Supershafty CP43

[Col_Sanders]

These caught my eye a couple years ago but the price tag pushed me away. As of today, a front axle is $439.99 and a rear is $269.99. When you can pick up a new set of take off F10 portals for $200, the $700 price tag is pretty high. But you fully deck out those F10 portals things change. A new front and with all the aluminum upgrades is $465 from vanquish. Rear is almost $350.

Anyway, figured id give some pics with other axles for comparison...

They have more caster built in than the F10P and AR45. They also have a mm or two more ground clearance than the F10ps, and a smoother profile so they should slide over rocks better. They are also a few mm wider.

The CP43 universals have much larger pins than the F10Ps and the ears have been profiled to allow better steering angle. Stub shafts on the CP43s are smaller than Vanquish, as is the bulk of the axleshaft. The part i keep breaking on the F10P is right outside the spool and theyre the same size there. Im not a metallurgist so cant tell which shafts will actually be stronger.

I just bought the housings, which come with everything you need to swap ar45 or Capra axles over, but they came with no rear upper link riser and the high profile front upper link mount, which wont work for 4 link. In hindsight i should have just bought complete axles and sold the ar45s.

The strength of the axle shafts is not just about the metallurgical properties, it can be about stress distribution.

If you are currently breaking the axle shaft just outside the spool where the shaft cannot be made thicker or bigger to strengthen it, then making the shaft outside of that a bit smaller can actually move stress from the over stressed breaking area out to the long part of the shaft where it was not being stresses to the maximum. If done correctly it distributes the stress enough that no 1 part is overstressed eliminating failures.

Basically, the skinny part of the shaft flexes a bit more taking stress away from your failure location and stopping the failure from happening or at least increasing the time until failure.

I've wanted a set for a while, to go with the SS CP44 Capra axles I have on my G-Shot. They are awesome, but pricey! I have never had an issue with mine!

Ive broken two. First one was entirely my fault. Winch line got wrapped around the tire on gate 8 or 9 and i had seconds before timing out so i sent it and SNAP! The second one was odd. Had not been in a bind or anything all day or the day before. It broke on really mild terrain. No noise or anything. Tire just stopped pulling.

I like using the same axles on multiple rigs. If these hold up i might but another set.
