ProTek RC 0.63" 1/8 Exhaust Manifold Spring (3) (Short) - PTK-7101

🏁 ProTek R/C Short Exhaust Manifold Springs (15.8mm)

High-Temperature Short Manifold Springs for 1/8 Nitro

This is a set of three ProTek R/C 0.63" (5/8") Short Exhaust Manifold Springs, designed for 1/8 scale nitro engines. These springs secure the tuned pipe to the tuned pipe manifold—an essential connection that must withstand extreme vibration and prolonged engine heat.

During normal use, manifold springs gradually lose tension due to heat cycling and vibration. When springs weaken, they can loosen, which may cause exhaust leaks, blown gaskets, or performance loss. Replacing worn springs with ProTek’s high-quality short springs helps maintain a tight, reliable seal for consistent power and engine protection.
