Kyosho Ultima SB Dirt Master 2WD 1:10 EP Kit

Developed as a ‘neo-retro’ model, the “Dirtmaster” combines modern chassis design with traditional features. Breathtaking performance powers you over any low-grip surface from vacant lots to full-scale racing circuits. For your first Kyosho buggy, this is the one!


Superior surface tracing from the proven double-wishbone suspension system incorporates turnbuckle rods that allow length to be adjusted for efficient setting changes.

Resin oil-filled shocks absorb and reduce shocks from the road surface to maintain stable posture. With dial-adjustable spring tension, chassis height is easily changed. Compatible with competition-level springs.

Rear gear differential enables smooth cornering and is easy to assemble and maintain. For elevated performance on racing circuits, the ball differential for the Ultima series can be installed.

Slipper clutch is included as standard to protect the gears by allowing moderate slip when the drive system is under heavy load and allows adjustment of driving characteristics. Gear cover can also be installed to protect the gears from dirt and dust.

Full ball bearings that reduce drive loss equipped throughout the drive system.

Tapping screws are used to secure resin parts. Unlike entry-level models which use Phillips screws, the 2mm hex head screws make assembly and maintenance easier.
