The GSC Power Division range listed here covers:

S1 Billet Camshafts – milder profiles aimed at increased mid-range torque and top-end power without sacrificing idle quality.
S2 Billet Camshafts – a step up for higher-output builds, with a focus on the mid-to-high RPM range.
S3 Billet Camshafts – dedicated racing profiles for high-horsepower builds running large-frame turbochargers.
R2 and R3 Billet Camshafts – race-oriented profiles listed for Ford 5.0L Coyote applications, including options for ported heads.
Valve Springs – beehive and single spring designs offering harmonic control and seat pressure in a compact footprint.
Titanium Retainers – conical, cylindrical, beehive and dual-spring retainers, available individually and in sets.
Valve Guides and Balance Shafts – including stopper-style intake and exhaust guides and race balance shafts.

Choosing the Right Part

GSC parts are engine and cylinder-head specific, so match the listing to your engine code rather than the model year alone. Applications listed in this collection include Subaru EJ255/EJ257 (WRX and STI), Subaru EZ30 Phase 2, Subaru/Toyota FA20 (BRZ/86), Mitsubishi 4G63 and 4G63T (Evo 1–9), Toyota 3S-GTE and 2JZ, Nissan VR38DETT, Honda B-Series VTEC, Toyota/BMW B58, BMW S58 (M3/M4 2021+), Ford 5.0L Coyote and the Audi/Lamborghini 5.2L V10.

When comparing camshafts, check the duration figures in the product title (for example 282/282, 292/300 or 268/270), whether AVCS or an intake trigger is required, and whether the listing is a complete set or a single shaft. Valve spring and retainer listings often specify a matched kit or spring code — such as retainers for the GSC5756 or GSC5056 kits, or for the TVS1850 spring — so confirm the spring and retainer are intended to work together. Retainer and guide sets are sold in fixed quantities (sets of 12, 16, 24 or 40), so check the count suits your cylinder head.

Installation & What You'll Need

Camshaft and valvetrain replacement requires cylinder head disassembly, correct valve timing and accurate measurement of installed height and valve-to-piston clearance. Installation by a qualified professional workshop is strongly recommended.

Depending on the job you may also need valve spring compressors, replacement valve stem seals and head gaskets, appropriate collets or keepers to suit the retainer style, a degree wheel and dial indicator for cam timing, and an engine tune to suit the new camshaft profile. More aggressive S2, S3, R2 and R3 profiles generally require upgraded valve springs and retainers rather than factory hardware.

FAQ

Do I need to upgrade my valve springs with GSC cams?

For S1 profiles, factory springs can sometimes be retained depending on the chassis, but for S2 and S3 camshafts a high-quality valve spring and retainer kit is mandatory. The higher lift and aggressive ramp rates require the increased seat pressure and stability of an upgraded spring to prevent valve float at high RPM.

What is the benefit of a beehive valve spring?

Beehive springs feature a smaller diameter at the top, which allows for a lighter titanium retainer. This reduces overall valvetrain mass, improving harmonic stability and allowing the engine to rev more safely and efficiently compared with traditional dual-spring setups.

What is the difference between S1, S2 and S3 camshafts?

S1 profiles prioritise mid-range torque and street driveability with minimal impact on idle quality. S2 profiles move the power band higher for stronger mid-to-high RPM output, while S3 profiles are dedicated racing grinds intended for high-horsepower builds running large-frame turbochargers.
