The 139 Stage 11 Skateboard Trucks from Independent.
Independent engineered these trucks to be the best hybrid of performance and geometry ever produced. By improving the modern performance and iconic look of the Stage 10 design with newly reworked geometry, Independent has created the new standard to which all other trucks will be judged.
The Stage 11 trucks provide incredibly precise turns, better stability on landings, less high-speed wobble and decreased wheel bite. On top of all this, these trucks promise more overall grind clearance with an improved "no hang-up" yoke. Guaranteed for life, these performance trucks are number-one for a reason.
For me: I can't stand not having kingpin clearance--and these Ind's have good clearance.
I was skating thunders before this, and I have found that the only Thunders that have good kingpin clearance are the 149mm II HI's. Every model of 147mm has no kingpin clearance. If you want 8.5 inch trucks, then I'd recommend Thunder 149mm, HI's, any model. But again, for some skaters kingpin clearance doesn't matter.
Some skaters think that the weight of the truck matters a great deal. While Thunders are lighter for than any Indy truck, I have not noticed a difference in my skating (even flip tricks). If you have a few extra bucks, however, you might as well get the Koston or Reynold hollow axel and hollow kingpin trucks. (NOTE: the Reynold's are exactly the same construction, geometrically, as these indy's under review; the Koston's are slightly lower in height).
Lastly, you will most likely want to replace the stock bushings with Bone's bushings. But it's a good idea to do this w/ almost every brand of truck.
Sick trucks, had some Royals before, these are definitely an improvement from those. Paired up with some bones medium bushings, these turn amazingly well and are super stable. I've had the nut from the kingpin fall out within 20 minutes, and about 2 weeks later it came off again. Luckily I had a tool the second time. Overall great trucks!
