GH Professional Standards

Quality is decided by physics.

We don't base quality on blind trust in logos stamped on components. We reject market pressure to lower costs. Our guarantor is a rigorous laboratory, uncompromising selective matching and integration engineering.

Verification Procedures.

Phase 01

Selective Matching

We build our systems on proven components, both our own and from renowned partners. However, there's no room for a lottery here. We guarantee full repeatability of the control process. Every raw material batch, regardless of origin, is subject to verification in our machine park before being allowed into the assembly phase.

Rejection Criteria

  • Dimensional deviations above micrometric tolerance.
  • Inhomogeneity of metal alloy structure.
  • Non-compliance with the master characteristic curve.

Phase 02

Analysis and Harmonization of Struts

A complete MacPherson strut is a complex dynamic system. The mere presence of a new spring means nothing if its characteristics do not harmonize with the shock absorber. Our process solves this problem.

Test Scope

  • Spring Rate Testing: We test the behavior of springs under a given vertical load.
  • Damping tuning: Selection of shock absorber valving for spring dynamics.
  • Thrust bearing test: Verification of the smoothness of the upper mount rotation under full pressure simulating the vehicle weight.

Phase 03

Laboratory Steering Knuckle Assembly

Improper bearing seating using a manual press in a workshop is the most common cause of complaints in the industry. We move this risky process to our controlled production environment, eliminating human error.

Seating Standards

  • Casting geometry control: Micrometric checking of the bearing seat tolerance before pressing.
  • Force monitoring (kN): Hydraulic seating with strictly calibrated pressure, preventing race micro-cracks.
  • Lateral runout verification: Rotational test of the assembled hub ensuring perfect alignment and no vibrations during driving.

Quality we give hard evidence for.

Our control and selection process are not just slogans. That's why GH Premium is covered by an unconditional 2-year warranty with no mileage limit.
