I have a small amount of money to put into my jeep and I want to put new motor mounts and tranny mount. I was looking into the brown dog polly mounts and possibly the engin brackts but I need my motor to stay in the stock position. Any one have these and know if the motor was moved at all after they were put in?
also whats a good tranny mount?

My son just put in the BD mounts.These thing are made well and in the US.We just orded a set for my XJ also.He just used a OEM trans mount .

Brown Dog stock-height motor mounts put your engine exactly where new Jeep motor mounts would put it. If your current OE-Style motor mounts are worn, your engine is no longer in its original-when-new position, but is 'sagging' due to the worn rubber. The Brown Dog mounts return it to the original position. Not a 1/16" higher. Not a 1/16" lower. Thank you for asking.

We appreciate the kind words. Thank you.

My other question is if I buy just the motor mounts can I get the engine brackets later or will I need the kit? I ask because the application notes say that the mounts are for use with the stock engine brackets, only. I want to get the super brackets but I can only afford the motor mounts right now.

What's the difference in you classic and ultra flex motor mounts? Wasn't even thinking of new motor mounts till I read this thread....and the qaulity of your motor mounts. Just need to decide classic or ultra flex. My XJ is stock for now...small lift very soon. But no more then 3 inch. No engine mods yet....just 703 injectors. Whats the difference in the two you offer and which would you recommend me buying?

So I called the tech support and got the low down on the motor mounts. You can buy just the motor mounts and they will fit with the super brackets you buy later on. However, if you buy the kit, the motor mounts that come with that kit are designed to go with the super brackets and the ride quality is better. You can get the motor mounts and later get the super brackets but the ride quality is better if you buy the kit.

kyledye25, this should tell you what you need to know but basicly the ultra flex have les engin vibes.

Brown Dog also has awesome customer service as well. They've definitely earned their reputation for quality products and a customer-first attitude.

Save yourself some trouble and just get some replacement OEM mounts. They don't go bad that often. With the aftermarket mounts, going with solid mounts or poly mounts, you'll get more engine "vibration" through the interior. You'll feel it more. You want more of a rubber mount to take the vibration. The OEM mounts were made for the 4.0 so I don't see why putting in King Kong mounts are necessary. If you changed the motor for high torque or something then I could see.

Lyon, if every xj was stock then I could see your point. We modify our jeeps so that every part is stronger and better, breaking a motor mount is not unlikely. once you break a mount you will want better ones and it will always haunt you when wheeling. I want king kong mounts because I don't think stock mounts were ment for wheeling. I also have broken motor mounts on every truck or car I have ever owned regardles of going offroad or not.

Are you serious? What brand of stock mounts are you using? Are you talking about dealership mounts? Are you sure you are checking your mounts properly? Look at them ... if the rubber is torn, they've gone bad. If the rubber is sagging, and there is daylight between the rubber and metal housing, they've gone bad.

Mine go bad about once every year ... I'm sick of replacing them. The rubber flattens out over time (causing the motor to sag about an inch) and the rubber even gets torn in two. Your avatar picture looks like you do a lot of rock crawling, which probably doesn't pound the mounts as much as fast driving on logging tracks and desert washboard. I drive closer to a pre-runner style, which might be harder on the mounts than crawling.

About the harshness ... you don't have to get solid or poly bushings. As noted above, BD makes rubber bushings that are almost the same feel as stock. Also, MORE and Rusty's make mounts that use stock rubber LCA bushings, which are even closer to OEM feel. And they are completely bombproof.

I'm going to try to make some DIY mounts based on LCA rubber bushings. I've started a new thread about that here:

If you've broken mounts on every car you've owned then you obviously ride your vehicles hard. I understand you wanting stronger mounts for the sake of torque purposes but the power should be transfered at the transfer case. If anything, I would think you'd wear out the trans mount 1st. No?

Lyon

I've had my Jeep for 2 years and still using the OEM mounts on it. Yes, I do rock crawl, and also do mud and water as well. I just don't drive it like a maniac when I do it. Yes, I've checked my mounts properly. I haven't had any issues to even check them but I do as part of normal routine maintenance.
For desert running and racing, then you obvioulsy have more upgrades in the speed department and like I said, if you're going for torque and high performance then by all means go with the upgraded ones.

I follow every trafic law but I cant avoid every pot hole and every bump in the road. Bath tub size holes in the street are not uncommon where Im from(oakland but living in carson city) and the last truck I had was babied everywhere I went(put two sets of oem motor mounts on it due to a cracked frame on both sides). If you have never had motor mounts go bad on you then you either drive with broken mounts and not know it or you drive like miss daisy on a flat unbroken road. Im sorry but there is no way you can drive in california without breaking or wearing out something.

Lyon

I commend you for respecting the law with safe driving habits. As we all should and probably do. I will say that I am not a real aggressive driver but I'm not a miss Daisy by any means. I drive safe and respectable to others on the road. I also take caution when I'm 4 wheeling as well. I'm not one who goes out and says "if you didn't break anything you didn't wheel hard enough" I'm the one who wants to have fun while on the trails or wherever we go and know I don't have to be under it fixing something just to get me home. It's not a trail only rig.

Most of my cars I've recently owned have been new, mostly highway driving so the need for motor mounts were never an issue. In the years I worked as a mechanic, I did change lots of motor mounts on many cars. I'm not saying they never go, I'm saying they don't normally go that often in the same vehicle. Basically, what I'm saying is, if you change the mounts you shouldn't need them for atleast a few years. Not once a year. And I don't recall potholes or cracked frames causing motor mount failures either. Just saying.
