Why ViperTac Recommends ASG Springs Over SHS

There are springs—and then there are performance springs.

SHS Springs are solid, dependable options made from standard steel, offering a 1:1 compression ratio. This means the motor must use the same amount of energy to compress and release the spring, placing greater strain on the motor and gears.

In contrast, ASG Ultimate Springs are crafted from advanced SiCr (Silicon-Chromium) steel, offering superior tensile strength and elasticity. These springs feature a 1:3 compression ratio, meaning the spring requires only one unit of energy to compress but delivers three times more output energy on the forward stroke.

This advanced engineering results in:

• Reduced wear on your motor and gears

• Improved efficiency and firing consistency

• Lighter, more responsive spring action

Key Features

• SiCr spring steel construction – Lightweight, durable, and high-tensile for consistent performance

• 1:3 compression ratio – Delivers more power output with less effort from your motor

• Closed & ground ends – Prevents bending and ensures smooth, stable cycling

• Color-coded ends – Quick and easy power identification between setups
