New bulletproof transfer case option for Mitsubishi Evo

The OEM gears in the Evo transfer cases are fine for stock applications, but are prone to pitting, galling and shearing in high torque applications and particularly in sustained motorsport use. This shows up as the characteristic “death whine”.

IMG_8559Finally, we have a real solution to this problem.

Together with Brena Corse, we can now offer transfer case crown wheel and pinion options that are of unbelievable quality and durability. These are made in Italy on the best machines possible, by a maker who has supplied to Group A factory rally teams, and OEM supplier to Ferrari and Bugatti.

Due to the setup procedures required for the unique Brena gear profile, we are unable to offer the transfer case crown wheel and pinion sets as a stand alone item for sale. They must be installed by us at Neat Gearboxes (Adelaide, South Australia) to ensure correct fitment – you can contact us here.

What you get:

  • transfer case stripped and inspected
  • chemical clean components
  • bead blast housings
  • new Brena Corse crown wheel and pinion (choices below)
  • new pinion bearings
  • new pinion lock nut
  • new carrier bearings
  • new seals and O rings
  • Dimple magnetic drain plug
  • ACD clutches inspected and pistons pressure tested
  • assembled to custom specifications to ensure reliable running in extreme applications
  • 700ml NEO RHD 75w90 gear oil (recommended fill for F1, extreme motorsport use)

Suitable for:

Evo 4-6; Evo 7-9; and Evo X

Price (in Australian dollars, includes GST – international customers will save 10%):

ISF option $3,590

Isotropic Super-Finishing (ISF) improves surface finish and reduces oil temperatures. An excellent option for a tough street car, or sprint/time-attack where the runs are not especially long (where oil temperatures are not likely to spike). 800Nm capacity.

Carbon Lafer option $3,990

Carbon Lafer leaves a diamond-like carbon deposit on the surface of the gears, leading to incredibly durable gears even in low oil situations and in extreme temperature situations. Cutting edge technology. Recommended for sustained circuit and rally competition use, or where temperatures are very high. 800Nm capacity.

Drag race option $4,090

The drag race spec gears are made of a special steel used extensively in F1. The key advantage is that the teeth will not break with loads up to, and beyond 1000Nm.
