Polyurethane VS. Forged aluminum BB lift spacers?

I've been pricing different budget boost kits, including ebay ones, and for the first time that I've ever seen, they have a Forged aircraft T6061 aluminum Spacers for the F&R for $100+ship. Has any one ever used these before, and what would be the advantages/disadvantages? For the price, if they're good, I'll pick up a set & shocks, but I know nothing about these... What do you guys think?

They should be fine if you want to pay the extra cash for aluminum. There ARE adjustable aluminum spacers out there and I've seen some homemade steel spacers used. I just went the poly spacers since they're cheap and won't be on my Jeep too long.

With poly it may cut down on vibrations a little bit.

ive heard of bad things happening with metal spacers. the general rule as far as i can tell is to stick with poly with the exception of ACOS which are the adjustable metal ones.

I was thinking poly may also be quieter. If you decide to use the metal ones make sure to reuse/replace the spring isolators (rubber disks between the springs and the body)

hmm...I think maybe i should just stick with the poly spacers. I also did some research and found that some people have had bad luck with the alum. spacers. Could anybody recommend me a good brand or site they've used and have had good luck with? I looked at Kevins, but for only 2.25", theyre pretty expensive. I want to get the spacers, bump stop extensions, and extended shocks, all for a reasonable price, around $250 in total or so... Thanks

A poly spacer is a poly spacer. Find the cheapest one (besides the "slip in" ones that are split) and buy it. You can usually find used ones for dirt cheap too.

fat bobs garage (to whom i have no affiliation) has the cheapest ones that i could find on ebay that seemed like they would be any good, they have a lifetime warranty, free shipping, and 100% positive feed back

I think I'm just going to go with IRO. $60 for the 2" spacers, $140 for extended-length Hydro Shocks, and $10.90 to ship it all, for a total of $210.88. I think this is my best bet, since IRO is well-known, and I'm sure many people have ran this setup. Good enough for me. Also, I was looking at the spidertrax wheel spacers IRO sells for $99, with the stock 245/15 tires, will this cause any sort of rubbing or issues, because all i want is the wider stance, not problems. Thanks

On second thought, that Fat Bobs Garage set-up doesn't look like a bad idea. IRO doesn't offer anything but a 30-day return option, and FBG has free shipping. Plus theres a set of rough country (i believe shocks) on there pretty cheap too, maybe I'll grab those to go with it.

I got mine from fat bobs garage. I dont remember the price i paid but i do remember it was cheaper than iro. Also the kit from fat bob is 2'' exactly but the iro kit is only 1.75'' i called both companies to confirm the size first. I went with the hydro 1000's but im not to fond with the ride quality. IMO i would have went with black diamond shocks knowing what i do now.

I've been running the same aluminum spacers in 2 trucks since about 1995. No problems, and the old XJ was shut down with over 450,000kms on it. These are billet spacers, machined for a friend and then sold to me when he went to even bigger spacers.

Apparently, some poly spacers (Daystars???) are to be avoided as they have a split in them, which allows easier installation (you don't pull the spring all the way off). The split might allow them to come off under severe loan (ie jumping). Also, some have complained of poly spacers settling/squishing.
