I work for Napa they have them the part# is 602-1653 they run $24 a piece.

 

I installed the transmission mounts this past Saturday and am fixing to go install (literally) the engine mounts (I was the one who bought his last set ).

Well . . ..

Comparing the: In good shape, stock/OEM transmission & engine mounts to these poly mounts, . . . . makes one appreciate the science that goes into a given mount, including "Mechanical Coupling and De-Coupling". Softer Rubber VS Firmer Polyurethane.

They certainly hold the engine firmer. This comes with a cost though, a firmer mount is gonna transmit more vibration to the frame. This means more engine related noise to the truck and the drum of a cab we ride in.


In my mess, anything below 800 engine RPM, lights up anything that is loose in or of the truck. Big-time rattle. Think of the high-school kid with dual, 1000 watt, 18" subs in the trunk bouncing a pocket-knife on the roof, laughing. Or so it seems inside my cab. Outside, it rattles like any other old diesel pick-up truck. Mostly the engine up front.

As the engine is sped-up, the engine vibrations smooth out and thus, everything calms down.


. . . It's gonna take some getting use too . . . . . .. . . .

 

haha thats how my truck was since it had one broken engine mount. i hope its not going to be as bad though with the new ones.

 

 

I must add that the new mounts slightly repositioned the engine compared to that removed . . . which should be expected. That may have contributed to the extra in-cab noise in my case.

Having drove the truck 30 or so miles including a couple of passes over some railroad track (perhaps a bit too fast) has things settle down. Considering I lifted the front of the engine almost four inches during the swap, I suppose things got a little tweaked.

It's much better now in gear, at idle (800 ~ 900 engine rpm) though it is noticeably louder than the rubber mounts. You know you've got tighter polyurethane mounts.

 

??? did it move the height up or down in the engine bay?

 

Not really. .. . . More like old, settled factory spec mounts VS new factory spec mounts.
