Diamond Series:
better than oem

The Rare Parts Diamond Series is a collection of all of the steering and suspension parts we design, engineer, test and manufacture – all designed to exceed the OEM specifications.

Tie Rod End Tester

This machine is used to life cycle tie rod ends – during the design and development phase. We can apply different loads in both compression and tension, as well as articulate the ball stud at multiple angles. This simulates the actual loads and articulation seen during normal and extreme driving conditions. Parts are cycled for hundreds of thousand of cycles, and periodically checked for wear of ball studs and as well as for condition of mating components.

Pinti Ball Joint Tester

Similar to the job of our tie rod end cycle tester, this machine life cycles ball joints. This machine will simulate side loads, vertical loads, compression loads and rotational loads all seen on a vehicle. When new material and components are used in designs we use this machine to verify function and durability of the design. A good example of a new design never tried before is the upper ball joint from our Dual Load Carrying Ball Joints for Jeep JK. Different bearings and material were cycled in this machine, until wear and durability results were to our satisfaction.
See Video.

Tensil-Tester

This machine is used to verify material strengths, in both pull-out and push-out, for different steering and suspension parts. One example would be the ball stud pull-out strength of our Chevy HD tie rod assembly, verses the strength of the OE part. Another example would be the pull-out strength of our forged T-bird ball joint, verses that of the OE stamped design.
