  • Product description
  • CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt. CT-1 is specifically engineered to withstand the extreme conditions of today’s high performance engines. Professional engine builders enjoy a higher level of confidence with increased embedability, strength and durability.

    PROCESS

    CT-1 Dry Film Lubricant coating is applied as a spray process. Different surface preparation methods appropriate for the substrates will be used prior to the coating process. Coating thickness is varied to suit the application. Typical coating thickness for engine bearings is 0.00025” to 0.00030” inch (6 to 7.5 microns)

    ADVANTAGES

    Provides intermittent dry lubrication, not affected by dust or dirt, low coefficient of friction. Thin coating to accommodate assembly constraints, chemical resistance, corrosion protection, reduced friction and drag resulting in decreased parasitic losses.

    • Corrosion Protection
    • Increased Lubricity
    • Low Coefficient of Friction
    • Oil and Fuel Resistant

    EMBEDABILITY

    CT-1 coated bearings have excellent embedability characteristics, allowing debris contaminates to embed in the bearing, avoiding damage to the crank

    EXTREME OIL TEMPERATURES

    CT-1 coated bearings have shown a reduction in oil temperatures as much as 8°C - 11°C / 15˚F - 20˚F. Lower oil temperatures also aid in the loss of viscosity due to extreme heat.

    LOW OIL PRESSURE/OIL STARVATION

    Theoretically a crankshaft rides on a thin film of oil that protects both the crank and bearing. Real world experience such as cold starts and rough terrain conditions have proven otherwise. CT-1 coated engine bearings provide a dry film lubricant that protects against intermediate oil starvation

  • Brand
  • ACL ACL has a proud and remarkable history in motorsport.
    There is no better place to test its products than on a racing track. It is in competitions that good products shine!

    ACL Race Series bearings are today well-known products, but the foundation was already laid in 1960, when the manufacture of bearings for winning F1 cars took off. After that came series such as the Australian Supercar Championship and several others, where the development of ACL's products continued. The combination of history in motorsport, collected test data, new materials and processes means that the bearings are now a standard of what engine builders worldwide expect. 

    No matter what you are looking for bearings for, ACL is a safe way to go. IF you're looking for the best - demand the best.

57-3513 57-Series Air Intake Kit K&N Filters
K&N Filter 57-3513 57-Series Air Intake Kit K&N Filters
K&N 57 Series FIPK Air Intake Kits represent a dramatic performance improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded intake tubes that can reduce air temperature and decrease sound over a metal tube. Air flow restriction can exist between the air filter and engine reducing the benefits of a K&N performance air filter. K&N air intake kits virtually eliminate restriction in the air path by replacing the filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which in turn adds power.
