Evo 123 - Carrillo - 4G63 Pro-A Connecting Rods (3/8 WMC Bolt) - 6-Bolt
Carrillo Pro-A connecting rods, 3/8 WMC bolt — 6-bolt 4G63
The lightest of Carrillo's three beam profiles, and the specialist choice of the group. Where the Pro-H prioritises maximum load capacity, the Pro-A's A-beam trims reciprocating weight as far as the design sensibly allows — the right trade when a 4G63 build is aimed at revs and response rather than at the absolute ceiling of cylinder pressure. Fitted with the standard 3/8 WMC fastener. If you are unsure which way to go, the Pro-H is the safer default; take the Pro-A when your builder has told you low rotating mass is the objective. Set of four.
- Beam: Pro-A (A-beam) — the lightest beam in the Carrillo range, favouring low rotating mass and RPM response
- Fastener: 3/8 WMC (H11 tool steel) bolt, roughly 220,000 psi ultimate tensile strength, suited to builds in the 800+ wheel-horsepower range
- Carrilloy chrome-nickel-moly-vanadium VAR alloy, mar-aged heat treated, forged and fully machined
- 5.906 in center-to-center length, 21mm full-floating wrist pin
- Supplied as a set of four rods
Fits:
- Mitsubishi Lancer Evolution I (CD9A, 1992–1994)
- Mitsubishi Lancer Evolution II (CE9A, 1994–1995)
- Mitsubishi Lancer Evolution III (CE9A, 1995–1996)
Specified for the 6-bolt 4G63 short block and its 21mm wrist pin, a frequent swap in early Evo builds — not the factory 7-bolt engine. Double-check what is on your stand before ordering.
