DarkSoul HPI Baja 5SC v.4 Dog Bones
Finally an alternative to the stock bones and drive cups for the HPI Baja 5sc. Yes HPI increased the size and strength of the new bones and cups on the 5sc but it is still not meeting the demand of the large scale bashers so DarkSoul did something about it. They took the best dogbone and drive cup reinforcement option on the market and adapted it to the 5SC size requirements. Read more below.

With the 5mm round pin, you are applying all the drive pressure on a very small area only a few thousandths wide on the tangent of said round pin. This is pretty much the equivalent of a knife edge. Over time, this will wear to a somewhat flat surface, but by this time, you have grooved either the drive cup, or the drive pin, or a little of both which in turn now creates slop, this slop is potentially disastrous since now the drive pin can bang back and forth when on and off the throttle creating a severe stress point.
With our new design, you get many advantages. To start, the drive surface of the pin is 5mm wide, so there is a wide flat surface now pushing on the drive cup. The center part of the v4 cross pins are 6.5mm in diameter, this added diameter allows the pin to self-center inside of the drive cup without being able to slide out in either direction, so no set screws are needed. The cross pin will rotate so there is no binding while the suspension articulates through its range. As well, you can continue to use your stock drive cups, although now that the pins/bones are all but indestructible, you may want to beef up the cups with some TOOBZ.
The one thing to keep in mind however, is that YOU MUST RUN GREASE AND BOOTS. The cross pin needs to have lubricant on it at all times. We strongly recommend Fast Eddy grease.
Note:
Failure to lubricate and protect these pins will increase their wear unnecessarily. If using the DarkSoul TOOBZ on the drive cups, it may be a little tight to get the bones in the slots since the TOOBZ slightly squeeze the cup, but they will go in with some pressure.
