Was 4 wheeling down some logging trails on my parents property and caught a stick in my driver side outer cv boot. Was looking at oreillys and Precision offers CH8256ET. Didn't know how long these have been offered but seems interesting. Might have to do a slight upgrade

If you get the extended travel, is it possible for you measure the length of both stockers and extended travel ?
Wonder how much longer they're.

Hay All, there's a Fleet Pride in Santa Rosa and all over CA they specialize in CV Shafts, they get allot of there shafts from Canada.

Been looking into these and I'm very interested. I believe the TRX actually has a similar style telescoping spline mid shaft. I'm thinking this should allow for an extended travel shock hopefully like Kores old kit. Way cheaper than a Dirt king kit and without the need for wide fenders

I'm also curious about how we can get every bit of travel from our front suspension without going to something like the Dirt King set up. What is the biggest limiting factor on our trucks? Is it the CV axles or a combination of components?

On the stock suspension the deliberate limiting factor is the strut itself. If you take the strut out of the equation the next limiting factor is the ball joint on the upper control arm. The next limiting factor after that is the inner CV cup, and exceeding its travel results in a cracked front axle housing. A CV with more flexible joints will generally also be weaker so if you get a CV that has a machined inner cup for higher offset angles it will also be more likely to break when you exercise that angle. If you solve all of those limitations you very quickly come up against the limits on every other component of the front suspension (lower ball joint, outer CV angle, tie rod inner and outer angles, control arm interference, tire interference, etc). It is unlikely you'll be able to get more than a 10% increase in suspension travel on stock geometry and stay reliable no matter what you do.

Stock you get somewhere around 9.5 inches of total travel with roughly equal up and down travel available. When you lift using just lift struts (bilsteins, fox coilovers, whatever) you generally don't change anything significant about the range of travel just where static ride height is within that range. In practice that means a reduction in the effective suspension travel because it takes a lot more weight to completely compress the suspension and use the whole range of motion. So for maximum suspension travel on stock geometry you should aim for no lift, or a 4 or a 6 inch bracket lift with neutral angle CV axles/control arms.

I do believe Kore's old extended travel kit had high angle CVs and upper control arms in order to get 13 inches wheel travel. Could.be wrong but as far as I saw those seemed to be the limiting factors. So I'd think these CVs with some good UCAs and maybe we could get some good travel. Kore's CVs only replaced the inner joint to go from something like 19 degrees to 40. These claim to be 47 on both inner and outer joints and also telescoping which should help some with angles, idk how much but should help. Also I believe it runs on an 8 bearing joint compared to the normal 6. Personally I'd love to try a set and probably will, hopefully with a custom set of shocks to extend travel. I think 8 inches of shock travel to be somewhere around 12 inches wheel travel

I'd be extremely interested in hearing about that set up! Somewhere around 11 to 12 inches of front travel would be perfect for my needs!

The KORE Minotaur suspension had longer upper and lower control arms and longer tie rods and longer CV axles. The bendy bits swing in longer arcs resulting in longer linear travel. You can't achieve that with stock lower control arms or CV geometry.

I think MrJHSN was talking about the High Angle CV joint kit by KORE for the 09-11, not the Tactical kit used for the Minotaur.
The High Angle was meant for a more Overland and soft crawling use, as specified on their tech sheet it wasn't meant for racing. (Can't find the article right now, will update my post if I finally find it)

Yes I was talking of their high angle CV Kit, the got 12 inches of travel out of it. I thought it was 13 but I was wrong. Their Minotaur kit got 14 inches travel. They only had a high angle UCA and CV axle from what I’ve read. Sadly its not on the market so not the easiest to get specifics. Working on ordering 8 inch travel shocks at the moment. Be an awesome mid travel kit

Would the current hardware limitations not prevent the longer shock from utilizing the additional travel potential?

Can't wait to see how it would turn out, been thinking myself for a custom high angle with 8 inch stroke, keep us update.
