Racing Aftermarket

Crafted and built for racing snowmobiles used in extreme environments – such as natural or artificially-made tracks consisting of tight turns, banked corners, steep jumps and obstacles.

The Dayco Racing RPX™ Belt – the Official Belt of the CSRA for Snowcross Racing – provides maximum performance under the most extreme snowcross racing conditions. This belt features precisely pre-formed cogs that enable optimal flexibility, cooler running and extended belt life, along with high twist cords that demand intense strength under extreme tension. Not only is it the belt of choice for many professional and amateur drivers, the Dayco Racing RPX Belt is also the strongest aramid belt available on the market today. Its softer specialized polymer compound allows for quicker upshifts and downshifts and the fastest hole shot, helping racers stay ahead of the competition.

Designed for use on Top Fuel dragsters and Funny Cars with supercharged nitromethane engines.

The Dayco 11mm blower belt is engineered with a hybrid carbon cord encapsulated in custom rubber compounds and patented low friction PTFE tooth fabric. This standard 11mm pitch, 84mm wide and 145 teeth belt was developed using real-world track data, specifically for supercharged nitromethane engines and built to withstand some of the highest dynamic loads in racing.

Designed and tested specifically for use on pro modified cars and top alcohol dragsters for professional racing purposes.

The Dayco 8mm blower belt features high strength Teflon-coated teeth for cogged drive pulleys and a carbon cord construction for extreme durability and performance on the street or track. Just like its 11mm blower belt predecessor, it was specifically engineered using real-world on-track data that enables it to withstand the rigors of 4,000 horsepower top alcohol dragsters and pro-modified race cars. It comes in multiple lengths and 50mm, 75mm and 84mm widths.

Engineered for and has been thoroughly tested for use on late model supercharged cars like ZR1 Corvettes, Shelby Mustangs and SRT Hellcat applications.

The Dayco Performance Supercharger Belt uses aramid fiber loaded EPDM construction, combined with high stiffness PET cords for extreme durability and reduced slip under high boost conditions. Belts are available in OEM sizing for many late-model, factory supercharged vehicles. This technology was developed with and tested by top level Drag Pak competitors using roots style superchargers.

The PowerBond race series brings the advantages of bonded balancers to high revving and high horsepower street/race applications where an SFI approved balancer is required. PowerBond Race Series balancers have been tested beyond 21,000 RPM without failure.

Designed for high performance supercharged engines.

• SFI 18.1 approved design
• Twin Key ways for secure crank mounting with six pulley bolt hole pattern
• High pressure bonded dampening runner for maximum torque resistance

For measuring a range of utility and industrial belts that measure up to 100″

Measuring all multi-ribbed belts, including competitive and OEM belts, the Dayco Factfinder® gauge III is meant for belts up 115″ in effective length for multi-rib belts and 100″ for V-belt lengths to indicate the corresponding Dayco replacement belt size.

Extends measurement of V-belts up to 130″ and multi-ribbed belt measurements up to 145″.
SKU 93863

Easily attaches to the Dayco Factfinder® gauge III for accurate measurement of larger V-belts and multi-ribbed belts and quick identification of corresponding Dayco replacement sizes.

For use in mounting Factfinder III gauges.
SKU 93871

These holding brackets allow the Dayco Factfinder® gauge lll to be mounted on a wall, counter or convenient location of your choice so that both hands can be free for more accurately measuring and verifying the exact size conventional V-belts or multi-rib belts needed.

Designed to measure a belt’s rib depth, rib profile and cracks.
SKU 047337

The aWEARness gauge helps technicians pinpoint wear on EPDM belts by measuring specific characteristics – like depth, profile and number of cracks. By placing the notched area lengthwise over the ribbed section of the belt, this pocket size device quickly and easily identifies the potential of serpentine belt failure. If there are more than four cracks per inch in the belt, technicians should replace the belt.

Dayco’s Hose and Tubing Cutter handles non-reinforced and textile reinforced rubber hose and tubing through 2″ I.D. A replaceable hardened stainless steel blade allows for a clear cut with no burrs or residue. Featuring a safe to use tough glass filled nylon handle with attached ring.
