These look pretty strong and potentially a better design than the factory:

I just bought a pair of these http://shop.synergyo...m?productId=181


everyone on here says they work great and there 50 bucks cheaper.

those will not work on a zr2

[N2O_ZR2]

They are a nice piece, but I don't know if they bolt in. They look like they are quite a bit taller also.

From their website tech support:

Brian,
Yes, they will work. Thanks!

Do you have any information to back up that statement? They look right to me, no different than what I put in my Blazer....................Why wouldn't they?




Brian- They will work just fine, go ahead and buy them if you want. Especially since tech support gives the thumbs up, you can always blame them if not. Thats what I bought for mine and they work great. I don't notice the motor sitting any diff, it's in the exact same place it was.

[4wd Factory]

they work. the energy suspension ones are cool (we sell them too) but they are still the same design as the factory ones. im not a big fan of the factory design...

[cknaffle]

For most trucks, I would not recommend these. The extra cost and strength compared to the Energy Suspension mounts will give you no benefit, and will introduce a potential mode of failure to your transmission.

Those are nicely built pieces. If they were available a few years ago when I bought the Energy Suspension mounts, I would have bought them, only because my truck is highly modified and needs the strength this style of mount offers. But for a stock-ish truck, these are a complete waste of money over the cost of the Energy Suspension mounts. My Energy Suspension mounts have not failed or given me any trouble after 4+ years in there.

Poly bushing mounts typically transfer a lot more vibration than stock-style rubber mounts. That might bother some people too.

These style mounts are considered rigid because the poly flexes very little. If you make the motor mounts rigid and leave the transmission mount stock, you run a high risk of cracking your bellhousing or transmission adapter. Either all solid, or all flexible is preferred, not mix and match.

We are actually having this discussion in another thread right now.

I've been following both of these discussions closely. Would these mounts, paired with an Energy Suspension tranny mount, be desirable or would they not be a good enough "match" to prevent issues?

I'm looking down the road for the new toy... I'm assuming its mounts are all in good enough shape for now.

[CrashKnott]

yes.



maybe.

You're all set, engine and trans mounts are ES already. Same setup I ran with no functional problems or failures, but the trans mount did show signs of excessive deformation when I took it part. The best thing you could do to improve it further would be an anti-rotate mount on the tcase.

[cknaffle]

Something like this, but you'll need to grab several of the bolts on the case, since it isn't really designed to be loaded in this fashion.

I'll look into that once I've got the truck in my possession... thanks.

the zr2 frame is different that a normal 4x4 s-series. normal s-series have a 2 part motor mount system. the rubber mount that bolts to the block and a bolt on frame pad that bolts to the frame. In a zr2 application there is the rubber mount that bolts to the block and then the frame pad is an integral part of the frame. meaning it cannot be removed. meaning those mounts will NOT work on a zr2.

Ok, to each his own, but my grinder disagrees.

[cknaffle]

Wow, grinding off a motor mount is a damn lot of work when ES makes mounts that bolt right in.............

[N2O_ZR2]

they work. the energy suspension ones are cool (we sell them too) but they are still the same design as the factory ones. im not a big fan of the factory design...

The ES mounts have steel "hook" type things that lock the two pieces together inside the poly so they can't pull apart.

Either all solid, or all flexible is preferred, not mix and match.

Some transmission companies actually recommend poly trans mounts when using solid motor mounts. You need to have some give for chassis flex or you could split an aluminium trans case.

So did you actually put these on your blazer?

That brings up another good point that nobody has talked about yet in either thread - chassis flex. ZR2s are a lot better than some trucks that flex like noodles (old square body chevy fullsizes), but I'm sure it still flexes. I bet this was really a problem with the old muscles cars that had similar frame structure and often came off the line with one tire 6" in the air and the other on the ground.

A lot of that was in the rear suspension, the rear axle would want to twist and push the right side up into the wheel well. Now with sway bars and the traction bars that changes the instant center you can make them launch pretty good.

The do flex a little, I've fixed two little out dents on one of the quarter panels just to have them come back after one night at the track. I'm really worried on how bad the K20 is going to flex when I start playing with it.

lol, agreed. But we got a pair of these free when Baja was in "test phase" and got a store credit in exchange for time/labor/whatever. We were just jazzed to be working with someone like them. Install was easier than expected. The motor was out already and the torch did most of the work.

Sorry guys, I wasn't trying to be an ass or make an issue of it. Just tryin to say that with a little work, you can do a lot more than you think, if thats what you really want to do. (Chris-not that you of all people would need to be told that)
