Stock & Super Stock 4-speeds
 

What is the prefered 4-speed in Stock and in Super Stock?

If I remember correctly, stock was clutch assisted and super stock was clutchless. Is this still correct?

Re: Stock & Super Stock 4-speeds
 

SS allowed clutchless, Stock not yet . G force ,Liberty ,Jerico all sell clutch +less ---Trevor

Re: Stock & Super Stock 4-speeds
 

G-Force, and Jerico sell clutch assisted and clutchless. Liberty clutchless only, but will modify stock trans for clutch assisted. Who's best? Depends on who you talk to. They all work well.

Re: Stock & Super Stock 4-speeds
 

Liberty makes the Equalizer (clutchless with dual cluster shafts) 5 speed that is legal in Super Stock. Liberty also makes an LSC 5000 (single cluster) and LSC 5100 that are legal in stock. The LSC 5000 and LSC 5100 are very similar in design to the old Doug Nash split clam shell type transmission. We run an LSC 5100 in our CobraJet, but run it in a 4 speed configuration. If you run any of the split clam sheel transmissions as a 5 speed you will have issues. We have had zero breakage problems running the LSC 5100 in 4 speed configuration.

I see alot of guys running the Jerico DR4 & CL4. And also the Gforce 101A. Whick looks basically like the Jerico. The Liberty 5100 is also a strong looking trans. Seems like i see most guys running the Jerico down here in the south.

Re: Stock & Super Stock 4-speeds
 

Jerico had the market cornered for a lot of years. Gforce looks likt a T10

George Wright we run a LSC 500 as a 5 speed , and before that a Nash . Are there specific concerns you could share ? ---Trevor

Re: Stock & Super Stock 4-speeds
 

Didn't know Liberty made stock legal after market trans. Sorry for the mistake. I'd have to say it's probably a good one.

Re: Stock & Super Stock 4-speeds
 

Liberty's clutch shifted trans is based off Nash virtually everthing will interchange between the two Liberty has updated it w/face plates.
T101 is made by several G-force calls it something else rated at 1000 hp have a basket case tex racing version going to fix and use in stocker

I understand everyone has a preference or an opinion, but are there any specific or distinct benefit to the DR4 Vs the G101A Vs the LSC 5000/5100 ? Thanks

Re: Stock & Super Stock 4-speeds
 

The Nash has been around forever.....its just that since he left years ago , its now called an LS5000 by Liberty and a GF-5R by GForce .
I mean after all , whats a Liberty clutchless but a Nash laid over on its side with another cluster added...........was that a revolutionary "no brainer" or what?:D

Re: Stock & Super Stock 4-speeds
 

You need to look at the inside of a GF5R side by side with a Doug Nash before you conclude that they are in any way the same transmission. Just because they look the same from the outside doesn't mean much. My old Doug Nash broke on regular intervals, the GF5R is indestructible.

Re: Stock & Super Stock 4-speeds
 

I dont know WHAT you were doing with the Nash , but I run one and its a damn good trans...........faceplated.
They are the same , albeit for the upgrades to Nash's design........and yes , I've looked at them all. It was easy for G Force and Liberty to make the upgrades to a proven design. They can call them whatever they want.......to me they're all a Nash;)

Re: Stock & Super Stock 4-speeds
 

The biggest improvement between the Nash and GForce was the internal rail shift mechanism that makes it impossible for two gears to engage at once (which happened to me once). The Long shifters have been a big improvement over some of the older stuff also. Since the '80's, I've advanced from a Nash (non face plate type) to a G&G (which was the trans that evolved into the G Force) to a G Force clutch assisted to a G Force clutchless. Each one of these evolutions was a significant improvement both in performance and reduced maint issues. I'm not at all bashing the Nash, transmissions wouldn't be where they are today if that design didn't exist. The thing I don't like about the clutchless designs is that they are a pain to drive around in the pits. You have to strong am the shifter to keep it from popping out of gear, then you have to come to a full stop to reengage it. Really sucks when someone is right behind you trying to figure out why you're holding him up.

As long as we are on the subject of obscure racing transmission history. The whole face plate and clutchless technology (which was a huge improvement over the old dog teeth that were constantly wearing out and burring over) was first being experimented on in the 70's in what was called the Phalanx Coupler. I don't recall the name of the guy that designed and built this but he retrofitted a Toploader to a clutchless design with an early faceplate design. The parts were too small and weak to survive for an extended period but the concept is what we are still using today. Actually, I think there were motorcycle transmissions that had the design earlier than this but the Phalanx unit was the earliest version that I know of that integrated it into a full blown automotive race transmission. Does anyone have any further history on this?

Re: Stock & Super Stock 4-speeds
 

Jim, At one time I actually had an order form/tech sheet from them.I rememember they recommened using a Thunderbird driveshaft because it had a rubber dampner in it to reduce driveline shock.

Re: Stock & Super Stock 4-speeds
 

I remember that there was a magazine article on the Phalanx conversion for the top loader back in the 1970s, probably in SS&DI.

Re: Stock & Super Stock 4-speeds
 

I had the magazine as well, I bielieve they were called "Phalenx Star Couplers", or something like that. Based upon a motorcycle design. Certainly a big improvement over the old style "crash box" or "Pro Shift" versions, and much, much less maintanance required.
