Hot Rods Heavy-Duty Connecting Rod Kit for 4-Cycle 250cc Engines

Elevate your engine's performance and reliability with the Hot Rods connecting rod kit, a premium heavy-duty OE replacement designed for 250cc 4-cycle engines. This meticulously engineered kit provides superior strength and exceptional longevity, making it the ideal choice for engine rebuilds and performance upgrades.

Description

This Hot Rods heavy-duty connecting rod kit is engineered to withstand the rigors of high-performance motorcycle engines, ensuring unparalleled durability and consistent power delivery. Each component is crafted from top-tier materials; the rod itself is made from certified 8620 AISI steel, renowned for its superior strength and resilience. The crankpins are manufactured from hot-rolled ASTM 4115 steel, then case hardened to a robust level of 58-62Rc, providing exceptional wear resistance. Designed for high RPM longevity, the kit features the latest caged needle roller bearing designs. The uniquely designed big end incorporates strategically located side scalloping and vent slots, effectively minimizing bearing race distortion even under extreme rotational speeds. Furthermore, the small ends are double drilled to deliver extra lubrication and cooling directly to the wrist pin bearing, a critical feature for maintaining bearing integrity when the piston crown operates close to the bearing. To enhance fatigue resistance and smoothly blend the rod forging's radiuses, each rod is shot-peened. Precision double honing produces an ultra-round bearing surface, crucial for reliability and smooth operation at high RPMs. This comprehensive kit includes the rod, crank pin, crank pin bearing, top-end bearing, and silver-coated bronze phosphor thrust washers, ensuring a complete and seamless installation. Compatible with both Hot Rods and original equipment (OE) crankshafts, this 4-cycle engine connecting rod offers a reliable solution for your motorcycle engine rebuild.
