Product Description

The Brian Crower BC0088S Spring/Retainer Kit is a purpose-built, race-only valve train upgrade for performance-oriented builds using the Honda L15B7 1.5 L turbo engine. Designed to deliver stable valve control at high RPM, the kit features premium chrome silicone alloy springs matched with CNC-precision steel retainers and keepers. Each component is engineered to uphold ideal seat and open pressures through extended use, reducing valve float and enabling the use of aggressive cam profiles.

Specifically validated for 2016-2021 Honda Civic 1.5T and 2017-2021 Civic Si platforms, the BC0088S kit supports a net cam lift of 0.490" (12.45 mm). The spring specifications - 2.231" free length, 1.975" seat/58 lbs, 1.500" open/154 lbs, and 1.320" coil bind - ensure reliable performance under racing conditions. Please note: this is a **race-only product**, not legal for street-driven vehicles.

Fitment is confirmed through 2021; coverage for 2022-2025 models is currently unconfirmed. Builders should cross-check compatibility, especially for FWD setups and Civic Si variants. Installation requires standard valve train disassembly and reassembly procedures - ensure proper degreasing, lubrication, and torque specs. This kit is ideal for enthusiasts and racers upgrading camshafts and seeking improved lift capacity and valve stability.
