The Trussmember is a proprietary engineered engine cradle by Coty Built that houses engine accessories, belt drive, and suspends the TDi engine assembly. With accessories mounted in OE-like locations, connecting hydraulic lines and routing electrical components is intuitive, ensuring no clearance issues with your 4-link suspension.

• Compatible with both YJ and TJ applications.
• Only the weld-in pedestals vary to ensure proper fitment and driveline alignment.
• Designed around the AC, alternator, and PS pump from a '97 2.5L 4-cylinder TJ. Other years may require modification for clearance and are not recommended.

Currently, The Cotybuilt conversions systems support only manual gearboxes. We have designed a cast aluminum adapter plate with CNC crank adapters that reposition the oem Jeep* Flywheel allowing builders to retain Jeep specific clutch kits.

When building the YJ and TJ, the gearbox’s original location remains unchanged allowing full compatibility with existing lift kits and Jeep performance parts. 

Gear boxes supported AX5*, AX15, NV3550, NSG370

Due to the low target speeds for most Jeeps, oe Volkswagen air to air inter cooling was not the optimal choice. Cotybuilt has packaged a liquid cooled after cooler and preformed all the boost plumbing in black silicon pipes to facilitate a neat and tidy under hood installation. The shorten boost track combined with the stable intake temp range allow the engine management software to be optimized for immediate throttle response on and off the trails.
