Varying piston weight will alter balance factor only – call for details
Heat-treated 4140 flywheel material with integral shafts are harder and 114% stronger than stock. Reduced mainshaft deflection is achieved and verified sprocketshaft & pinionshaft total indicated run-out tolerances of < .0015” at the main bearing races is the tightest in the industry.
The 1.671" diameter crankpin with increased contact area and tighter press fit and the DH proprietary Pro-Plug system & a welded crankpin are coupled together for a stronger joint to STOP scissoring on the crankpin. Integral mainshafts combined with the DH Competition connecting rod kit produces this Rock Solid Foundation for the most powerful of motor builds.
Certified assemblies have met the strictest of tolerances, balanced for 1,035 gram TC Full-top conn-rod compatible pistons & blueprinted by DH craftsmen. Utilizing proprietary methods of consistent balancing and precision machining equates to truer flywheels with less vibration as an assembly. All crankshafts are gear driven camshaft compatible and tolerances are documented so you do not have to (but we still recommend verifying).
