NexTek® Series
Valve Springs
Better By Design

Manufactured from “super clean”
Hi-Tensile Chrome
Silicon steel
Tip thickness designed to
eliminate overload breakage
Many part numbers available fully
polished or
Super Finished

Shot-peened to
MIL spec for maximum
fatigue life

Computer-aided modeling or designs minimizes
valve bounce and valve gear separation


  Nitro F/C Driver:
Jonnie Lindberg

Tightly controlled
open end flatness
reduces valve stem
side loading
Proprietary
multi-step heat
treating minimizes
load loss

Optimized “Select Size Fitting”
between outer and inner springs to maximize harmonic dampening and reduce heat generated during operation
Many offerings are a damperless design which eliminates unnecessary damper weight and reduces retainer wear

NexTek® Series
Lightweight Dual Drag Race Valve Springs

















• Higher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential
• Dual spring design reduces friction, which generates less heat and translates into greatly reduced load loss
• Extensively tested on the Spintron, dyno and race track (including blown nitro engines) and proven highly effective
• Smaller diameter, lightweight dual design allows engine to rev higher with improved valve train control
• Accepts smaller, lighter retainers which also promotes higher revs
• Ultra clean, high tensile strength chrome silicon material
• Super Finished multi-step surface enhancement significantly improves fatigue strength
• Ideal loads for multiple applications with minimal load loss
