Description

If you're building a Twin Cam 88 engine that demands precision and longevity, KB Performance pistons are engineered to deliver tighter tolerances and superior ring seal that production alternatives simply cannot match. The T-5 heat-treated 390 hypereutectic aluminum construction allows for a significantly tighter piston-to-wall fit, which reduces piston rock, minimizes blowby, and extends both piston and ring life. When every tenth counts, these diamond-machined pistons held to plus-or-minus one gram weight tolerance ensure consistent performance across your entire build.

Technical Specifications:

  • 390 hypereutectic aluminum alloy
  • T-5 heat-treated construction
  • Diamond-machined finish
  • ±1 gram weight tolerance
  • ±0.0005" piston-to-piston tolerance
  • Allows tighter wall clearance
  • Reduces piston rock significantly
  • Improves ring seal performance
  • Includes two pistons per kit
  • Wrist pins included
  • Spiral-lock pin clips included
  • Hastings moly rings included
  • Designed for Twin Cam 88
  • Bolt-on installation
  • MPN: KB425C.005

Note: Review included instructions for proper piston clearance and top ring end gap specifications before installation. Replacement rings sold separately if needed.
