Im a machinist, and I was wondering if anyone out there has a TJ 2" coil spring spacer lift lying around that they could measure and make me a drawing of its diminsions.

I have a stash of aluminum and UHMW plastic that I could make my own, but Im not sure what they look like exactally, and Im not gonna pay 300 bucks for a plastic spacer that I can make in on hour out of billet aluminum

Buy one copy it & send it back.
 
hahah those are some interesting ideas...

aluminum is very expensive in billet mechanical tubing.. the piece that I procured from work is a leftover piece from a job, and its only enough to make about 3 maby.

but I have a bunch of that UHMW stuff, in 2" sheets.. I can bandsaw the OD and machinie it to size in the lathe..

but as far as the aluminum.. I cant make much of that.. I was hoping to cheat, and make (2) 2.75" spacers... and all that will be left over is a piece small enough to chuck on.


oops, nevermind... I just realized... duh I need 4 of those spacers to lift the jeep.... for some weird reason I forgot about the back springs..

in that case.. it would be cheaper to just buy that daggone things... beings that skyjacker sells them for like 120
I will likely just do that instead of making them, for now... I might still experiment on making a 2.75" spacer out of that UHMW plastic.. to gain some extra lift..

thanks Joe
 
I may be missing something but you can get poly lift spacers for dirt cheap on ebay.

http://cgi.ebay.com/ebaymotors/Jeep...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

Those are going for just over $30 a pair shipped... That'd lift a TJ 2" for around $60

I've had a set (not this manufacturer but some other ebay outfit) for around 3 years and they haven't really collapsed or worn strange or anything...

To be honest, I bought a 3" kit back when that came with 2" spacers to go under 1" spacers...Not the best setup but it worked until I decided to get coils, then it was nice to have the 1" spacers around, I ended up using them on top of the lift coils I bought to level things up.
 
You've officially made a coil spring spacer much more complicated than it really is. And as was said, for the price it's almost not worth your time.
But, 2.25" id, 2" spacer height, 4.30 OD, flat side is .80 from the inner wall, the rest isn't necessary, but they usually add a recess at the top for the original isolator to fit into and a lip on the bottom that's the same as the OG isolator's to center the spring.
If you make it out of aluminum, you might have to change some things up such as the ID. Why not just measure your heep's stock isolator and add 2".
 
ok I know it is making it all complicated... but things are slow at work and I can make these for free... that means I have all that money I could use on tires instead of 4 pieces of plastic..

I found a 5" OD stick of UHMW about 4 foot long that would work perfect.

what I need to know is...

whats the angle on the isolator, and whats the large ID on that angle?

what angle? I am pretty sure everything is square. I have a set od 2" spacers at home. the only thing that looks remotelly 'high tech' is a small `1" flat cut on the OD. I seem to recall the flat was for some kind of Grand Cherokee, maybe a TJ. My 1" spacers have no flat.
 
Maybe the angle your referring to is the angle in the "lip''

Besides that its straight. I would make the inner dia a tad bit larger than these if your making them out of something less flexible, It can be a tight fit. Like Brax said its a 2.25 inner dia straight
 
ok, from those two right there... whats on the other side of them if you flip them over... isnt there a taper in the hole so it locks in on the isolator on the jeep.. or is it perfectly square and flat with no features on the other side.... all the pics Ive seen dont show the other side, so I dont know whats on there... but looking at it carefully, it looks like there might be a tapered hole?

The spacers pictured above will stack on each other, so yes, there is a 'countersink' you can't see in the picture, it is inverse of the raised portion you can see.

Your time must be awfully cheap, you could have ordered them and had them installed by now...

Really though, I think you're making this way harder than it has to be. I understand if you want to make your own, but they're not that complex and you have all of the parts in front of you to take measurements from if you have a TJ to install the spacers on.
 
Ive ordered the cheap ones off of ebay, and when they get here Im gonna measure them and possibly make some that are 2.750 long instead of just 2 inches..
I know this is gonna make my springs tight as hell, but its just an experiment..

plus I havent gotten the rims yet, not till next week, so Im not really in a hurry to get the lift on yet... its all good
