We at PAR understand that supporting our Products and Customers is extremely important. This is why PAR provides a full parts replacement or repair 12 month warranty for any manufacturing, workmanship or quality issue for all of our gear set and drive train products for that extra peace of mind.

A warranty claim applies if the transmission component is proved to be defective as a result of material or manufacture fault. Having said this, PAR will not design and manufacture a components if it will fail.  Also covered by the same warranty are any custom gear sets or ratios.

Any parts being returned for warranty must be shipped back by the buyer as packed/shipped  when purchased. PAR will not cover any costs related to transmission removal/refit or consumables.

Customer claims against the seller are excluded if assembly is incorrect, OEM component failure was the cause and sub standard lubrication is used. The correct lubrication and maintenance interval is mandatory to receive the full 12 month warranty. With the high performance gear sets, contact ratios are reduced with the aggressive tooth profiles required for gear strength, hence in turn this introduces incredible stress and loads onto the transmission’s gear oil. The only grade gear oil recommended by PAR is a full synthetic SAE GL5 or GL6 for all transmissions with a recommended change interval of 5000km. Failure to comply with these recommendations can result in accelerated gear wear and breakage which will not be covered under warranty.

Warranty is only offered to the original buyer.


Some recommended gear lubricants are:

  • NEO Synthetic 75W-90HD
  • NEO Synthetic 75W-90RHD (highly recommended for circuit racing and prolonged high temperature applications)
  • Penrite Pro Gear 75W-90 GL5-6
  • Motul Gear 300 75W-90
  • Motul Gear Competition (recommended for circuit racing and prolonged high temperature applications)
