Consider the alternative.
I knew I needed new motor mounts. I ignored it and focused on other things (mods).
My mounts let my engine move enough to where it contacted the radiator. This ended up having me need a new radiator, fan shroud, cooling fan, and fan clutch in addition to new motor mounts.
The $130 for the MORE mounts is nothing compared to what I ended up spending. I put the MORE's in.
Yeah your Autozone mounts are cheap and have a lifetime warranty, but is it worth your time to change them frequenty? Also if one goes out, and you kill the radiator, do they cover that in the warranty?
I would highly suggest the MORE mounts if you can at all scrape together the money. Do it once, do it right and you can save money in the long run... ASK me how I know this...
I went w/the cheap AZ ones about 1 year back and all seemed good. I recently (say 2 months back) replaced my OE leaking radiator w/a new 3-core unit. I thought all was well. When I excellerated even 1/2 throttle after installing the new radiator I noticed a TERRIBLE grinding sound. It took me a couple weeks of baby-throttling the XJ to find out that I had permanently scorred the 'new radiator w/the mechanical fan. Turns out, that even though my mounts still looked fine, they were allowing the engine to rotate and torque at least a good inch or better on just 1/2 throttle. So I replaced the AZ Mounts w/a good set f/MORE and that problem went away.
It took some work on my part because the engine had torqued and rotated enough that I had a 'job' on my hands getting the MORE mounts to fit, but once in, all is well (at least as far as that goes)... I can give FULL throttle and not problems at all.
Anyone's guess as to how much torque and wear those AZ Mounts were allowing to be put on my APN header, tranny mount, and everything else. Now I know my engine stays the way it should and doesn't torque/twist like crazy.
Ended up costing me an extra $40 for the AZ mounts since wen't the 'cheaper' way to begin with.

I have a question for those of you that have had the bad experiences with the "cheaper" mounts.Redsnake said:
What kind of "wheeling" had you done before your "cheaper" mounts went bad?
Some of us won't be putting our rigs thru the tougher abuse as some do.
Just curious .... as I'm looking to replace the "trio" of mounts in the next month or so.

My mount were bad when I bought my Jeep. 1 year later with not much street driving and only 4 wheeling trips (pretty mild, no rocks) i put it through the radiator.
The PO was a woman who never wheeled the Jeep, most it saw were dirt roads in Mexico and beach driving.
I think the MORE parts are worth it.

You all make some valid points. And i may have wasted my money on the cheaper motor mounts I will definitly go with MORE in the future. My other XJ needs mounts too just not as bad as the first. This will give me a nice comparison of the difference in the mounts. I will watch my cheap mounts closely and see how they act.
you can add me to the list of those who learned the hard way. 2 new radiators before I figured out the new NAPA mounts gave out after 2 mos. D'oh!B.RAIDER said:
I did moderate wheeling before. Doesn't really take much though if you're in low range to move that motor around.
I saved 130 bucks by buying cheap mounts. Then spent 390 on radiators and fan clutches later. plus the 130 for more mounts.
Unless your rig is a mall crawler, I highly recommend getting the more, or brown dog mounts.
Ok first to any of the "poly mounts" none of you will like those. Your rigs are uni body and with the stiffer poly they will transfer a lot........ and i mean a lot of vibes into your rig. when you are stopped its like a fat kid kicking the back of your seat. None like those except for trailer rigs.
Second I just dont get the "cheap" people out here. Your cheap AZ mounts dont just go bad, they just fail. And when they do, this is one of the reasons for the exhaust manifold to crack from stress on the manifold when engine moves..... then you come back crying about broken this and the shop down the road wanted 700 bucks to replace it and you want to do it yourself, then you tried it and it leaks, broke off a bolt or two, cant get this back on, the idle is irratic now. See the list goes on and on when you talk about the "motor mounts". One of the reasons I poste up the OMFG so expensive MORE motor mounts. Guess 100 bucks for clear tail lights is ok but motor mounts (actual part not just show) for 130 bucks is way too much..... should be more like 32cents and pocket lint??? Buy the AZ ones then come back here, post pics of broken mount, broken exhaust mani and tell us how you should have bought MORE mounts and saved yourself humility, 1000 bucks and time.

I run the daystar mounts in my 91. No problem at all with the install. The do transmit some vibes at idle, but only at idle. Nothing annoying just something noticeable. I would recommend them without hesitation. They are now 4 years old and look as good as the day I put them in.

Due to budget constraints I will have to stick with what my local parts houses have for mounts....

It is very simple, like with everything else in life, you allocate resources according to priorities. A Jeep can be fun to play with but, for many people not at the top of the priorities list.
Priorities such as a new roof for the house or buying books for a college kid may be higher.
I hear and understand people when they simply don't have the cash to do it w/better quality stuff... ie... MORE/Daystar vs. Autozone/Napa Motor Mounts... but I can ONLY speak f/ my personal experience and say that when, not if, but WHEN the cheaper mounts wear out or break, it will cost you a lot more money to replace things such as cracked headers and busted radiators.
Oh... and to answer a previous posters questions. My XJ is pretty much my Daily Driver. Does little to no offroading. The occasional trip thru my yard and up/down a ditch, but that's about it. On occasion have slowly jumped over a curb or two in a parking lot, etc... but that's it. No rock climbing or hard-core off-roading. Just the normal torquing of your engine f/giving it gas stresses the mounts and if they're of sub-par quality you will eventually break them.
Priorities are just that. Me, I'm 38 yrs old, have a wife and 3 kids... as an example, my priorities would be to put a 200 dollar alarm on my XJ and my 18 yr old son's priorities were to put a 200 sub and amp in his older XJ first before the alarm (against my suggestions)... guess which one got broke into and had the subs stolen? We live and learn. It's your money and your XJ... but you asked for our opinions and you can learn f/us, or learn f/your own experiences.
Let us know how it turns out.

The MORE rubber mounts are worth every penny. I too had to replace a radiator and fan clutch when the stock mounts gave out, the MORE mounts are worry-free. I've never heard of anyone breaking one. On my '91, the passenger side was the bitch, had to remove the oil filter mount housing to get the bolt out. On the whole it's not a bad job, a couple of hours and you're good to go.

WHoa!!! Gentlemen, CALM the (naughty filter) DOWN!!! I didn't mean to start a war here!!! All opinions are welcome, but PLEASE don't bash each other!!
I can see the value in certain mounts over others, and in due time, I will install them, but for now I don't have any extra income, seeming a I am unemployed and the wife is the only one with a job at the moment.
