How to find the right Automotive Performance Push Rod Tubes AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Automotive Performance Push Rod Tubes

Engine family fit
Buy tubes made for your exact engine family, such as air-cooled VW, a specific Harley-Davidson platform or another air-cooled design. Tube length, end shape and seal type differ between engines and are not interchangeable.
Fixed vs adjustable/collapsible
Choose collapsible or quick-install tubes if you will change cams with the heads on. Collapsible tubes let the pushrods come out without pulling the heads.
Seal material
Use heat- and oil-resistant seals specified for the tube, and replace them whenever the tubes come out. Pushrod tube seals are a common oil leak point on air-cooled engines.
Length setting on VW-type tubes
Set stock-style VW tubes to the length in the engine manual when you reuse or replace them. Tubes that are too short do not compress the seals and will leak.

Brands that matter

  • Empi: Common source of air-cooled VW pushrod tubes and seals.
  • S&S Cycle: Harley-Davidson pushrod tubes and valvetrain parts.
  • Feuling: Harley-Davidson valvetrain and quick-install pushrod tube components.

What to avoid

  • Reusing old, hardened pushrod tube seals.
  • Tubes that do not name a specific engine fitment.
