ARC Billet Duplex Crankcase Cover for Briggs OHV Stroker Engines

Billet excellence redefines crankcase protection—this ARC duplex cover elevates stroker builds in Briggs OHV blocks to elite status.

Machined from solid aluminum, it houses duplex timing gears with unmatched precision, vital for extended strokes that demand flawless synchronization.

• Fits only 555705 blocks with stroker cranks; skips OEM casts for mod purity.
• Streamlined internals cut parasitic drag, freeing horsepower at high revs.
• Integrated baffles optimize oil splash, preventing starvation in corners.

Note: Images approximate; real unit shines in detail (SKU: ARC6053). Modifiers install it to harness longer throws, yielding torque monsters that dominate straights.

The duplex setup ensures chain tension stays perfect, minimizing slap and wear—key for engines spinning past stock limits. In open karting, where power rules, this cover fortifies the bottom end against catastrophic failure.

Consider the gains: reduced oil aeration means cooler, consistent lubrication, letting you hold gears longer in battles. Builders rave about its CNC tolerances, aligning components like never before for vibration-free runs.

Beyond strength, the billet's thermal conductivity dissipates heat faster, protecting bearings during brutal sessions. For stroker enthusiasts, it's not optional—it's the foundation for chasing 10,000 RPM dreams safely.

Trackside, teams with ARC covers report fewer teardowns, as the robust seal keeps contaminants out and pressure in. Pair with high-volume pumps for oiling that matches the ambition, turning a block into a beast.

In the world of modified karts, where every gram and degree counts, this cover stands as a testament to engineering prowess. It empowers tuners to push boundaries, delivering laps that echo through the paddock long after the checkered flag.
