degrees. A piston goes from 40 degrees to over 1,000 degrees, WAY different.

the other method could be to double the holes, to reduce weight. But there goes cost again

"I should have said one now more later
Price????."

I only want to cover my costs. I need a spacer for my 413, no one makes one. I might as well make them. i have all the equipment to do it . Alls i want to do is come to the shop turn the mill on and make 3 0r 4 during the course of the day .

The cost (overhead) Zero i am here any way
(material) price for metal. bits
(initial payment for program)

How many can i realistic sell?
 
I'd definately buy one, at only 14 psi my 2.5 puts out waay too much torque for my tires and to even begin to think of launching with any kind of boost off the line! Plus I like burnouts, and I don't know how much longer I can wisely refrain and save my 413's diff!
 
i would buy one from you if you actually had them ready i am getting ready to do a obx install and would like to have the spacers for them

I'd imagine you could sell 10 without blinking an eye unless the price is insane.. Keep the price around $50 or so, and yeah, I think 10 of them would fly out the door as fast as you could post your paypal address.
Why not just give it to you:confused: My spacer will be finished next week I will post some pics when mounted to the obx.Just for reference the 12 longer socket head cap screws 12.9 grade which is the only thing you should use cost 55.00.
