Review VOLKSWAGEN Vw Bug Type Transaxle fits IRS 1968–1972

Introducing the Volkwagen Type 1 Transaxle IRS (Independent Rear Suspension) unit, part number 38-113.301.103-E, specifically designed for Volkswagen Beetles manufactured between 1968 and 1972. This transaxle assembly is a crucial component of the vehicle's powertrain system, responsible for transferring power from the engine to the wheels while also providing independent rear suspension for improved handling and ride quality.

The Type 1 Transaxle IRS is a sophisticated piece of engineering, featuring a compact design that integrates the engine, transmission, and differential into a single unit. It is a front-engine, rear-wheel-drive system with a transverse engine layout. The engine drives the front wheels through a conventional transmission, while the rear wheels are driven through the transaxle assembly.

The transaxle housing is made of strong, durable cast iron, ensuring excellent heat dissipation and longevity. The unit houses a 4-speed manual transmission with a synchronized 1st, 2nd, and 3rd gear and a direct 4th gear. The transmission is mated to a heavy-duty, oil-cooled differential with a 41-element gear train, providing efficient power transfer and smooth operation.

The transaxle assembly also includes an integrated clutch system, featuring a diaphragm clutch and a multi-plate clutch. The clutch system facilitates the engagement and disengagement of power between the engine and the transmission, allowing for seamless shifting.

This transaxle IRS unit is also equipped with a rear suspension system featuring trailing arms and torsion bars. The independent suspension design allows each wheel to move independently, reducing tire wear and improving overall vehicle stability and handling.

The unit comes fully rebuilt and tested to ensure optimal performance and reliability. Each rebuilt transaxle undergoes a thorough inspection, cleaning, and replacement of all worn or damaged components. The housing is media-blasted and repainted, while new seals and gaskets are installed to ensure a leak-free operation.

Furthermore, this VW Type 1 Transaxle IRS comes with a new clutch kit, including a clutch disc, pressure plate, release bearing, and pilot bearing. This ensures a perfect clutch engagement and eliminates the need for an additional clutch kit purchase.

Overall, the Volkwagen Type 1 Transaxle IRS (part number 38-113.301.103-E) is a high-quality, fully rebuilt and tested component designed to restore the power, handling, and reliability of your 1968-1972 Volkswagen Beetle. With its compact design, efficient power transfer, and advanced independent rear suspension system, this transaxle assembly is an excellent investment for any Volkswagen enthusiast.
