Which way would the frame or frame sections flex or twist across a horizontal plane if I were to remove this "crossmember" on a 2x4 truck.?

Would one side raise higher than other when going around a sharp corner.?

again, the engine is not stiffening the frame. if it is, you will be seeing a cracked block soon. talking about this crossmember is drawing away from what i am talking about with the engine mounts and block stiffening a frame like you have said.

Try it and let us know the results, I don't see you doing any road racing here anytime soon to prove this theory of how the motor mounts make the frame stronger lol

Prior to and now the difference you can feel when I back the truck out of the driveway off the sidewalk/rolled curb onto the pavement I can tell the difference. Unless you had driven the truck before and after you would never know other than how stiff the front end is along with 1-1/2" front and rear sway bars, it does ride pretty stiff now in the front and even more so after removing the 4'x8' toolbox in the bed.

Don't care much for the 1972 4 door Cadillac yacht ride, you guys may like it in your trucks and I can clip clover leafs and long curved freeway ramps at a very quick pace with no white knuckling. No road races just very good stability, safety in a panic (IF I ever do that) situation for a 7500lbs. truck.

I do need a rear track bar as the shackles I installed flex and new leaf spring bushings would help also, I have rub marks from the bolts on the frame....

I switched from stock to MA mounts and noticed absolutely no difference in the front end. Changing shocks always has a noticeable change for me, but the MA mounts didn't affect handling for me at all. But I have a 4x4...

Update:

The 4x4 has more mounting positions/bolts for the IFS pumpkin so that will make a difference. Also, the mounts have settled in so I have less rattles/vibrations in the cab with the idle reset to 710 RPM. The driveline clunk that is common on the 2001-2010 truck has not been present since installing the Merchant engine mounts and an Energy Suspension polyurethane transmission mount awhile back and this was expected.

So the combination of the polyurethane Merchant engine and Energy Suspension transmission mounts have done what I expected and then some....

I swapped my driver's side to a MA tonight. The whole time I'm thinking that I need to find the 4 page thread where Mike swapped mounts on the Elephant Well, except for when I snapped a bolt and was bitching as I took out the mig welder, LOL. 5 min delay of game, hahaha.

Yeah mine vibrates the whole damned dash now, and it takes bumps better without the engine feeling like it's bouncing around up there. I'll find an idle that works for me, and I won't go roadracing with my new engine-as-a-stressed-member-NOT, LOL.

Miss ya', Mike!
