Raised mine about an inch, but my mounts were squished and deflated stockers, so...

 

This would be inconclusive because most people who replace their motor mounts are replacing broken/sagging/worn out stock mounts. If you compare new stockers to our mounts then the engine sits in the same spot. If you are comparing destroyed/sagging stockers to our mounts then, of course, our mounts would raise the engine back to the proper position.

 

The reason I called this into question is the specific vehicle that we installed them on required spacers between the cradle/frame and a relief to be cut on the underside of the of the hood to clear the motor/driver for the throttle body after installation of your mounts...this was on an 07' LS2 with a Magnuson supercharger.

I have never heard of this being required before, and I have no other frame of reference, which is why I raised the issue. Regardless, the owner seems happy with your product.

 

I think the explanation is simple: while unloaded Revshift and Creative Steel motor mounts may be the same length as unloaded OEM mounts, their higher durometer material doesn't compress as much under the weight of the motor. I speculate that neither company took loaded motor mount length into account during their design process.

 

We did take it into account. The loaded measurement of the oem mount is 1/16 of an inch shorter than unloaded. Not enough to make a noticeable difference.

Also, why are you only comparing us to CS? Why not UMI or UUC? If you are going to question one then you should question all.

 

Well I ended up getting my motor mounts installed last night and as all others have stated, what a difference it makes. Clean and quiet start ups and shut downs, less vibrations than the busted stockers and just an overall awesome product. Bravo Revshift, bravo.

I was able to get the passenger side installed without removing anything at all, including the wheel and Pacesetter headers, which only took about an hour.

The driver side was the issue for me due to having Pacesetter longtubes that are welded at the collector, which was something I didn't want to have to chop up. I ended up being able to remove the stock mount with out removing anything other than the steering linkage and unbolting the headers from the heads which gave me enough wiggle room to get the two bolts that sit right behind the runners with some long extensions and a swivel socket. Took me about 2 hours start to finish on the driver side, which wasn't bad considering the tiny and cramped conditions. It was definitely a jigsaw puzzle trying to get the OEM mounts out.

 

AFAIK, UUC is not an active vendor of motor mounts for the first gen CTS-V. UMI's design is fundamentally different than Revshift or Creative Steel. Before I submitted that post, I had a couple of sentences specifically addressing UMI's design but deleted it because I felt it was excessive.

 

This should be interesting. Installing mine today

 

i hope it went well the lost driver I will be doing mine in a couple weeks

 

Still waiting for mine...haven't herd a drop from Revshift about when they are shipping them (as well as trans mount and Diff bushing). Ordered them 5 days ago and figure it can't possibly take that long to package and ship the above items. Its awesome hearing all the great feedback from everyone who has them, and its kinda of bumming @ the same time as it seems like I wont be seeing them until well after the new year...

 

Yea dude, it'll probably be awhile, I ordered MM's, cradle bushings and a rear dif bushing right when the Black Friday sale went off and I still don't have my stuff. I just ordered a trans mount last week and it came in today. Kinda sucks because I had plans set up for about a month now and it looks like I won't be doing anything.

 

I have rev shift blue motor mounts and although my factory mounts were bad, the feel is amazing. I feel like I went from a cammed car to a civic. Highly recommend.

 

Oh my it was a PITA! Wish I would've installed these things when I did my headers lol. I ended up changing my oil and removing my starter for clearance to remove the old motor mounts but after I finished installing it..... What a world of a difference. I have the red ones and vibration is pretty minimal. Much less that I expected from a more firmer mount. There is vibration there but the amount does not bother me personally

 

see difference in stocker with 40k on the left, and brand new on the right.

 

I might need to replace mine.
