4 inch (105mm) State of the art PPG and PPC exhaust springs


Size from hook to hook: 4 inches (105mm)

Material: Stainless steel

Maximum stretch: 5 inches

These are state of the art PPG and PPC exhaust springs!

Are you tired of exhaust springs that constantly break causing damage to your propeller? Well we were. Nothing worse than a nice carbon prop getting dinged up by a broken exhaust spring! They say the definition of insanity is doing the same thing over and over expecting different results. Here is your chance to break the cycle and buy quality springs that are designed for our kind of aircraft!

These springs have been designed specifically for the incredible high temperatures of PPG and PPC exhausts.. They are great for 4 cycle motors too! The unique “dual swivel” design and stainless steel construction allow the hooks to freely swivel inside of the springs preventing metal fatigue that so often results in breakage.

These springs are not off the shelf- you can’t buy them anywhere but here. They were designed by the owner of Blue Sky PPG and tested thoroughly to ensure you get the highest quality product.

  • Model: 4" PPG exhaust springs
