MEG202103
Mega long exhaust springs (3.3 x 80mm, MEG202103) for Mega ZX12 and ZX15 DSII+ nitro engines, crafted from high-tensile stainless steel to securely fasten tuned pipes and headers under extreme heat and vibration. Will fit most small block engines.
Keep your tuned pipe locked tight with the genuine Mega ZX12-15 Long Exhaust Spring (3.3 x 80mm, MEG202103), engineered specifically for Serpent Mega ZX12 and ZX15 DSII+ 2.1cc/2.5cc nitro engines in high-vibration 1/10-scale racing. Premium steel with high coil tension, these 80mm springs provide superior pull strength to maintain header-to-manifold and pipe-to-header seals across full-throttle heat cycles and rough-track abuse. The extended length ensures proper reach on long-header setups while preventing exhaust leaks that sap power or cause tuning instability. Easy hook-and-loop installation during pipe swaps or maintenance. Essential for off-road durability and on-road consistency; stock up to eliminate mid-race pipe drops and keep your Mega powerplant screaming to the finish.
