Prime Race Parts | Titanium Pro Mod Tunnel Kit 650mm

Prime Race Parts Titanium Pro Mod Tunnel Kit

Part number: 16501

Build a lightweight, professional driveline enclosure with the Prime Race Parts Titanium Pro Mod Tunnel Kit, designed for serious drag racing and Pro Mod-style chassis applications where strength, weight reduction and clean fabrication are critical.

Manufactured from titanium, the tunnel provides an excellent combination of strength and low weight while giving fabricators a purpose-built foundation for enclosing the driveline area in high-performance race vehicles.

The tunnel measures 650mm long, 254mm wide and 133mm high, providing generous driveline clearance while maintaining a compact profile suited to tightly packaged race-car interiors. This tunnel fits a 1480-size Uni joint and yoke!

Each kit is supplied with two complete tunnel loops, pre-notched and ready for the fabricator to establish the final installed height before welding. This significantly reduces fabrication time while allowing the tunnel position to be tailored to the individual chassis, driveline and floor configuration.

The kit also includes billet Titanium clevises ready for installation, providing a high-quality mounting solution and helping create a clean, professional finished assembly.

Installation & Fabrication

The supplied tunnel loops are notched and ready to install, allowing the fabricator to establish the required height and positioning within the individual chassis before final welding.

This provides flexibility for variations in driveshaft position, transmission height, differential alignment, floor structure and chassis configuration without requiring the complete tunnel assembly to be fabricated from scratch.

Professional race-car fabrication and titanium welding experience are recommended for installation.

Why Titanium?

In a dedicated race car, reducing unnecessary weight while maintaining structural integrity can provide a meaningful performance advantage.

Titanium offers an exceptional strength-to-weight ratio, making it well suited to motorsport components where durability and minimal mass are equally important. For a Pro Mod or high-level drag racing build, it also delivers the premium finish and construction expected from a purpose-built competition chassis.
