Contrary to popular belief, a 0 degree rear truck does not help with stability, in fact it makes it unstable.
The rear truck should be able to turn a bit, it can’t be dead.
Wowgo used a DKP in front and a 0 deg rear truck for their prototype board, some people who tried them said it gets unstable at higher speeds.
DKP! They’re all unstable at high speeds - that’s the issue right there… maybe they should try the same with standard RKPs. Btw i just had a speedrun with my FWD at full pelt - reached 39km/h on that tiny contraption… no speed wobbles even with crappy 50deg (flipped hanger) trucks at the rear. When the throttle cuts abruptly (that’s when i get wobbly on my normal RWDs) - total stability - it’s crazy good. I can imagine a lower angle or zero even and what that would do. I believe it has much to do with putting all the weight in front of the deck.
I do agree that some suspension at zero degree angle is required to stabilize the deck over bumps, just like the rear wheels of a car - they go up and down instead of turning left or right. They’d be considered zero degree as well. Maybe that was what was missing in this wowgo prototype, in addition to the always sketchy DKP at higher speeds
He’s in a different speed league, guys. Let’s keep that in mind as we’re offering him suggestions on how to improve his boards.
Yes sir!
Me and my Exway are already in the hedge.
Sexway
I don’t care I’ll race him, and I’ll race you too, and fuck I wanna race you both 
It would be fair to mark this as your own opinion. Many riders feel very different about DKPs.
Apologies, I was referring to DKP at high speeds. Downhill riders do not use DKPs.
Everybody who has gone 50mph on DKP trucks powered “sound off”

Yeah, that might be a different story. I find them up to 30mph stable, but never had the chance to try them out at higher speeds, but I will.
It’s on! Race Raine first, and then at your funeral, I’ll race your relatives to the ritz cracker appetizers.
@FastBoard I love your videos, it’s straight up DH on flat roads; with a bit less slidey slide.

We need you to come down to SoCal! Maybe do the streets of Lancaster race like @MoeStooge suggested…
One day… 
Dear Raine Kent,
we need MOAAAAAAR of your awesome stuff, right NOW!
I’m pretty sure @BluPenguin has done 45mph. Correct me if I’m wrong… It ain’t 50mph, but there’s definitely something to be said about skill in hitting those speeds on cast DKP trucks…
He’s in your area Brandon. Definitely somebody who would be able to hit 50mph with ease on a SRB IMO.
Can you tell us about the price range you are having in mind?
Just round about 
double fucking kingpin
