It's not low drag gears you are looking for. What you are asking about are low drag wheel bearings and seals. Some people use REM or MicroBlue bearings with the low drag seals. They are a lot more pricey than the stock Timkin bearings and stock seals. You might check our dealers/manufactuerers section to see if they have them in stock. VMS Motorsports carries the REM bearings.
