Default Stiffer engine mounts?

Does anyone make a poly engine mount for our trucks? I just dropped a 6.0 LQ4 in my Yukon XL, along with new Anchor Engine mounts and transmission mount. The engine is moving on the engine mounts enough that it's causing the long tubes to smack the frame on the drivers side near the front diff yolk. It only happens from a stop when you put your foot on the gas, or when suddenly applying the brakes firmly, it taps the frame. I'm thinking this might be an issue with the new motor mounts I put in being crappy quality rubber.

Is there anyone that makes a polyurethane mount? Energy Suspension and prothane do not have a listing for the NBS trucks.

I see a fresh rub down there between the header and the frame. I'm also replacing my ball joints and front left/right/upper/lower control arms and bushings with the Raybestos Professional control arms, and Energy suspension bushings. z71 Bump stops are also going in. I'm also upgrading my XL torsion bars to GF Code bars off a lower mileage truck. The truck just passed 170k, the front suspension is sagging a bit and I tow about 8klb travel trailer once-twice a month so I figure it's time to get alot of this maintenance out of the way.

Poly mounts are not made at this time for these Vehicles.

I Don't believe the aftermarket replacement mounts have the same quality rubber as the OEM mounts. I have seen them wear out much faster than an OEM mounts.

Yea I would just find some newish OEM ones. I doubt there are any poly aftermarket ones because the mount is a captured design.
