COMP Cams MJ58-2 MaxJet 0.058" Orifice Precision Carburetor Gasoline Jet - Qty 2

The COMP Cams MJ58-2 MaxJet Precision Carburetor Gasoline Jets deliver accurate, consistent fuel metering for carbureted performance engines. Featuring a 0.058-inch orifice and sold as a pair, these jets are a direct crossover replacement for Holley size 60 jets — engineered to eliminate the fuel delivery inconsistencies caused by conventional slot-type jets.

Standard flat-blade carburetor jets are notorious for sustaining damage during installation, which can alter fuel delivery by a significant margin. MaxJets solve this problem by using a 5/16-inch hex-stock brass body installed with a 5/16-inch nut driver, completely removing the risk of slot damage and ensuring precise, repeatable fuel delivery every time.

Key Features:

• Orifice Size: 0.058 inches (Holley equivalent: size 60)
• Thread Size: 1/4-32 UNF
• Material: Brass hex-stock construction — virtually indestructible
• Installation: Installs with a 5/16-inch nut driver — no flat-blade screwdriver needed
• Compatibility: Direct crossover from Holley jets; compatible with all known racing fuels
• Range: MaxJet gasoline jets available from 0.050 in. to 0.120 in. in 0.001-inch increments

COMP Cams MaxJet carburetor jets provide smooth and precise fuel delivery for street performance, drag racing, and circle track applications. Whether fine-tuning a naturally aspirated combination or dialing in a forced-induction build, MaxJets deliver the accuracy needed for consistent results on the dyno and at the track.
