KIBBLEWHITE Valve Spring Kit 60-1006

Factory valve springs are engineered for longevity under normal driving conditions, not sustained high-RPM performance. If you're building a boosted engine, running aggressive cams, or pushing higher valve lift, stock springs will fail—costing you reliability and power. The KIBBLEWHITE 60-1006 kit delivers the spring rate and durability needed to keep your valvetrain intact under extreme conditions.

This complete valve spring replacement uses CrSi (chromium-silicon) alloy construction for superior fatigue resistance and higher load capacity than OEM springs. Paired with hardened steel base washers and titanium retainers, every component is optimized to reduce mass while increasing durability—critical for engines running elevated boost, nitrous, or extended RPM ranges.
