Key Features & Benefits – Cat Cams LADA Valve Spring Set GOLD

The Cat Cams LADA Valve Spring Set GOLD is a dual setup with an outer and inner spring pair. It is listed for Lada 2101–2107 and Lada VFTS.

The gold coating targets added corrosion protection and durability, while the dual spring layout supports valve control under higher loads. It is not compatible with stock retainers, so retainer/seat selection and installed height checks are part of the install.

When is this useful?

Useful in motorsport and tuned builds running higher RPM or increased valvetrain demands. It also helps when you want to match spring load to your specific installed height rather than relying on a stock setup.

Selection & installation tips

• Installed height: measure installed spring length with your chosen retainers/locks, then compare it to the free length.
• Coil bind margin: check total compression at max valve lift and keep margin before the solid length.
• Retainer & seat fit: confirm seating surfaces match 28.6 mm (outer) and 21.3 mm (inner) diameters.
• Spring load target: use the listed length → force points to compare against your cam profile and RPM goal.
• Clearances at full lift: verify retainer, seal, and guide clearance through the full lift range.

Before final assembly, verify installed height, retainer/seat geometry, and maximum valve lift. Compare your measurements to the dimensions and the length–force points listed above.
