Best Engine Internals & Accessories for 2006-2013 Holden VE Commodore

The VE Commodore's LS-family engines — L98, L76, LS2, LS3, or the supercharged LSA — share a solid bottom end architecture that responds well to quality internal hardware, but they're not without their quirks. Timing cover gaskets harden and weep with age, rear main seals are a known service item on higher-mileage examples, and the factory harmonic balancer is worth replacing on any engine that's been modified or is showing its years. When shopping this category, pay close attention to whether parts are spec'd for Gen III versus Gen IV block — the LS2 differs from the L76, L98, and LS3 in ways that matter for camshaft retainer plates and freeze plug sizing. Proflow is a reliable go-to for LS sealing and hardware in the Australian market. Their billet freeze plug kits and moulded O-ring cam retainer sets are well regarded for engines being freshened or built from scratch. For balancers, match the correct snout diameter and reluctor ring tooth count if your car runs a drive-by-wire tune. Cheap offshore parts can look the part but cause headaches — a rear main seal that doesn't seat cleanly or a balancer with runout issues will cost you far more in labour than the few dollars saved upfront.
