Power Slot Rotors

Power Slot rotors are 1-piece, slotted, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Launched in 1998, Power Slot was the first premium slotted replacement rotor program in North America. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Power Slot covers more than 2500 applications, all machined in Power Slot's California manufacturing center. Every Power Slot rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

Most Power Slot rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Power Slot has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

Power Slot rotors feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction, or "bite", amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.

Every Power Slot rotor is finished with a black e-coating on both sides of the hat, inside the cooling vanes and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral runout issues.

Power Slot rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

Power Slot rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

Power Slot brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

Power Alloy metallurgy is another unique feature in many of Power Slot's rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Power Slot's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Power Slot's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).

They match the OEM ones!
They are just as good as the OEM caps and fit perfectly. I found if you put a small piece of rubber with adhesive on 3 of the tabs they hold better. I did it on all of them including the oem.

Good buy and good replacement for stock
I can’t keep these on my UTV, so it’s good to find a reasonably priced alternative.

Definitely keeps your hands warm !!
Color: Black
These fit nicely on a H.D. Road King. If you bike has heated grips you can drive in 30 deg F weather with only a thin pair of leather gloves. Update: They kept our hands toasty with the heaters on Level 2 and just wearing a thin pair of leather gloves (for grip) while riding in temps down in the low 30's, high 20's. I would definitely recommend these... the photo in the ad is pretty indicative of how they fit on handlebars. They're really designed for ATV's that have no turn signal lamps on the handlebars. Without modification, they do cover the handlebar mounted turn signals on a Sportster, but not on a Roadking. The draw string that seals the mittens around the handlebar could have a more positive grip to stay closed... we wound up double tying it around bar and that works great. The thing we like most aside from how warm they are (the lining feels great)... is that the cuffs are fairly rigid and don't collapse when you take you hands out (like the photo) which makes it super easy to pull you hands out and put 'em back in again. That's really important at a stop light, but even more important when flying down the road at highway speeds... you just can't afford to be fooling around trying to thread your hands and a coat sleeve back into mittens that are limp and flop down closed when you take you hands out... I hope this help... be safe !!
