While checking my center differential for compatibility with Evo 3 gears I lost one of the poppet balls so I left it out of 5th gear until I can get a new one.

In the meantime I have noticed shifting into 5th is very smooth and doesn't have that "notchy" feel the other gears do. So this has led me to wonder what the downsides of removing all the poppets or reducing the spring load on them would be. Potential concerns are:

1. Popping out of gear. How likely is this? Any dangers to the drivetrain?

2. Shift rails moving freely. I think 5th/R is the only one that could move at all with the other two being tied together so tightly. How much movement potential is there and are there any dangers for the drivetrain such as additional wear etc?

I'm not too worried about 5/R at the moment. There are two additional "poppets" on that slider, one for the reverse sensor and a second closer to the bell housing. I'm sure they are there for a reason but so is everything else on our cars that we tinker with. I'm just curious how much tinkering is safe with this.
 
OK, so I snagged two gears in my driveway the other day, thankfully right as I was backing out so no harm done. I installed a new poppet and will never fool around with this again. Lesson learned :beatentodeath:
