I used it and it worked great! Steve Conley ran some 9.30's on them at 168mph and they are still working fine.

is this the set that still uses your stock shafts you just replace everything with the MFACTORY set?

V-SPEC 1

I believe so.

I've installed quite a few and none have had any problems.

No reason to use the G-Force shifter with the PRO Synchro gears as you still have to use the clutch. The 3/4 set works with the stock shafts. The 1/2 uses the MFactory mainshaft. Whether you use the 1/2, 3/4, or 1-4 you can still use stock 5th or a cuff.

I.C.C.

I plan on picking up the MFactory Pro Syncro set once I get my tax return... Heard nothing but great things about them, and the folks at MFactory seem to be very helpful, and customer oriented...

we love our sets they have never let us down just the damn bearings we keep killing! but we found out what that problem was! at least we are not grenading cases!

cool only reason askin i hurt my motor on a misshift 2-3-2 last season not tryin to have it happen again im usin a stock tranny w/cuff the g force shifter is what im lookin into and that was my question for the guys running them with stock syncro engagement

I have sold them to a couple customers making over 700 and they have had no issues. They love them.

If you're currently having synchro problems, thats not going to change. What's going to change is the life you get out of the gears themselves.

i have 2 cars on the synchro set and havent had an issue yet both cars make 850whp+.I just ordered a 3rd set to have a back up for 1 of the cars.1 set we didnt get the input shaft and it has held up so for but havent hit it hard yet.The full set car has gone 9.53 at 163 and the car is going to P.R for the next couple of months to run the 3 races coming up there so they wanted a back up.

speeddave

feel like sharing what solved the issue?

We had 2 pinion bearings fail but our issue was no cuff was being used at first once the cuff was installed problem solved.

Improper shimming, weak or used bearings. Cuff helps a lot but is not a necessity.

boostede46

quick question, how long do the carbon moly synchros last on these gears?

not sure yet but we think its because we never ran a cuff! we will see soon!

The G force shifter has nothing to do with using the clutch or not. Most everybody using the G Force shifter uses the clutch anyway. I have used mine with syncro boxes and dogboxes. I would reccomend using the shifter no matter what tranny you use.
