Low Drag Hub Components

Adjustable Bearing Spacers

Covered by US Patent # 6,312,162, DRP adjustable bearing spacers eliminate excessive bearing preload leading to significantly reduced drag, lower bearing temperatures, longer bearing life, reduced maintenance and most importantly, higher performance.  All DRP Bearing Spacers are manufactured in our USA facility.

Low Drag Bearing Kits

We take top quality hub bearings and put them through a specially designed process including REM Super finishing to produce the lowest drag bearings we've tested.  Some bearings are good under low loads.  DRP Low Drag Bearing kits offer low drag, low temperatures and longer life under high thurst loads, such as short track cornering forces.

Ultra Low Drag Hub Seals

DRP ULD hub seals are custom, US made, designed for racing hub seals.  These seals are ultra light weight, with aluminum housings and ultra low drag, with full PTFE elements.

Ultra Low Drag Bearing Grease

DRP ULD hub beearing grease is a specially formulated, high speed bearing grease manufactured by Kluber Lubrication.  We've tested all major bearing greases and have not found any commerically available grease to come close.
