For Use With 2004 And Later Gen Iii/ Ls Series Small Block, 200000Psi Tensile

from

$209.99
All Pro Series bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, and are rated at 200,000 PSI tensile strength. ARP Pro Series head bolt kits are application specific, designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP zero defect zero failure quality standard. Hardened and parallel ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12 point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more stretch to compensate for the additional compression of gaskets.

Product Features:
  • Pro Series Bolts Are Cold Forged To Ensure Molecular Integrity, Heat Treated Prior To Thread Rolling And Machining
  • Nominally Rated At 200,000 Psi Tensile Strength
  • These Fasteners Deliver Superior Strength And Meet The ARP Zero Defect Zero Failure Quality Standard

Mr. Gasket – Mls Head Gasket (Part No.3128G)

Mls Head Gasket

from

$114.99
Our unique Multi-Layered steel head gasket embossment formation process optimizes the embossment radius, reduces stress points, enhances gasket conformability, and provides uniform clamp load distribution. This all results in superior surface contact between block and cylinder head. All head gasket layers/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids. A typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket’s proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.

Product Features:
  • Gasket bore – 4.035 inch: Compressed thickness – .040 inch
  • Manufactured from 3-layer premium grade stainless steel and state of the art laser cutting
  • Optimized sealing embossments seals extreme cylinder pressure
  • Provides excellent stability and reduces cylinder bore distortion.
  • Proprietary polymer coating ensures the micro seal of engine coolant and oil fluids.
  • Ideal for supercharged, turbocharged, nitrous oxide and extreme compression ratio engines
  • For high-performance street, drag race and oval track use
