1.400 TI Valve Spring Retainers - 10 Degree

The PAC Racing Springs 1.400 TI Valve Spring Retainers in 10-degree configuration deliver precision engineering for high-performance engine builds. These titanium retainers are purpose-built for applications requiring dual-spring setups with 1.090-inch and 0.695-inch outer diameter steps, offering the weight savings and strength characteristics critical to sustained RPM capability and valve control in competition and modified engines.

Titanium construction provides a significant advantage over traditional steel retainers by reducing rotational mass at the valve train. The 10-degree angle is engineered to work with corresponding valve spring geometry, ensuring proper seating and load distribution across the spring interface. PAC Racing Springs maintains strict tolerances on all retainer dimensions and step heights, which directly impacts spring seat pressure consistency and valve lash stability across temperature and load cycles. Each set contains 16 retainers—enough for a complete eight-cylinder engine.

Builders working with aggressive cam profiles, high-lift valve trains, or extended rev limits depend on PAC retainers to maintain valve seat control without compromising durability. The dual-spring capability allows tuners to dial in spring rates precisely, preventing coil bind while managing valve float at higher RPMs. Titanium's superior strength-to-weight ratio makes these retainers ideal for naturally aspirated engines, supercharged platforms, and drag racing applications where minimizing valve train inertia translates directly to power output and reliability.

PAC Racing Springs is recognized throughout the performance automotive industry for quality control and dimensional accuracy. These retainers integrate seamlessly into OEM and aftermarket cylinder head packages that specify 1.400-inch bore diameter with 10-degree taper. Verify spring seat compatibility and retainer bore size against your engine's specifications before ordering.
