BLOX Racing valve springs are wound using super clean, chrome silicone alloy. These valve springs are designed and engineered for both high performance street driving and all-out racing conditions.

Each set provides maximum lift while preventing valve float and helps counter the effects of spring surge. These are perfect for naturally-aspirated and forced-induction engines.

Easy installation, no machining is required. Highly recommended for aftermarket, performance camshafts.

For maximum results, use with BLOX Racing Ti retainers and high compression valves.
