WEHRLI CUSTOM FAB WCF100118 UNIVERSAL T4 SPACER PLATE KIT 0.5IN W/STUDS & GASKETS

Wehrli WCF100118 Universal 1/2" T4 Spacer Plate Kit w/ Studs & Gaskets

The WEHRLI WCF100118 UNIVERSAL T4 SPACER PLATE KIT is a 1/2" thick, divided T4 spacer plate designed for builders who need extra room and flexibility when mounting a T4 flange turbocharger. Built from heavy steel and ceramic coated black, this spacer helps with turbo clocking, compressor housing clearance, manifold and valve cover clearance, and custom fabrication layouts on a wide range of turbo setups.

Whether you are dialing in a custom single, compound, or remote-mounted T4 turbo, this WCFab spacer plate makes it easier to position the charger where you want it while maintaining a durable, leak-free seal between the turbo and T4 mounting surface.

Key Features & Benefits

• 1/2" thick steel divided T4 spacer plate for extra turbo mounting height and clearance.
• Universal T4 flange pattern for use with most T4 frame turbochargers and pedestals.
• Ceramic coated black to help manage heat and resist corrosion in high-temperature environments.
• Includes M10 mounting studs (~1" long), nuts, and washers for a secure, serviceable install.
• Comes with (2) T4 gaskets to properly seal both sides of the spacer plate.
• Ideal for custom turbo kits, manifold conversions, and tight engine bay layouts.
• Quality Wehrli Custom Fab (WCFab) hardware backed by CPP Diesel support.

What's Included

• 1/2" thick steel divided T4 spacer plate, ceramic coated black.
• M10 mounting studs (approx. 1" long).
• M10 nuts and washers.
• (2) T4 turbo mounting gaskets.

Vehicle Fitment & Typical Applications

This kit is listed as a universal part and is intended for use with T4 flange turbochargers and T4 pedestals, including a wide range of Dodge/RAM Cummins diesel applications and custom builds.

Typical diesel applications include (not limited to):

• 1994-2002 Dodge / RAM 5.9L Cummins turbo conversions using a T4 flange manifold or pedestal.
• 2003-2007 Dodge / RAM 5.9L Cummins with T4 swap manifolds or custom turbo kits.
• 2007.5-2018 Dodge / RAM 6.7L Cummins custom T4 turbo setups.
• 2019-2022 Dodge / RAM Cummins and other T4 turbo conversion projects.
• Universal T4 flange turbo projects on other diesel or gasoline performance builds.

If your turbocharger or turbo pedestal uses a standard T4 flange pattern and has adequate stud/bolt length or can accept the supplied M10 studs, this spacer plate kit can usually be integrated into your setup. Always verify clearances and flange compatibility before installation.

Installation & Usage Notes

• The spacer installs between the T4 turbo mounting flange and the T4 manifold or pedestal, raising the turbo approximately 0.5" to help with clearance and turbo clocking.
• Use the supplied M10 studs, nuts, and washers to secure the turbo and spacer. Torque fasteners evenly in a criss-cross pattern to ensure a flat, even seal.
• The two included T4 gaskets are intended for both sides of the spacer (manifold-to-spacer and spacer-to-turbo). Always inspect both flange surfaces for flatness and cleanliness before assembly.
• Re-check fastener torque after initial heat cycles, especially on fresh builds or high-heat applications such as towing, racing, or sled pulling.
• This spacer is for off-road / competition use in some regions. Always follow local emissions and safety regulations.

Specifications

FAQ

This 1/2" T4 spacer plate raises the turbocharger off the manifold or pedestal, providing extra clearance for compressor housings, manifolds, and other components. It can also help fine-tune turbo position and clocking in tight engine bays or custom turbo kits.

It is considered "universal" for T4 flange turbos and pedestals. As long as your setup uses a standard T4 mounting pattern and you can use M10 studs or adapt to them, this spacer can typically be integrated. Always verify bolt pattern, flange size, and clearances for your specific application.

In some custom race applications, builders will stack spacers to achieve specific turbo locations. If you plan to stack this 1/2" spacer with the 1" or 1.5" Wehrli T4 spacer kits, ensure your stud length, flange engagement, and overall support are adequate, and re-check for leaks and stress on manifolds and pedestals.

The spacer primarily changes turbo mounting height and geometry. Any effect on spool characteristics is generally minor compared to turbo sizing, piping layout, and tuning. It is mainly a clearance and packaging tool that makes your turbo placement more flexible.

Because it is used in custom turbocharger installations and may alter emissions-related systems, it is not CARB legal for sale or use on pollution-controlled vehicles in California and some other regions. Always check local regulations before using on a street-driven vehicle.
