What kind of compression travel should I be seeing on the right rear shock on a dirt modified with a a 4 bar shock in front?
You have to learn the rules of the game. And then you have to play better than anyone else.

not trying to be a pain, but are you looking for the shaft displacement? (axle movement + birdcage index) or just the axle movement relative to the chassis?
Mediocre is not good enough... ever.

Shaft displacement is what I was thinking. It's the easiest to verify with the travel indicator. I know there's a number of factors that will make the axle travel different with the same shock travel. I'm getting a little less then 3" compression at the shock. I'm not getting a balanced weight transfer and think I need to free up the rear a bit more.

I usually see closer to 4" on the "travel indicator" and around 3.5" reading the dirt ring. I probably trail brake too much and keep the car up on the LR forcing it inactive while the RR moves.

Thanks Gavin. So it looks like splitting the up and down travel on a 9" shock should be acceptable. I wasn't sure if it might be just the opposite as the right rear where you have more down travel than up on the shock.
