4.060″ BORE + .005″ RINGS SET 1.2MM 1.5MM 3.0MM, LOW TENSION

Description

Pro Steel ring sets
utilise a high strength alloy
steel top ring providing
superior bore conformity,
complimented by the
outstanding seal and wear
characteristics of a high
velocity plasma moly inlay
coating. Top ring weights are
under 10 grams, achievable as
a result of reduced ring
radials and short axial
heights helping to minimise
cylinder wall drag. Optional
2nd ring Napier hook profile
design help to improve oil
control and efficiency.
