No, no rules to dictate my choices,  only rule I know of is N/A and run what ya brung and hope you brung enough.  Mostly run 1/8 mile stuff. n/t , grudge, and quick 8 - 16 . I'll only run 1/4 mile about 4 times a year. Once I retire in a couple years I may run with the pro stick association guys some.

I already sense the flames but if you have a choice between a Liberty Extreme 4 speed and a 5 speed clutchless, choose the 5 speed. I race in NHRA SuperStock with a Liberty 4 speed clutchless for the last 10 years and can verify that maintenance on a 4 speed is, exponentially, higher than a 5 speed. The problem is universal to any manufacturer's 4 speed clutchless; the gear ratio spacing is simply so wide on a 4 speed, by comparison to 5 speed spacing, that gear rpm equalization damage during the upshifts accelerates to the point that 3rd speed dogs and slider require service (replacement) between 12 to 20 full rpm shifts. This is NOT an issue with the 5 speed boxes, as SuperStock users report that they easily go 100 runs without requiring service. You will hit the B.S. wall when you attempt to verify what I am reporting from mine and several other S/S racer's 4 speed experiences. Don't misunderstand, my Liberty Extreme is a brute and this is the only issue I have ever had with his trans. Additionally, don't miss the fact that a ProStock car is 2350lbs, requiring a lot less 1st gear ratio than a 3300lb SuperStock car which calculates into causing those gear spacing statements made earlier. Choose wisely, good luck.

Curious to know what you shift your Super Stocker at? What fluid are you using in the trans?

I'd rather not disclose the exact rpm shift numbers on an open forum due to the negative conversations generated but let's just say high, very high. If you viewed Ray Paquet's 2021 Indy YouTube interview by Evan Smith, the numbers he stated are ballpark to where we are all operating.
Liberty recommended Mobile 1, 75W-90 when I purchased my trans in 2010 and that's all I've ever used without the slightest evidence of lubrication failure. I recently noticed that Liberty is now marketing their own branded gear lube so I assume that is, likely, the present recommendation.

No worries, I've talked with Ray, and Kurt neighbor about how high they shift theirs. A friend that ran a Liberty for years, switched to Redline shockproof, and he said it cut down on maintenance quite a bit. That is what I plan on running. i talked with Liberty about it at PRI, and they said it was fine to use.

Thanks for the info. Liberty promised that it was a unknown problem when I brought it to him and he would get it fixed.  I tried multiple iterations of shift dog counts (all at my expense, I might add) and all it did was make matters worse. Actually, the highest shift count achieved was with a 3-dog setup that Liberty said would never work but it was the only one he had that I hadn't tried. I tell you this so you won't be drawn into their revenue machine when the 4 speed begins to have problems. My trans were both built with 5-dogs; he had me try 6 and when that reduced the shift count by almost 30%, he suggested 7. I requested 4 and the answer was, he didn't like making those because that's what his competitor used and I already told you the 3-dog story, but I insisted on the 3 and, somewhat, improved durability. The "company" line was that the original design had 3-dogs (5 speed trans) and Greg Anderson requested they try 5-dogs to reduce maintenance frequency and they switched all production to 5-dogs, based on Anderson's satisfaction. Again, the results are based on 5 speed applications in an ultra-light weight combination. The racers using 4 speed trans will all tell you (if truthful) that the two trans act like two, completely different, parts based on the ratio drop benefit derived from the extra gear and starting line weight of the application. The almost unbelievable fact is that, as a driver you can actually feel that the 3 dog setup shifts easier and quicker but I've only used it on 2nd and 3rd speed. No need for 1st and 4th is completely different animal and pretty reliable at 50 to 65 shifts before needing service. Breaking any internal part is almost none existent but 4 speed dog wear can be an issue. Good luck.

You can run the 5 speed if it only has four usable ratios can't you? So a 1 to 1 4th and 5th.

It wouldn't change the maintenance problem since the ratio spread percentages would remain the same as a 4speed. Additionally, you would have invested approximately $1100, or more, per trans for no benefit if you ran it as a 4speed instead of a 5.

Pretty sure Ray Paquet runs this setup in his Thunderbolt. Why he hasn't switched over to a Liberty, I don't know.

True. He runs a Jerico 5speed that has an internal "handcuff" in place of a forward gear which results in a 4speed trans in a 5speed case. Ray, along with Charlie Wescott, were some of Jerico's original testers when they were attempting to counter the Liberty Extreme 4speed in SuperStock.
