Supertech Nissan CA18DET 16V Dual Valve Spring Kit

The dual spring design in this Supertech kit is built to handle higher RPMs and more aggressive camshaft profiles common in modified CA18DET engines. Each spring is made from a high-tensile chrome-silicon wire, a material known for its strength and ability to withstand repeated stress without losing its tension. This means your engine's valves will close reliably, even when you're pushing the engine hard.

This kit includes everything you need to replace your stock valve springs. You'll get the dual springs themselves, which offer increased stability over single springs, helping to prevent valve float at high engine speeds. The kit also comes with the necessary retainers and locks, all manufactured to Supertech's well-built standards. Proper installation is key here; ensure you follow the manufacturer's guidelines for spring seat pressures and valve lift to get the most out of this setup and protect your engine.

When you're rebuilding the top end of your Nissan CA18DET, especially if you're upgrading to a more aggressive camshaft or planning on higher revs, a strong dual valve spring kit like this one is essential. It's designed to work with the specific dimensions of the CA18DET cylinder head, ensuring a direct fit and reliable performance. This kit is a solid option for anyone serious about getting the most out of their engine build.
