does anyone make a HD rear transmission mount for JK? The stock mount seems way too light/flexible. I can grab the rear DL and move the trans./transfer case by hand quite a bit. It's this weak mount and drivetrain movement that makes the stick want to slap you in the face. I know they all do it.....because they all have the same mount, but it's not right. Any suggestions? Also is there a programmer that improves the throttle?
