Does this shell fit both the VIKING 3350 and VIKING 2450?
Yes — the KP4577-2 fits 5th generation versions of both the VIKING 3350 and VIKING 2450 series. Confirm your helmet's 5th generation designation before ordering — shell generations are not interchangeable.
Is the auto-darkening filter included?
No. This is the outer shell only. Your existing ADF from your current 5th gen VIKING transfers to the new shell. The shell replacement preserves your electronics investment.
Is there a complete Code Red helmet available?
Yes — the Lincoln VIKING 3350 ADV Code Red Helmet (K4034-5) is the complete helmet with Code Red graphics.
What other 5th gen replacement shells are available?
WeldingMart carries Steampunk (KP4574-2), Daredevil (KP4576-2), and Hot Rodders (KP4580-2) — all direct fits for 5th generation VIKING 3350 and 2450 platforms.
