Side Shift only or is one for a Tail in the works?

Sweet. Nice boots! (IMG:style_emoticons/default/beerchug.gif)
James talked about this in the Paddock a while back. I think Brumos had used a similar thing on all their race 914s - there were pics. The little solid rod slides in the big aluminum bracket with NO PLAY for more precise shifts under high Gs and chasis flex. Use the *Search* in the Paddock on 1st gear lock-out for the 3-4 page thread. Could a hollow shift rod be used - those things are heavy!

Ah, it would work great with that broken one as the new support has its own bronze bushings and no longer uses that part of the casting.

Side shift only.

The advantage is that it is a true no-slop shift linkage. Due to the way that the side shift rods must angle as they rotate, just tightening up the stock bushings leads to binding unless they are hourglass shaped, and then they have a very small contact surface.

This systems takes out all the binding in rear and supports the rod on both sides of the cup.

The front (firewall) is taken care of by a nylon composite spherical bearing, allowing the off axis motion and low wear against the new chromoly shift tube.

I will be selling the kit for about $460.

There is some fabrication required. I did not want to force you to replace parts that you already have and drive the price up further.

You will have to cut the solid portion from the front of your own shift rod where it attaches to the shift head and weld this to the new shift tube. It is not critical (+/- 1/4" or more in length and no rotational alignment needed), so it is easy to complete.

I do not (at first) plan to supply the tube portion between the u-joints. This is the part that will be bent for a 4 cyl, straight for a 6 cyl, and longer for a V-8. Because the u-joints allow rotational re-alignment, this portion of the linkage is not as critical as the original design, so "close" is good enough in making this part, as long as it clears everything.

So, to answer my own question:

-6 = yes, depends on the rod not supplied. That rod must clear everything. As long as the tranny has the side shift consoule it should be good to go.

Correct?

Does taking the slop out of the linkage relate to faster shifts???
With less grinding?

Oops - trying to answer too many questions.

Yes, a straight (or very close to it) tube (not supplied) will allow it to work with a /6 with side-shift.

If the grinding is due to worn synchros, then no. If it is due to missing the gear position, then yes.

The shifts will be more repeatable - the servo syncros will still limit the speed of the shifts.

I would think it would have to help in someway. I'm on board, gooooood work!!

Wouldnt the application of your Rennshifter alrady address this?

The RennShift addresses all it can from the shifter (which is the biggest gain) and also adds the spring gating and reduced throw, but there is still something to be gained in the connection between the shifter and the transmission.

James: Looks awesome! However, I bought the shift rod kit from Patrick Motorsports last year. I wish now that I had held off buying the Patrick Motorsports kit as I also purchased a Rennshifter and I much prefer to stay with products from one supplier that are engineered to work together. How does your kit differ from the Patrick Motorsports kit?

My firewall setup is the only one that offers a no-bind bearing with appropriate materials to last a lifetime and a boot to keep everything clean.

The only way to prevent bind in the rear rod is to separate the rear from the front using two u-joints. This require the additional rear support at the console.

No, as the oval rod attachment would end up right over the u-joint. The new boot is included in the kit.

if this is a *fix* for the guys that have to run no boot at all due to a side shift coversion, that's a BIG bonus. nice product james.

wow! very cool stuff!!!

any firewall to trans full installation shots (with and without covers)?

very cool. thanks for bringing more products to the market...

and if its anything like your rennshifts... it will be A+

james, quick question:

when will this be available?

(might have missed this reading through this thread)

i'm asking because i still need to make a custom shift rod for my /6 conversion and if yours is available soon, i'd rather buy a complete assembly from you ...
