For those who must have the ultimate in technology and performance for their racing machine, RCE offers these silicon nitride ceramic ball bearings with lower friction, less inertia, cooler operating temperature with less wear than conventional steel bearings. Their durability is unsurpassed. The reduced operating temperature will help keep your cases and intake charge cool and dense, especially towards the end of that key race, when you most need it. Micro-welding, which is common in standard steel/steel bearings is eliminated with this ceramic ball/steel race bearing. Our testing shows 1/2 to 5/8 HP improvement. Not a ton, but how important is that critical 1-2 kart length lead at the end of the straight? How do we do this? By precision matching sets of silicon nitride balls that weigh 60% less than the conventional steel balls they replace, the RCE main bearings are assembled with a high temperature, low friction thermoplastic cage with less friction than the standard steel cage. Long used in high tech applications such as racing turbochargers, F1 wheel bearings and high speed milling machines, RCE brings their well documented advantages to you for your CR, YZ, and KX crankshaft. For the price of a single set of tires, you can have a power advantage over the competition all season! How long do they last? We've had sets in several engines for over 2 long track seasons for over 30 hours! A good general rule is to change Hyper spin main bearings every other crank replacement. Installation exactly the same as standard bearing, since the races are OEM steel. Teach your competition a lesson in technology! Less friction....Cooler Running......Longer Lasting....... Less Inertia.....More HP! No wonder they've been winning many big races in Super-Pro, S1 and K1 as well as long track racing. Price is per bearing (each)
