■Features

• The long-selling “Slide Cam Sprocket”, highly regarded among SR20DE(T) users, has been renewed.
• As engine tuning progresses, such as changes in camshaft profiles or engine specifications, the optimal valve timing also changes. This product allows adjustment of cam timing to match changes such as increased duration on the intake and exhaust sides and the resulting overlap, enabling more precise valve timing settings.
• The adjustment range is ±20° (crank angle) from stock, and each scale mark on the inner plate corresponds to approximately 2° of crank angle.
• The center position is designed to match the same phase as the OEM pulley. To help prevent adjustment errors, “A” (Advance) and “R” (Retard) markings are engraved for easy visual reference.
• This product is effective even when used with a stock camshaft, but greater performance gains can be achieved when used in combination with HKS camshafts and set to the recommended valve timing.
• While maintaining its proven functionality, the EX-side sprocket is now sold with a pre-pressed drive gear. There is no need to transfer the gear from the OEM sprocket or source a new one, making the product more accessible and easier to install.
