MIP Rollers D413 drive system
Coming from MIP and made for the HB D413 4WD buggy is the all-new Rollers drive system. Based on the design ideas of the rebuildable Pucks system for 2WD buggies the Rollers offer better wear characteristics for demanding applications such as 4WD buggies while being completely rebuildable at the same time. The design revolves around replaceable tubes that offer a larger surface than conventional pins and due to their softer material they are also less harsh on the outdrives as they wear faster than the steel parts while being much cheaper to replace than a full driveshaft. The sets are available for the front and the rear of the D413 and they include new shiny driveshafts, the rollers and new steel outdrives.
