5.7 Solid Motor Mounts

[What?]

I'm only seeing conversion from LS/and other motor but not only just only for 5.7

What are you hoping to accomplish?

I can't think of any application where solid mounts would actually be an improvement over the OEM clamshells.

Too bad there aren't any OEM clamshells available any more. They were wonderful.

The aftermarket clamshells are flimsy garbage.

 

[What?]

Buying a set already built instead of making one.

Offroad Design's make a solid set. I have some, just haven't put them in yet. Made extremely well with polyurethane bushings.

How can they be "solid" if they have Poly bushings?


I tried to put Energy Suspension Poly inserts into my OEM clamshells a couple of years ago. The ES inserts weren't even close to the OEM rubber inserts for shape and size.

Photos 1 and 2. ES Polyurethane mount insert compared to OEM rubber insert.

Ok, well I suppose they would "give" slightly but these are a different design from the original ones on our trucks.

Clever, but clearly NOT "solid" mounts.

Whether they're an "improvement" or merely "different and profitable" is something I'm not able to discern. As a wild guess, I'd say they're better/stronger than the common <$20 aftermarket clamshells, but then the aftermarket clamshells are a complete disaster--very thin stamped-steel and a rubber insert of questionable quality.

The big question is whether they're stronger than the OEM clamshells, which were made out of much thicker steel. The OEM rubber insert does get beat-up over time. It's a shame that ES doesn't make a proper Poly insert that fits like the original.

Are you talking about the frame side mount? 15529450 $44.42 in stock at my contracted dealer.

Yeah, "solid" seems like a bad idea. Maybe that's not the right word?

So there's a stamped steel frame mount (clamshell?) That goes over the frame mounting ears or something like that, right?

Then there's a mount that goes between that end the engine (engine mount?) The engine mount has some sort of material that absorbs/isolates vibration from the engine and road bumps, etc. Also allows for a bit of engine rotation when you need to unbolt transmission bell housing bolts for removal.
