    All wheel drive transfer case

    The The TC I'm building is a complex device and I haven't really given enough information out yet to fully understand it. That is my fault not yours. Im into road race where operating smoothly is critical especially in the rain when the outside temp is reading 32 deg F and the sun is...

    All wheel drive transfer case

    The part that I feel like you haven't factored in is where I mentioned the bias gears that will be more or less quick change for racing/off road application. That is where you're pre load comes from in the TC I'm building. You are discussing axle diff function. Im not building the diff to sell...

    All wheel drive transfer case

    I think you are misunderstanding how torsen works. It will not allow a single side to turn by itself. That is the actual principal of the design. When a wheel becomes unloaded and begins to spin freely and the ratio allotted by worm gear angle is reached(which happens instantaneously) the...

    I did a deep cleaning detail on it a week and a half ago. It just rolled 90k and you can see I take damn good care of my vehicle. Sorry I had to "go to town" to upload those

    I will also say this.....I daily a 2015 eco diesel and have some tight 90's on my roads, like recommended 25mph 90's and I've started testing the ole Borg auto 4wd. In a month i think I've eaten the clutch pack and I only request it in 4 turns twice a day and when it rains. Had a helluva storm...

    You're welcome to text ne Kyle, I'm open to filling the need across the generations. 8176143875 I live in a bad area for my phone. I like it that way but it makes text and email essential. I won't call more than twice and not get an answer before I look for help elsewhere if ya know what I...

    All wheel drive transfer case

    Here is the basics of torsen. While this is a different design using spur gears to merry the axles into equal power division the one im using does the same thing where the worm gears are engaged into each other in the center. At first I demanded the type in this video but after more education...

    All wheel drive transfer case

    If 1 tire goes airborne with this differential it won't matter to the other axle because it WILL lock itself solidly and force power to the axle with traction. That said.... if you don't have locking axles and get 2 off the ground that's the fault of the axles not transferring side to side...

    All wheel drive transfer case

    This one will handle the torque. Im not going to skimp on trying to fit the weight envelope because in this application it needs to be reliable pulling heavy loads all day every day with power adders on the engine. I am including the planetary reduction system for hi and low range! So don't...

    All wheel drive transfer case

    He thinks it's gonna do better on fuel. I disagree because the front is being turned by vehicle motion all the way to the separation in the factory unit. All the rotating mass is in motion either way. . Another guy says he wouldn't buy it if he can't have the option to do burn outs here and...

    All wheel drive transfer case

    Very good points. I see you do your homework. I am an OEM when we design new products like this we get the other manufacturers involved with the engineering aspects of "moment loading" a mating surface of their product so we are in agreement before we begin building a prototype that using our...

    All wheel drive transfer case

    If you have a 3rd gen case with the input shaft so we can reference it for fit up to the trans output you'd be willing to send me I'll return it after measurement and cut you a deal on the prototype to test and keep to push as hard as you wish. The diff is basically a Dana 80 so we already...

    All wheel drive transfer case

    I got us the torsen center! It's really impressive in person. Im going to make the back of the case where you can remove a plate and the output shaft cone and change 2 gears to correct drag racing torque steer if needed without removing the whole thing and splitting the case. Here's a crappy...

    Good news! After months of work I now have a patent pending on the all wheel drive conversion for our trucks. HOWEVER I am building the first one to go in a 2018 for testing.

    Moving the engine back behind the front axle.

    To be honest I have no idea.... she just popped in my head lol I just miss the 70's . Life was awesome back then
