Reverse Direction Transfer Case with Reverse Drive. Most diff gears are weak when competitors use large diameter tyres. Instead of reducing the axle speed at the diff, the Proformance Transfer case reduces the tails haft speed by up to 50%, allowing competitors to use much stronger diff ratios.

Mounting the Engine in the rear of a vehicle results in the trails hafts and differentials operating backwards. Running Diffs Upside down results in the Rear Diff running on the Coast Side of the Ring Gear, reducing the differential strength and reliability by up to 75% Instead of running the front and rear differentials "upside down", the Proformance Transfer Case reverses the direction of the drive allowing the Diffs to be operated in the correct rotation direction.

To change the Final Drive Ratio of a 4WD Race Car or Buggy requires the removal and reconfiguration of both the Front and Rear Differentials to replace the ring an pinions. Removal the diffs and rebuilding them with different ratios can take up to 16 hours. The Proformance Transfer Case is fitted with Quick Change Gears that allow the ratio between the Gearbox and Differentials to be changed in under 30 minutes. Ratios include 1:1, 1.22:1, 1.50:1 and 1.85:1

Under Drive Transfer Case for Off Road Racing and Rock Crawling.  Under Drive presents the need to run High Diff Ratios. High Diff Ratios have very small pinions and are not strong enough for Off Road Racing.  With a 20-40% under drive, competitors can run

To place an engine in the Rear of a 4X4 Race Truck or 4X4 Buggy, you must reverse the drive and be able to pass the rear Tail-Shaft past the engine. Proformance Motorsport Transfer Cases reverse the gearbox drive direction and allow the rear tails shaft to pass under the engine sump, connecting directly to the rear diff.
