-
Billet 4340 Steel Crankshaft: Aerospace‑grade billet crank for maximum durability in high‑boost/high‑load environments.
-
Custom Forged Pistons: CP or JE forged pistons, available in your chosen bore size and compression ratio for tailored performance.
-
Heavy‑Duty Hardware: 9310 alloy wrist pins, premium ring pack (ductile iron plasma top, tapered second, low‑tension oil ring), and ARP fasteners.

Balanced & Ready: System‑balanced components ready for professional assembly.
Option 1: ProH625+ Rod Kit — Balanced Strength
- Brian Crower BC0328LW Stroker Kit
Specifically equipped with BC’s ProH625+ connecting rods, this configuration blends strength and reliability across a wide power band. The H‑beam style rods and proven fastener package make this the go‑to choice for high‑horsepower street, track, or drag applications where all‑around durability is desired.
Best For: Balanced performance builds — turbo, twin‑turbo, or high‑boost applications where consistency and strength are priorities.
Option 2: MOAR I‑Beam Rod Kit — Elevated Performance
- Brian Crower BC0329LW Stroker Kit
This variant swaps the ProH625+ rods for MOAR I‑beam connecting rods with ARP625+ fasteners, offering improved dynamic response and strength at sustained high RPMs. The I‑beam design excels in competition scenarios or high‑revving setups.
Best For: Aggressive builds targeting higher RPM limits, sustained load competition engines, or where every bit of internal strength counts.
Compatibility
- 2020+ GR Supra w/B58 3.0L
