  • Reinforced Construction: Manufactured from high-grade cast aluminum or alloy material (depending on version) for added strength and warp resistance under heat and load.
  • Machined Bearing and Seal Seats: Precision-machined to ensure proper alignment of crankshaft bearings and oil seals—critical for maintaining oil pressure and reducing wear.
  • Ideal for Performance and Replacement Builds: Whether you're rebuilding a blown engine, upgrading for reliability, or building a performance motor, this side cover gives your crankcase the support it needs.


 Applications:

  • Wildcat 460 performance engines
  • Other 10-Bolt Block 420cc–460cc GX390-style clones
  • Used in kart racing, mini bikes, generators, and performance small engine builds


Reinforce your engine’s lower end and ensure a leak-free build with the 10-Bolt Crankcase Side Cover—trusted by engine builders for performance, precision, and peace of mind.


FAQ

A1: It fits the Wildcat 460, other big block GX390-style clone engines in the 420cc–460cc+ range with 10-bolt blocks

A2: The 10-bolt design offers improved sealing and structural integrity, reducing the chance of oil leaks or flex under high RPM or vibration—perfect for racing and high-load use.


Q3: Is this a direct replacement for my existing side cover?
A3: Yes, if your engine uses the 10-bolt pattern, this cover is a bolt-on replacement. Always confirm bolt pattern and bearing fitment before installation.
