Liner Set (4) Ductile Iron 85mm Ultimate Strength
[2085LDI]
$825.00 $645.00

CENTRIFICALLY CAST DUCTILE IRON liners are a must for turbo and high compression normally aspirated engines. Rings stay sealed better when the bore concentricity is maintained and horsepower is improved especially at high RPM.

Still cast OEM and gray iron liners are not nearly as strong or resiliant as centrifugally cast ductile iron. This complex alloy (100-RC32) has greater:

  • Hardness (resistance to wear).  Brinell 277 (Gray Iron 225 OEM 143) 
  • Tinsel strength (resistance to cracking).  113,100 psi (Gray Iron 35000 OEM 27000 psi))
  • Yield Strength (before it deforms) 83000 PSI (Gray Iron and OEM N/A)
  • Elasticity (recovers from bulging under load & rebounds to round shape)  5% (Gray Iron N/A)
