    Fortin FRS5 Questions

    McMullen has my trans apart now and I'm waiting for his call letting me know my r&p and gear stack ratios and options. I'm just mulling over what I can for now. I think I have a 3.88 now as that is what the extra R&P I have is. Any idea what gear stack ratios might be available? I know I...

    That is what I was told by the gentleman(not Doug) at Fortin. No doubt a lot stronger than 4.88 and 4.37 somewhere in between the 2.

    Gray Area 934 Midboard Bearing Preload Setup

    So,what are the consequences of way too much preload a person might ask. Here are a few pics that show the onner and outer race being bound up so bad the inner race and bearing were locked together for enough time to actually spin the inner race on the hat and the boot flange registers till...

    Gray Area 934 Midboard Bearing Preload Setup

    A day spent not learning something new is a day wasted. :) I have always been under the impression that bearings were made to a spec that was a constant from brand to brand. In other words a ll225749 /ll225710 from Timken or Koyo or whoever would for all intents and purposes be the same...

    Fortin FRS5 Questions

    As I posted,I will call again next week but will request to speak to Doug himself this time. I'm sure it was not Doug I was speaking to a couple weeks ago as it sounded like the gentleman I spoke to wasn't really familiar with their offerings. Maybe newer help? They have always been very helpful...

    Fortin FRS5 Questions

    1-Does anyone have a current list of 1-5 gear ratios available? 2-is the 3.88 ad 4.37 the only r&p available for it? They have a 4.86 on their website and it has been on there for years. When I called a couple weeks ago they acted like I was crazy and said they never offered it. This is from...

    No-Lift-Shift, What is it? (Paddle Shift Info Added 9/17/24)

    Unless it monitors shift drum rotation to verify shift is completed before resuming power I would not be interested. It appears to be a time based only unit .

    I agreed with a bit of that but for the sake of argument,take the 300 percent as fact,that would only be 90. A lot less than 250+

    Gray Area 934 Midboard Bearing Preload Setup

    Maybe you missed it but the .050 spacer is what I was sent either by you or GA along with the koyo replacement bearings. I was advised to use it between the hat and bearing. Sorry but I will do my own work as usual and get it right. I think I got a correct description of how tight these things...

    Gray Area 934 Midboard Bearing Preload Setup

    What I posted is true. Your description is also correct. Any expansion of the alum hat will not affect the preload. As for the .125 plate it will make for an inadequate cv bolt thread engagement. At least it would with the cv bolts the hubs came assembled with. I will counter bore for hardened...

    I'm going to reply to this post first as it is the simplest. I will make my comments in bold above. I will try my best to not disparage any parties. That is NOT my intention here.

    The bearing carrier is steel just as the cv and bearings. Any expansion pretty much cancels out any other expansion. The aluminum hub is pretty much irrelevant .

    No-Lift-Shift, What is it? (Paddle Shift Info Added 9/17/24)

    Here is a vid using their paddle shift system with a BMW v10 4wd in the mud. It's a paddle and not the no lift only system like I am talking about. I don't have a fancy engine management setup..
