Albero motore 4421 HOT RODS

Building on the success of high-quality, OEM replacement rods, Hot Rods introduced the perfect place to showcase them — in a complete heavy duty Hot Rods OEM replacement crankshaft. Since that time, Hot Rods heavy duty crankshafts have been regarded as the premier alternative to costly OE manufactured cranks. But, in addition to being a cost effective alternative, Hot Rods heavy duty crankshafts also bring a level of uncompromising quality, design and innovation not seen in its competitors.

Additional Hot Rods crankshaft features:

• All crankshafts are sold complete and ready for installation with the original proven Hot Rods connecting rods, top end bearings, and crankshaft webs
• Factory assembled and trued to OEM specifications, Hot Rods cranks will meet or surpass the OEM in performance and durability
• Crankshafts are fully re-buildable with genuine Hot Rods connecting rods and bearings
• Multi-cylinder applications are sold complete with main bearings (unless specified otherwise).
• Two and four-stroke applications available

In addition to Hot Rods heavy duty OEM replacement crankshafts, Hot Rods also offers a full line of drop-in stroker crankshafts. Not only do these stroker cranks bring about a heightened level of performance and increased displacement, but do so without costly case machining, custom cam chains or spacer plates. Better yet, many Hot Rods stroker cranks even utilize the engine's stock piston.

One single connecting rod is where it all began for Hot Rods and now, with almost two decades of experience, continuously improved designs and an ever expanding line of applications; Hot Rods has continued to be, not only “The Original” aftermarket replacement rod, but the best aftermarket replacement rod.

All of our rods are created from 8620 case hardened steel. But, in addition to that, our rods also undergo a special forging process which helps to improve grain flow as well as dimensional consistency — and that means a rod of uncompromising strength.

To improve fatigue durability, all Hot Rods rods are shot peened. This process, utilizing a stainless steel shot, helps to remove stress risers and creates smoothly blended radiuses. In the end, a Hot Rods connecting rod is one of the most durable rods that enthusiasts and engine builders can buy.

However, a rod is only as good as its supporting parts and that’s why a Hot Rods kit features only the most advanced and durable bearings. Case hardened and silver coated, the bearings are just as tough and reliable as the rods.

Even Hot Rods crank pins are subjected to the same rigorous standards as the rods and bearings. Each crank pin is created from hot-rolled ASTM 4115 steel and case-hardened to a level of 58–62 Rc.

Additional Hot Rods connecting rod features:

• Double-honed bearing surfaces to provide a reliable, high RPM rod
• Double-drilled small ends for increased wrist pin lubrication
• Bronze bushings in the small end of all four-stroke rods to maximize durability under high-loads and prevent galling
• Specially designed vent slots in the large end of all two-stroke rods for improved lubrication
• Side scalloping on large end to minimize high RPM rod distortion

To compliment Hot Rods full line of heavy duty OEM replacement and stroker crankshafts are Hot Rods complete main bearing and seal kits for both two and four-stroke applications. Like other Hot Rods products, these main bearing and seal kits are built to the highest quality standards that meet or exceed those of OEM.

Additionally, not only will Hot Rods main bearing and seal kits work in rebuilding a Hot Rods crankshaft; but, they also work in rebuilding OEM cranks as well.
