BRIAN CROWER 16x Dual Valve Springs, Seats & Steel Retainers, Honda K20A K20Z K24, HIGH LIFT

Description

Brian Crower BC0040TS Dual Valve Spring Kit with Steel Retainers – Honda K20 / K24 (High Lift)

Unlock the full potential of your Honda K-Series race engine with the Brian Crower BC0040TS Performance Valve Spring Kit. Designed specifically for the Honda K20A, K20Z, and K24 platforms, this comprehensive valvetrain upgrade is engineered to handle the stress of high-horsepower, high-RPM, and forced induction applications.

The BC0040TS kit features PAC Racing dual valve springs, wound from the highest grade, super-clean chrome silicone alloy. These springs are processed with proprietary procedures to ensure consistent pressure and longevity, preventing valve float even under extreme conditions.

Unlike titanium setups designed strictly for lightweight racing needs, this kit utilises CNC-machined Steel Retainers. Steel retainers offer superior durability for high-mileage street and strip builds, ensuring your valvetrain remains reliable over time without the wear issues associated with titanium. Paired with steel spring seats, this kit provides the ultimate balance of performance and longevity.

Why Choose the BC0040TS Kit?

• High Lift Capability: Specifically matched for high-lift camshafts (such as the BC0047 Stage 2+ profiles), allowing for net cam lifts up to 0.620″ (15.74mm).
• RPM Stability: Dual spring design dampens harmonics and prevents valve float at extended RPMs.
• Durability: Steel retainers and seats are perfect for daily driven or endurance engines where longevity is key.

Important Installation Note:

• 2004+ Cylinder Heads: If you are installing this kit on a late-model cylinder head (manufactured after 2004), Honda changed the keeper groove angles. You may need to purchase BC2940 keepers (7° billet keepers) to ensure a proper fit with the BC retainers. Using stock keepers on late-model heads with this kit may cause component damage.
