Best Engine Internals & Accessories for 2013-2017 Holden VF Commodore

The VF Commodore's LS-family engines — L77, LS3, or LSA — are well-served by the aftermarket, but fitment specifics matter more than most people expect in this category. A harmonic balancer that clears the timing cover on an LS1 won't necessarily drop straight onto an LS3 snout. Rear main seals vary between block revisions in ways that aren't always obvious from a part number alone. Cross-referencing GM part numbers is worth the extra few minutes. Proflow's LS-series lineup is a solid benchmark — their camshaft retainer thrust plate carries the OEM GM reference alongside their own SKU, which makes verification straightforward. For sealing components — timing cover gaskets, rear main seals, freeze plug kits — scrutinise seal material quality, not just price. Rubber compound durability matters on a daily-driven VF that sees real temperature cycles. Billet hardware in a freeze plug kit is worth the premium over pressed-in brass if the block is going together once and staying that way. Know your exact engine code before you order. Check whether the part suits your specific variant. Don't assume VE and VF fitment is interchangeable just because the engine family looks the same on paper.
