S-PARTS Öhlins MTB Fork Titanium Air Spring Top Cap & RXF38 Front Thru Axle

S-PARTS Titanium Upgrade Parts for Öhlins MTB Forks

Upgrade your Öhlins mountain bike suspension fork with precision-engineered S-PARTS TC4 titanium hardware.

Designed for riders who value lightweight performance, strength and premium finishing, this collection includes titanium front thru axle and fork top cap options for compatible Öhlins MTB suspension forks.

Each component is manufactured from carefully selected TC4 (Ti-6Al-4V) titanium alloy and precision machined for accurate fitment, clean threads and dependable installation.

Premium TC4 Titanium Alloy

S-PARTS uses selected S-grade TC4 (Ti-6Al-4V) titanium alloy with an average tensile strength exceeding 1050 MPa.

TC4 titanium offers an outstanding strength-to-weight ratio, excellent corrosion resistance and approximately half the density of steel, making it an ideal material for premium mountain bike hardware.

• Premium TC4 (Ti-6Al-4V) titanium alloy
• Average tensile strength above 1050 MPa
• High strength-to-weight ratio
• Excellent corrosion resistance
• Designed for lightweight MTB builds

Precision Manufacturing

S-PARTS titanium hardware is manufactured using dedicated tooling, precision forging and CNC machining processes.

Forged components are processed using dedicated hot-forging dies at approximately 650°C. Each forging die is limited to approximately 300 production cycles to help maintain manufacturing consistency.

Precision multi-axis CNC machining is then used to control critical dimensions and threaded interfaces, providing accurate thread engagement and consistent fitment.

Titanium Front Thru Axle

The S-PARTS titanium front thru axle is designed as a premium replacement for the compatible original Öhlins fork axle.

It combines the strength and corrosion resistance of TC4 titanium with a refined appearance, making it ideal for riders looking to upgrade small but highly visible components on a premium MTB build.

Please select the version that matches your exact Öhlins fork model and original axle specification.

Titanium Fork Top Cap

The matching titanium fork top cap provides another detail-focused upgrade for compatible Öhlins suspension forks.

Precision machining and multiple titanium finishes allow the top cap to coordinate with other S-PARTS titanium hardware across your bike.

PVD & Anodized Titanium Finishes

S-PARTS offers multiple finishing processes to create distinctive titanium colors without relying on conventional paint.

Selected finishes use vacuum PVD treatment, while other colors are produced through anodizing. Anodizing creates a controlled oxide layer on the titanium surface, allowing different colors to appear through variations in oxide thickness and light interference.

This provides a premium metallic appearance while preserving the distinctive character of titanium.

Built for Premium MTB Builds

A high-end suspension fork deserves hardware with the same attention to detail.

Whether you are building a lightweight trail bike, an aggressive enduro machine or simply refining the details of your Öhlins-equipped MTB, S-PARTS titanium components provide a combination of low weight, strength, corrosion resistance and premium aesthetics.
