Viair 400C Air Compressor Rebuild Kit – Connecting Rod & Piston (RK157)

If your Viair 400C air compressor is getting tired or just needs a refresh, grab this RK157 rebuild kit.

It includes the connecting rod and piston—the guts of the pump.

Brand new, direct from Viair (or Viair-compatible), with that classic silver metallic finish.

Made in China, but it's the exact part you need to get your onboard air system back in action.

Quick note: Prop 65 warning applies (lead exposure warning), but that's on basically every metal part sold in California.

No warranty on this one, but it's a brand new part ready to install.

Get your compressor pumping again.
