These pushrods are machined in Erson's own Nevada plant to their own
strict specifications. Erson uses only the best special-mill run, 4130
hard-drawn steel tubing. Other, cheaper materials are available.
However, only aircraft-grade 4130 alloy delivers the strength and
durability to withstand the higher valve-spring pressure and RPM
generated by today's high performance and racing engines.
