Engineering

Precision. No Compromises.

Every D1RT damper starts as a SolidWorks model. It finishes as a CNC-machined, bench-tested instrument. Nothing ships until it passes.

Design Process

SolidWorks to the Dirt

Every D1RT damper begins life as a parametric SolidWorks model. FEA (Finite Element Analysis) simulates real-world load cases — tank-slappers, rock strikes, high-speed compressions — before a single piece of metal is cut.

We iterate in the digital world until the design is proven. Only then does the CNC machine start cutting. This approach eliminates costly physical prototyping cycles and means the first physical damper is already very close to production specification.

Manufacture

CNC Billet. Every Part.

Die-cast or forged components have no place in a D1RT damper. Every body, every valve housing, every mounting bracket is CNC-machined from solid billet aluminium stock — 7075-T6 for high-stress components, 6061-T6 where weight reduction matters.

Machining tolerances are held to ±0.01mm on critical bore diameters and valve seats. Surface finishes are specified and verified — not assumed. The result is a damper that assembles with zero slop, operates consistently across temperature ranges, and doesn't wear out of spec.

All machining is performed by our manufacturing partner using 5-axis CNC centres with in-process measurement. Every critical dimension is documented. Nothing leaves without a conformance record.

Warranty

Unlimited Mechanical Coverage

If a D1RT damper fails mechanically — any component, any cause — we fix it or replace it. No time limit. No kilometre cap. No questions. Seal kits have a 2-year coverage period. Return-to-base applies. That's it. That's the whole warranty.
