SPECIALIST
Leading A-Series engine specialist since 1981
IWIS is world renowned for producing the highest quality timing chains, which are used in all forms of motorsport applications.
There may be cheaper chains on the market, but these often stretch prematurely, so we always insist on the best.
The race simplex chain is specifically for our Race Simplex Vernier setup and cannot be fitted to a standard engine.
Duplex is compatible with both the Steel/Alloy MED Vernier and All-alloy MED Vernier and others on the market.
