Actual they have V pro lifters that will fit in a Gen V that gets rid of the DOD, they just are not listed for that cause they don’t drop straight in. IRC it takes a .050” longer pushrod to make...

Here is the Blower shops troubles with SM. I recalled wrong, it wasn’t the drive with the name on it, it was the blower. SM made it, and has the TBS logo right on there.
