HKS Step 2 Performance Exhaust Camshaft – RB26DETT | 280° Duration | Nissan Skyline GT-R R34 (BNR34)

Unlock higher RPM power from your R34 Skyline GT-R's RB26DETT with the HKS Step 2 Performance Exhaust Camshaft — a precision-ground performance camshaft engineered specifically for the RB26DETT in the Nissan Skyline GT-R R34 (BNR34). At 280° of duration, the HKS Step 2 exhaust cam delivers a more aggressive exhaust valve timing profile than the factory cam, extending the RB26DETT's power band higher into the RPM range for increased top-end power output. Sold as a single exhaust camshaft — intake camshaft sold separately.

⚠️ BNR34-Specific – Verify Before Ordering: This camshaft is engineered specifically for the Nissan Skyline GT-R R34 (BNR34) with the RB26DETT engine. RB26DETT camshaft specifications can vary between the R32 (BNR32), R33 (BCNR33), and R34 (BNR34) — verify that 2202-RN139 is the correct part number for your specific GT-R chassis before ordering.

Key Features

• Step 2 – HKS's Mid-Range Performance Cam Grind: HKS's Step 2 cam grind is positioned between the milder Step 1 and the more aggressive Step 3 in HKS's RB26 camshaft lineup — delivering a meaningful increase in performance over the factory cam and Step 1 while retaining more street drivability than the full Step 3 grind. An ideal choice for high-performance street and track BNR34 builds
• 280° Duration – Extended Exhaust Valve Timing: 280° of camshaft duration (vs the factory RB26DETT exhaust cam duration) extends exhaust valve opening duration — improving exhaust gas scavenging, increasing volumetric efficiency at higher RPM, and shifting the RB26DETT's power band higher into the rev range for increased top-end power output
• Exhaust Camshaft (EX) – Single Cam: This is the exhaust camshaft only — sold as a single camshaft. The matching HKS Step 2 intake camshaft for the BNR34 RB26DETT must be purchased separately. Verify whether your build requires exhaust cam only or both intake and exhaust cams
• RB26DETT BNR34 Specific: Precision-engineered for the RB26DETT as installed in the Nissan Skyline GT-R R34 (BNR34) — verify your specific GT-R chassis code before ordering. Not confirmed for BNR32 or BCNR33 without independent verification
• HKS Quality: Manufactured by HKS — one of Japan's most respected performance parts manufacturers with decades of RB26DETT engine development expertise across motorsport and street performance applications

Note: Exhaust camshaft only — intake camshaft sold separately. BNR34 specific — verify chassis code (BNR34 vs BNR32 vs BCNR33) before ordering. Performance camshaft installation requires valve timing verification and adjustment — professional engine building expertise is required. Additional supporting modifications (valve springs, retainers, ECU tuning) may be required depending on your specific build. A full engine tune is strongly recommended after installation.
