Vehicle Fitment

• Nissan vehicles equipped with the SR20DE(T) engine (longitudinal mount) - exhaust (EX) side

Fitment Notes

• Engine-based fitment: compatible with any Nissan chassis running a longitudinally-mounted SR20DE(T), whether factory-fitted or swapped in

• Works with stock or aftermarket camshafts; optimal performance when paired with HKS camshafts set to recommended valve timing

Features

• Adjustable ±20° crank angle range for precise valve timing correction
• Scale markings at roughly 2° increments, with the center position matching stock timing
• Engraved "A" (Advance) and "R" (Retard) markers for clear, mistake-resistant adjustment
• Drive gear now pre-installed on the exhaust-side sprocket, eliminating the need to reuse or source the OEM gear
• Aluminum construction for reduced rotating mass
• Effective with a stock camshaft, with further gains available when matched to HKS cam profiles

Product Description

The HKS 22004-AN004 is a renewed version of HKS's long-running Slide Cam Sprocket for the SR20DE(T) engine, giving tuners precise control over exhaust-side valve timing. As camshaft profiles, duration, and overlap change with engine modifications, this sprocket lets you dial in the optimal timing angle rather than being locked to the factory setting, with a ±20° crank angle adjustment range and roughly 2° per scale marking for fine control.

The center marking matches stock timing, and clear "A" (Advance) and "R" (Retard) engravings help prevent setup errors during adjustment. This revision keeps the sprocket's proven design while adding a pre-installed drive gear on the exhaust side, so there's no need to reuse or separately source the OEM gear - simplifying both the purchase and the install. It works with a stock camshaft, but delivers its full benefit when paired with HKS camshafts set to their recommended valve timing.
