Solid Motor Mounts - Good or Bad?

Lew Silverman · 03-24-2011, 10:04 PM

Has anyone had any bad experiences with solid motor mounts? I had heard that they could deform the cylinder block. Would the poly mounts with a torque brace be more efficient? Should a solid tranny mount be used with the solid side mounts?

Thanks!

A couple folks that I know personally have cracked their automatic transmission housings using a solid transmission mount.
Most use solid engine/frame mounts that I know of.

Solid motor mounts, a torque restraint, and a polyurethane transmission mount, is the ideal setup, if you're not allowed motorplates. And even with motor plates, front and mid, I use a polyurethane transmission mount, never a solid.

Used solid mounts and a rubber trans mount for the better part of the 17 years and over 4000 passes I made with this nearly 2 ton ride, without issue. I would never used a solid trans mount.

Just wondering, why do they even make a solid tranny mount? I don't know anyone the uses one and everyone will tell you to never use one unless you enjoy broken cases.

Circle track guys use them. And people you can't tell anything will try them, then wonder why they're having problems.

Full Chassis cars with 2x3 frames rails. Both of our cars had solid trans mounts and never busted or cracked anything.
