How do I adjust my C7 front truck?
The first thing to notice is that there are several extra bolts on the C7. DO NOT ADJUST THE FRONT PIVOT BOLT! This is the bearing for the swing arm and it wants to be snug but not too tight, generic viagra as you can overtighten this bolt and damage the bearings inside. The way to adjust the internal spring which controls the arm tension is with the 1/2” Spring Bolt located on the baseplate at the back of the truck. It’s the same size as the wheel nut, whereas the Pivot Bolt is the same size as the Kingpin, 9/16”. You can adjust the Kingpin Nut as well, and this will change rail stiffness. Tightening the Kingpin Nut will stiffen the rail-to-rail action and also reduce wheelbite, while loosening the Kingpin Nut will soften the rail-to-rail action.
How much does adjusting the C2 back truck change the board’s performance?
Adjusting the C2 is a big factor in adjusting the feel of your board, as it is the other half of the system. A looser back truck will probably feel more harmonious with the front C7 or CX, as these are very loose trucks as well. This is good for easy pumping and tight turning. If you are looking for more stability, tightening the C2 back truck will affect the overall feel dramatically and make it much easier to push. As a factory setting we generally prefer the tighter setting for the C7 Kingpin, medium to loose setting for the C7 Spring and loose setting for the C2 back truck Kingpin. This is optimal for surfskate performance, which favors easy pumping and tight turning.
I just bought a pair of the CX trucks but am dismayed at the kingpin hanger height relationship. The kingpin is taller than the hanger (or lower than the hanger if your riding the board). Please note I don’t pretend to understand all that you guys must deal with in getting these trucks to do what they do, but couldn’t help while researching to note the open bushing cup area, and expect the CX to allow more clearance between the top of the hanger and the kingpin.
I’ve been riding the C7 for about 2 years and just recently started riding it in parks (I get loads of comments). As I worked into grinds with the C7, I was always nervous about the kingpin grinding simultaneously with the hanger (mine are loose enough that the kingpin nut is about the same height as the hanger) and thought the CX would solve this.
So, I can’t hide my disappointment, even wondered if somehow I had received a truck with the wrong kingpin (even though I don’t know how a shorter kingpin would accommodate the bushings)?
See attached photos of the newly grinded C7 truck along with the kingpin/hanger height disparity on the CX truck. Any comments or solutions are welcome. I plan to start grinding on the CX but am even more nervous than I was with the C7.
Thanks for writing in with your question. Stoked you’re having fun in the bowl!
Yes, you know we did a lot of work to get the CX to have that fast pump, and part of that comes from the taller bushing set. We made the new CX so it had the best pump possible for hardcore surfers, and that ended up raising the kingpin. Now, for your application in the bowl you are apparently tightening the bushings a bit more and exposing some threads on the kingpin, which means you could have a slightly shorter kingpin. And if you wanted it even shorter you could use a shorter top bushing, which would restrict the range a bit, but still okay in the bowl.
I’m not sure if you have any tools to modify your kingpin (by grinding or belt sanding it down a bit, or pressing in a new shorter kingpin) and if you do that’s great, let me know how it works. If you don’t, we can help you out by sending you one we modified here, let me know what you prefer.
Either way we can work this issue out and get you grinding with confidence!
Thanks for your response and willingness to help out. I took the kingpin and simply flipped it upside down in the truck (this eliminated any need to grind the kingpin down), then replaced the top bushing with one a bit shorter. I haven’t yet tried it, but it looks good. Thanks again for your help!
That’s great, I’m stoked you have a solution that looks really good. Since we have a thinner bolt head than standard 3/8″ bolts it probably works even better.
Let me know how you like it once you’ve had a chance to ride it.
