STRC SC10 & Blitz universal driveshafts

More new products from ST Racing Concepts with the release of these heat treated carbon steel universal driveshaft sets for the Associated SC10/T4, HPI Blitz and Universal Bones for OFNA Hyper 10SC. Universal driveshafts are typically an important and often the first upgrade for many racers and bashers, but for years manufactures have left their design and material of universal driveshafts to be relatively the same despite the the change to the more powerful LiPo battery/brushless combination. STRC inspected all components of the traditional universals driveshaft and aimed to improve in material and design. The material is critical and equally important is the heat treatment process. After months and months of prototype testing in different material and increments of heat treating, they believe they have
developed a better finished product of this ‘standard’ upgrade.

For their design, they increased the diameter of the universal driveshaft bone for more durability against the increased power, the heavier weight of short course truck and larger diameter of short course truck tires. They also used the same carbon steel material for axles, which features two sets of universal pin holes so you can get twice the life out of the same set of axles. The universal joints and joint pins are made from a carbon steel material as well and the pins features a “step” for the setscrew to have a flat spot to more securely hold the universal driveshafts together. Lastly, even the universal shaft roll pin at the end was not over looked. Carbon steel at the pin although strong will unfortunately add excessive wear to the diff outdrives, thus a different material was selected just for the shaft pin for durability and ease of wear on the diff outdrives. Available for the popular Associated SC10 and HPI Blitz RTR. They also used the same carbon steel material for the Hyper 10SC universal driveshafts as the kit universal material have long been a problem for Hyper 10SC owners. Expect Slash 2WD universal kits soon.
