Datsun Roadster & Fairlady Upper A-Arm Spindle Link
Upper control arm Spindle link forging. This part was not made by Rare parts but was made by the same company that made all our other suspension parts that passed with flying colors!
We openly share with our customers test results and conversations we had during development of this part
When asked if this part could be made with higher Rockwell hardness Danny Burgess at Rare Parts, who performed the testing of this part, advised that Rockwell hardness numbers above design standards for parts such as this can be too brittle and lead to premature failure. His recommendations are from years of engineering experience making parts for his own product line similar to these spindles. We deeply respect his 29 years of experience with a strong background in Science, Technology, Engineering, and Math and followed his assessment of the comparative analysis of the original Nissan parts and the subsequent new production examples that passed in testing. A engineer who has the proper testing tools, equipment and testing facility with impeccable qualifications. You can't beat that for integrity!
A careful and thorough job with over a year of development and testing was performed in making these parts available.
