Matt, be aware that if you remove the 4 speed you will be required to pm me your address so I can send a couple skirts your way...

I went through 2 of the Korean gear sets in my 18 splines, both kryo'd and mikronited. Both broke, 3rd, at about 35-36 passes in a 3300lb a body running 10.40's. That was with an adjustable clutch. The clutch change helped prolong stuff until the trans upgrade.

I'm on year 6 of the adjustable clutch and still no racepak or anything. Am I leaving something on the table? Probably but I don't run class stuff so if I was that concerned with a couple hundreths I'd put myself on a diet.

Good luck.
