Ferrea Valve Spring Kit Nissan RB26 -Dual Valve Spring /Retainers/Spring Seats/Locks

Engineered for high-performance enthusiasts, the Ferrea 110lbs Dual Valve Springs and Titanium Retainers Kit is designed to match the exceptional standards of Nissan's legendary Skyline GT-R models. Crafted from premium-grade alloy and treated with advanced thermal processes, these valve springs ensure optimal load and stress distribution even in the most demanding racing conditions.

Ferrea's cutting-edge spring design and material selection make these springs ideal for high-revving applications, providing your engine with the confidence to race at peak performance without concerns of part failure, valve float, or coil bind. Whether you're restoring your engine or setting up a full race-spec build, Ferrea components enable higher revs and more aggressive cam profiles with ease.

Ferrea is renowned in the industry for its superior quality and reliability. A quick internet search reveals a consensus of praise for their products, despite not being the cheapest option available. When it comes to top-tier valvetrain components, Ferrea stands unrivaled.

Three common issues with stock valvetrain systems are effectively mitigated with Ferrea's superior components:

• Binding: Stock springs can seize and lose their ability to manage valve operations, potentially causing further engine damage. Ferrea springs are designed to avoid this issue.

• Breaking: Inferior springs may shatter and drop valves into the combustion chamber, devastating the engine’s bottom end. Ferrea’s robust construction prevents such catastrophes.

• Valve Float: Stock springs may fail to close valves fast enough at high RPMs, resulting in power loss due to escaping combustion gases. Ferrea springs ensure full valve closure on every cycle, maintaining engine power.

Each valve spring is heat-treated and stress-relieved, significantly extending its lifespan. They provide the stability necessary for high-lift, high-RPM engines while minimizing load loss, perfect for today’s aggressive valvetrain setups.

In addition to the springs, Ferrea offers four meticulously machined retainer types: Titanium, Lightweight Tool Steel, Steel, and Aluminum Magnesium. These retainers, crafted with CNC precision, deliver exceptional strength and stability, ensuring your valvetrain's reliability.

Ferrea's Spring Seat Locators are machined in-house from 4140 chromoly alloy, providing perfect dimensional accuracy and a hardened nitrided surface for unparalleled toughness and wear resistance. Each seat locator ensures a flat, parallel spring pad surface to maintain optimal performance under extreme conditions.
