OUR APPROACH

Start with the
right questions.

What engine is it for? How will it be used? What needs to change? These questions shape a meaningful discussion about a custom piston.

We focus on the details of the part and the requirements of the project. Product suitability, specifications and delivery arrangements are reviewed individually.

Our custom approach

THE JND APPROACH

Connect the requirement with the finished part.

01

Start with what you have

An OEM cast sample can provide a starting reference for a forged-piston design. Sample analysis and 3D development are different stages from the finished product.

PRECISION & VALIDATION

Consistency, part after part.

Consistency, part after part.
01

Weight matching within ±1 g

Piston weight matching is controlled within ±1 g for specified matched sets. Precision tolerances and dimensional consistency are part of the agreed inspection requirements.

02

OEM experience. Racing development.

JND brings OEM experience and OEM-level validation practices into performance piston development, supported by extensive R&D and motorsport resources.

APPLICATIONS & CUSTOM DEVELOPMENT

Built around the way you use it.

Built around the way you use it.
01

Performance engine coverage

Replacement and upgrade solutions cover selected Japanese, European and American performance engine platforms, with application-specific matching for competitive and high-performance street builds.

02

Specialist diesel-racing projects

Specialist aluminium and steel piston designs address the high-temperature, high-pressure loads of diesel-racing applications. The design and material are selected for each project.

03

From a sample, drawing or idea

Custom piston development supports specific dimensions, compression ratios and engine combinations, with a flexible approach to project requirements and cost planning.
