Genuine HT spare/option part.

These heavy duty differential drive cups for front or rear differential in a Losi 5ive-T/B or MINI WRC are made of 300M / Böhler V132 steel and are characterized not only by high hardness, but also simultaneously toughness. The service life is therefore much higher than for the stock cups.

300M steel is used in motorsport and aviation for high strength parts. As a highly pure material, it is significantly more expensive than conventional steels, its high basic strength and toughness make the machining a time-consuming task.

The shape of these drive cups now allows the use of driveshaft boots and grease lubrication, which increases service life enormously. In addition, these HD drive cups have two sets of slots for the pin of the drive shaft, this means another doubling of the service life.

We recommend y0809 Klüber grease for lubrication of closed HD drive cups.
A dry run like with stock parts is theoretically possible, but absolutely not recommended because it would waive the enormous advantage of encapsulated lubrication and the associated wear reduction.

The set for the rear includes modified stock alloy bearing carriers, which provide improved clearance for the driveshaft boots.

You can find advices for installation at the specifications-tab.

Contents:

• Front set:
• 2 pieces of 300M steel HD differential drive cup, front and rear application
• 2 pieces of driveshaft boots
• Rear set:
  • 2 pieces of 300M steel HD differential drive cup, front and rear application
  • 1 pair of modified bearing carriers
  • 2 pieces of driveshaft boots
  
  
  

The cylindrical section of the driveshaft boots must be trimmed down to a remaining length of approximately 14 mm. When installed the boot will then end about one millimeter before the cone on the drive cup. This ensures reliable fit without rubbing against the modified bearing carriers in the rear axle.

Axle boots are subject to wear. They should therefore be checked regularly and replaced if damaged. Only undamaged boots protect the lubricant against contamination and thus ensure significantly reduced wear.

Running the drive cups without lubrication as with the stock parts must be avoided in any case, since this would increase wear enormously.
