Product Details

The JE Pistons 361729 Ultra Series Piston Set delivers race-proven performance in a ready-to-run package. Forged from high-strength 2618 aluminum alloy, these pistons are engineered for high-boost, high-horsepower applications where durability under extreme thermal and mechanical stress is non-negotiable. This set includes 8 pistons featuring an inverted dome/dish crown design, a 4.005-inch bore, 1.115-inch compression distance (CD), and a 0.927-inch wrist pin diameter.

Key Features:

  • 2618 Forged Aluminum Construction — A premium aerospace-grade alloy chosen for superior toughness and fatigue resistance under high-boost and forced-induction conditions
  • Inverted Dome/Dish Crown — Optimized crown geometry for controlled combustion efficiency and target compression ratios
  • Thermal Barrier Crown Coating — Reduces heat transfer into the piston crown, protecting the aluminum under extreme combustion temperatures
  • Lateral Gas Ports — Improve ring seal by equalizing pressure around the top ring land, enhancing power and reducing blowby
  • Thick-Wall Wrist Pins — Heavy-duty 0.927-inch diameter pins resist deflection and fatigue at high RPM and cylinder pressures
  • Revolutionary Forging Technology — Advanced forging process produces a stronger grain structure for increased strength-to-weight ratio
  • 4.005-Inch Bore Diameter — Precision-machined for consistent sizing across all 8 pistons in the set
  • 1.115-Inch Compression Distance — Engineered for proper deck clearance and correct piston positioning at TDC

The JE Pistons Ultra Series is built for serious performance builds — including turbocharged, supercharged, and nitrous-assisted engines — where off-the-shelf pistons simply won't hold up. Each piston in this set is manufactured to exacting tolerances, making them a trusted choice among professional engine builders and motorsport competitors worldwide.
