LS swap frame side engine mounts

I need new engine mounts since I had to swap frames for the 07.

My swap was an RPMExtreme kit using Jon's frame side engine mounts which use the GM engine isolators.
His mounts are $299 + $31 to ship


I've PM'd Motech and JohnP to figure out who I'd get the frame mounts from now; waiting on replies.
Neither website is easy to figure out a price/availability. Also not sure if they can use the GM engine mount, or what exactly I'd have to change to use theirs.
ETA: JohnP said they have an engine mount using the JK frame side mount.


Novak makes an GEN III/IV LS engine mount that is frame side and engine isolator as one package.
Novaks price is $212 + ?? shipping.


JSS... unclear what the fuck I'm looking at since I have to watch a video to see the product. I'm guessing its the engine side mount, that bolts to the factory JK frame side mount? Who knows though, no description on the site, and no technical details in the video.



Anyone else know any other options?

I talked with JohnP. Waiting for availability and pricing for engine side mounts and keep the JK frame mount.
Robbi said he'd assist if John doesn't have any available yet.


Novac is in the running then if I end up having to cut the frame mounts off.

I stumbled upon these by accident, drop in brackets with no cutting/welding.

I wouldn't use them personally as the price is ridiculous, I'd just make some with a kit from Ruffstuff or something but for a quick drop in option this should work.

2008 JKU Sahara on jack stands with suspension completely removed, engine completely exposed, crossmembers cut out, and wiring harness dangling by the firewall. Soon, IFS front suspension with trailing arm 4 link in the rear.

Yah I saw theirs and laughed at the price for what they give you.

I'd make my own but the problem is making sure the 5.3 is located in the right spot. Shits tight between frame rails and firewall clearance. I'd rather pay a couple hundred for the piece of mind someone else already figured it out.

Best bet for lowest headache factor would be exact match replacement RPMExtreme. Besides, they seem like a reputable business, good customer service...

Swear if I ever have to replace the frame, I'd rather make a whole frame from scratch than deal with my kit's vendor...

I agree. But for the work involved the Novaks would save me $~100.

Or engine-side mounts using the JK frame side mount would be the simplest.


FWIW, I did PM RPMExtreme asking some questions. He got on that night or the next day and no PM has been returned... he had been easier to get a hold of by phone though.

I haven't been getting on JKO all the much lately and for some reason my notifications were off. Email or phone is always the best.

Are frame mounts work with a Hemi, LS and we use the Grand Cherokee isolators that are in our BOM page.
