EC Billet Side Cover – 7-Bolt Design for Wildcat 223 Hemi Engines


Built specifically for the Wildcat 223 Hemi engine platform, the EC 7-Bolt Billet Side Cover is engineered for strength, precision, and performance. This high-quality upgrade replaces the factory side cover with a CNC-machined billet aluminum housing that enhances durability, oil control, and crankcase sealing—perfect for racing go-karts, mini bikes, and high-output utility builds.


Unlike generic billet covers that sacrifice oil capacity or overlook the unique 7-bolt Wildcat block layout, this side cover is precision-matched to the Wildcat 223's bolt pattern and performance needs.


Key Features:

Precision Fit for 7-Bolt Wildcat 223 Hemi

  • Specifically designed for the unique 7-bolt pattern used in the Wildcat 223 block.
  • Offers a direct bolt-on replacement—no drilling or modifications required.

Maintains Full Engine Oil Capacity

  • Internal cavity mirrors the OEM shape to retain factory oil volume.
  • More oil means better heat control, reduced wear, and longer oil life.

Crankcase Ventilation & Pulse Port

  • No built-in PCV to simplify setup—ideal for racers using catch cans or vented systems.
  • Includes pulse fitting for fuel pump or optional oil routing applications.

Top Oil Fill & Billet Dipstick

  • Oil fill relocated to the top of the side cover for starter and tank clearance.
  • Includes a front-mounted billet dipstick for quick access—especially useful on mini bikes and karts.
  • Black anodized finish on oil cap and dipstick prevents galling and seizing.

Superior Sealing & Strength

  • Machined O-ring groove offers leak-free sealing around the crankcase perimeter.
  • Reinforced with two solid dowel pins for precise alignment and block stability.
  • Secured using standard 8Mx35 cap screws (Stud Kit available separately for added clamping force).

Integrated Camshaft Bearing Support

  • Cam bore includes a replaceable steel bearing for reduced friction and extended wear resistance.
  • Outperforms bronze bushings or aluminum-on-aluminum setups.

  • CNC-Machined Billet Side Cover (7-Bolt Pattern)
