Racing Connecting Rods

Better Material,Better Design,More Precision,More lightweight...

All YOUFU rods forging is made of air space high-quality 40CrNiMoA Alloy Steel(American SAE 4340) for all high performance racing rods. The rod itself and cap have been stamped and forged separately which ensures the fiber direction of metal structures conformable to the stress direction during the movement of the connecting rod and further maintain the strength of the rod. Auto Controlled Continuous Furnace is employed for heat treatment and this kind of treatment ensures the strength inside and outside the torging stay the same and also improves the mechanical property significantly.

 

A. Big End Tolerance: +/-0.00017"                                                  

B. Small End Tolerance: +/-0.00017"                                                

C. Verticality, Parallelism and Distortion: +/-0.00018"                            

D. Center to Center Distance Tolerance: +/-0.001"                                  

E. Verticality and Parallelism Tolerance between Two Bolt Holes: 0.0004"         

F. Return Tolerance of Big Hole Repeat Assemble: 0.00018"

 

3. Coverage factor of cloudbursting is 100%. After cloudbursting, the connecting rods will be stress arising from the machine work and to from deformation.

 

4. Inspect each procedure completely in order to prevent defective works from entering into the following procedure and to further ensure 100% pass.

 

5. Manufacture the connecting rod in consideration of the properties of ARP bolts used in order to produce a perfect operation between the bolt and the rod.

 

6. Balance Weight of Big and Small Ends: weight difference of every small end is not more than +/-1g and its total weight is not more than +/-1g.
