Why Use Darton Sleeves?

DARTON has been manufacturing precision performance sleeves since 1978. Currently Darton are the major suppliers of performance sleeves throughout the United States and Canada. The reason for this market share is simple, a very high quality product at the most competitive prices available. The ASTM specifications for performance ductile iron sleeves indicates a minimum tensile strength of 100,000 pounds. DARTON SLEEVES are much stronger than this and will withstand the punishment these sleeves must endure in Top Fuel motors. In addition, DARTON sleeve material is much more abrasion resistant and harder on the surface than any other product available. This feature provides for good oil retention, ring seal, and the ultimate in leak down performance. DARTON performance sleeves in a "Race Ready" condition are in stock for most all popular applications.
Darton pioneered modular sleeve designs and specialty ductile iron material beginning with their manufacture of top fuel sleeves in 1978. Darton sleeves excel in the harsh environment of all-out racing. Their centrifugally cast nodular composition represents the highest quality of any cast material. The unique matrix of Darton's centrifugally cast nodular iron sleeves provides unexcelled surface toughness. Darton's unique casting process provides a bore finish which, while very tough, promotes quick and total piston ring seal for the most complete combustion possible from each cylinder.

Darton now has engineered a superior solution to open-deck sleeve weakness by using a unique design which creates a solid deck of sleeve flanges held in tension, reinforcing the upper deck area and provides for in-field replacement with what they call “Modular Integrated Deck” (MID).

The Darton MID kits feature:

• Improved block integral strength
• Improved cooling
• "Wet sleeve" replace-ability
• Increased horsepower output potential
• Superior oil and compression control
• Street or strip application
• Kits can be installed by your local machine shop
• Full installation manual with every kit sale
• Superior cylinder sealing and ring wear
• Ductile iron w/130,000 psi tensile strength

Darton sleeve kits also come in a standard “flanged” design for blocks with a closed deck.

All sleeve installations are executed with CNC machinery , proper fixtures and factory authorized blueprinting procedures. Proper machining and installation are critical to this procedure.
Contact us about package pricing and our fast turn around service. We offer packages including machining installation and sleeves. If you have the sleeves send them with the block we can machine the block and install the sleeves.
