Ferrea PAC Alloy Dual Valve Springs for Toyota Supra 2JZ 2JZGE 2JZGTE

Ferrea PAC Alloy Dual Valve Springs for Toyota Supra 2JZ 2JZGE 2JZGTE

Our take

Ferrea's valve springs set the standard for aftermarket performance on the 2JZ cylinder head. The PAC Alloy dual valve spring kit is recommended for any 2JZ utilizing aftermarket camshafts and is our valve spring of choice for any high horsepower, high boost, high rev application.

This kit REQUIRES use of Ferrea Titanium Retainer #E11037 and BOTH Ferrea Spring Seat Locator #SL1001 and #SL1060. You can add the retainer kit and locators with the dropdown menu above. 

MANUFACTURER DESCRIPTION

Our springs are heat-treated and stress relieved, which dramatically increases the spring’s life. Our valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today’s aggressive valvetrain combinations.

We currently offer four different types of retainers to choose from: Titanium, Lightweight Tool Steel, Steel and Aluminum Magnesium retainers, all of which are CNC machined to perfection and offer superior strength and stability.

Ferrea takes great pride in offering premium quality Spring Seat Locators. Fully CNC machining in-house from 4140 chromoly alloy for different applications. Each piece is crafted to exact tolerances OD & ID specs and insure flat, parallel spring pad to the bottom surface. Heat treatment consists of a hard Nitrided surface for unmatched toughness and anti-wear characteristics.
