To put that in perspective, it took 12 years to sell the 21 of those kits. Took me 6-7 months to influence the sale of 9 kits. These kits are were so under rated. Quaife didnt just throw an extra gear in there and call it good. They redesigned the whole gear set in a way to prevent premature wear, promote better oil distribution and oil retention in places that desperately needed it. 2nd gear has more support on the output because it floats on a sleeved needle bearing now rather than a bushing that wears out. And then the end cap has a gigantic cylindrical roller bearing on the output side as well as another roller bearing on the input side to keep the shafts together up top. Then the cap is dowel fastened to the case which takes a ridiculous amount of precision to reproduce within tolerance for each kit to make the cap an effective structural peice of the case in respect to shaft location retention. Hats off to Quaife for this brialliant redesign. As far as the future of aftermarket gear kits, well, :guns:

I'd have to look at the ratios and see how they would work out in the 1320. I know 1st gear is a no brainer.

Hats off to you guys who ponied up the capitol for one. I never could justify the cost, but I'm sure it's a nice setup.

Jason is doing things to the trans that no one else is currently doing. When you are the only one, and guys want to keep their trans together as long as possible, he is your only option on f35's. I'm surprised there are that many who will spend $3000 plus on a trans in this community. Besides guys like you who have went to the F-40's.

You got one of the few good 07+ saab F40s that were low mileage. You did good. There is some things that can be done to strengthen it such as swapping to a regal housing. Josh at ottp sells a more affordable swap kit with all new mounts and you wont need zzp proprietary half shaft because the regal housing has speed sensor built into housing but needs slight modification to allow out stock speed sensor to be utilized. Some options for you to consider.

Actually mine is 0 miles, I see nice to have more options now but I have everything already just need the time to install, I actually would like to add lsd to the trans before installing tho but it's not my priority

Well thats interesting! How does the Regal trans compare ratio wise to the preferred 2007+Saab trans ZZP recommends? Does that one come with LSD?

So much better design than old one and feels decently lighter

0 mile!? Hell ya! X2 bonus points lol. Lmk about LSD Install when u get around to it. If you wanna do it yourself, thats an option also.


Regal f40 is pretty closebto the Saab equivalent actually. Regal 1-3 are a hair shorter and 4-6 are a hair longer. 3rd is within a few mph, 4th is about 10mph longer avg.
i agree. Definitely a great redesign. When do all the new parts come in?! Want to see this thing back in action finally!

I did did some quick math, it looks like the Regal F40 has a lower ring and pinion (3.762) vs the Saabs (3.55). When you take into account the Regal using a lower 1st gear vs the Saab (3.917 and 3.769) it would place the 1st gear somewhere near what an F35 with a 4.45 is. How readily available are the 3.55 ring and pinions? and how practical would such a swap be, if you already are adding a LSD? Sorry to hijack the thread. Very interesting the prospect of having a readily available lower mile and lower price option.
