Description

Connecting Rod Kit - Yamaha Upgrade your Yamaha engine with the HOT RODS 8121 connecting rod kit, engineered for durability and high-performance reliability. Crafted from certified 8620 AISI steel, these heavy-duty connecting rods provide superior strength and longevity for demanding applications. The use of high-grade materials ensures that the rods can withstand extreme stresses while maintaining structural integrity during high RPM operation. Each rod features crankpins manufactured from hot-rolled ASTM 4115 steel, case hardened to a level of 58-62 Rockwell C, which enhances wear resistance and overall durability. These design elements make the rods an excellent choice for both stock replacements and high-performance builds.
The rods incorporate the latest in caged needle roller bearing technology, optimized for high RPM longevity and reduced friction. The large end of each rod is uniquely designed with strategically located side scalloping and vent slots, aimed at minimizing bearing race distortion during high-speed operation, thus ensuring smoother performance and extended bearing life. The small ends are double drilled to supply extra lubrication and cooling to the wrist pin bearing, an essential feature when the piston crown is situated close to the wrist pin. Shot-peened to eliminate surface stress risers, the rods also feature radiused forging surfaces that are smoothly blended for enhanced strength and reliability.
Manufactured in the USA, these rods are assembled with precision, including double honing to produce an ultra-round bearing surface for high-speed reliability. Most rod assemblies are sold complete with the rod, crank pin, crank pin bearing, top-end bearing, and silver-coated bronze phosphor thrust washers, simplifying installation and ensuring compatibility. Designed to work seamlessly with Hot Rods and OE crankshafts, the HOT RODS 8121 connecting rod kit is a reliable choice for enthusiasts seeking high-performance, durable replacement parts for Yamaha engines.
