Gearbox Rebuilds

Motorsport Gearbox Rebuilds Near Silverstone

At Ben Sharpe Racing, all gearbox rebuilds are carried out in-house within a clean, controlled workshop environment near Silverstone Circuit.

This isn’t a quick turnaround job or a basic refresh.
It’s a methodical, lab-style process where every component is stripped, cleaned, inspected and measured against exact tolerances before reassembly. Nothing is rushed. Nothing is assumed.

The result is a gearbox built to handle the demands of serious track and race use.

​

Our Gearbox Rebuild Process

Every rebuild follows a structured, engineering-led approach:

​

Full Strip & Inspection

Complete disassembly of the gearbox to assess internal condition and identify wear patterns.

​

Component Cleaning & Preparation

All parts are thoroughly cleaned and prepared for accurate inspection and measurement.

​

Tolerance Checking

Critical components are measured against manufacturer and motorsport tolerances.

​

Wear & Weak Point Identification

We don’t just rebuild — we improve. Known weak areas are addressed to increase reliability.

​

Precision Reassembly

Gearboxes are rebuilt with care, accuracy and attention to detail throughout.

​

Built for Track & Race Use

Our gearbox rebuilds are designed for:

• Track day cars under sustained load

• Race cars requiring reliability under pressure

• High-performance road cars used on circuit

• Drivers experiencing gearbox issues or degradation

• Preventative maintenance for serious builds

Whether it’s a refresh or a full motorsport-spec rebuild, the goal is the same, confidence under load.
