Mike I do a lot of Allison builds, how do these springs work with the Ratiotek PR spring? Or PR spring and shim? I'm assuming these springs only fit the 01-10. I would like to buy few sets I will give u a call Friday. Thank you for your time.

The Ratiotek springs are my springs. My shift valve springs and HC trim springs enhance the whole set up.:thumb:

No problem to use in an LML?

STOP right there. You cannot use this in an LML. The LML will require the use of my pressure regulator system with valve body adjustable mod. Totally different strategy on the LML. You will hurt the LML with the wrong mods.

Good thing I asked :)

No worries, the one LML customer enquiring about this already has your PR kit in it. Whenever I get him booked in in the next month or so, I'll discuss with you prior to even attempting!

I just got done installing these in my LLY with a built trans and its a big improvement quicker shifts. seems to downshift quicker also. Oh and mikes LML mod is a very good mod also. I have it in my 11 lml and it makes it a lot better with firmer shifts

I got my two sets today; thanks. Mike! I see 6 white springs and 5 small ones... IIRC there's two small needed per truck, so there's one to save my ass WHEN I drop it and lose one? :roflmao: Good lookin' out :hug:

Just putting this out there....When I was there last Monday getting the springs installed Mike had a bunch of the springs in stock. And he has a new way of shipping them too. So if anyone wants just the springs get ahold of mike.
FYI... The springs are worth the install. My trans shifts so much better now. They really shine at part throttle or just regular driving around town.

Lol. Yes when you can control your self you will feel the the difference.

Or not....... When I first got my truck I had mike l install a trans go Jr and pump rub plate. Drove like that for a couple years. I got used to how it shifted in that time. Last year I got the trans built by mike l and again got used to how it shifted. Last Monday I got the new calibrated springs installed and I noticed how different and better it shifted.
If you never felt his it shifted before the springs and after I don't know how you will be able to tell the difference.
Don't let me discourage you from getting them though. You should get them! There are other benefits of adding the Mike L springs. But I can not disclose the tech info mike has told me about the springs. If you want to know more you will have to talk to mike about that.
