It's that little hydraulic cylinder in the manual transmission Beetle and Carmengia that lets you "press the clutch and shift gears." If it leaks oil, the clutch pedal will become sluggish and weak, or the gears will make a clicking sound when shifting gears, and in severe cases, you won't be able to shift at all. For a classic car like the Beetle, a broken clutch slave cylinder not only renders the car unusable but also significantly diminishes the owner's collector's value.

Specific Applications: 1947-2003 Volkswagen Beetle (VW KAEFER, Type 1), covering the entire production cycle from post-war resumption of production to the closure of the Mexican factory.
1949-1981 Volkswagen Beetle Convertible (VW KAEFER Convertible 15), a classic convertible model.
1957-1974 Volkswagen Carmengia Convertible (VW KARMANN GHIA Convertible 14, 34) Elegant Coupe Convertible Built by Cayman Bodyworks

Core Functions
Hydraulic Pressure Terminal Execution: Receives hydraulic pressure from the clutch master cylinder, precisely pushes the release bearing to complete the clutch disengagement action, ensuring smooth shifting.
Classic Structure for Reliability and Durability: Adopts the same classic piston and cylinder block structure as the original, highly familiar to repair technicians and classic car restoration experts, and easy to maintain.
Leak-Proof Sealing: Uses high-quality rubber seals to prevent hydraulic oil leakage, ensuring long-term stable system pressure, suitable for the conditions of restarting classic cars after long-term parking.
High Temperature and Aging Resistance: Seals are made of oil-resistant and aging-resistant materials, adaptable to the high-temperature environment of the engine compartment, and not prone to hardening and cracking even after long-term parking.
Ready to Install and Match: Mounting holes, pipe threads, and push rod lengths are all manufactured according to the original factory standards of the Volkswagen Type 1 platform, requiring no modification and perfectly adapting to classic car restoration needs.
Multi-Model Universal Interchange: One product model covers three classic models: Beetle Sedan, Beetle Convertible, and Cayman Convertible.

What problems can the XUI3552A solve for your overseas customers?
Classic car parts supply challenges: The Beetle's production cycle is as long as 56 years, and some early OE numbers have been discontinued or are in extremely unstable supply, leaving classic car restorers and clubs facing the dilemma of "having money but not being able to buy parts." The XUI3552A provides a stable and reliable alternative supply, helping customers capture the continued demand in this market segment.
High prices for original parts: Volkswagen original or ATE brand classic car parts remain expensive, and are mostly small-batch specialty orders. XUI3552A offers equivalent OE quality at a 30%-50% lower price, helping customers rebuild price competitiveness.
Three OE numbers in one, streamlined inventory: Three numbers correspond to one product model, reducing SKU count by two-thirds and significantly simplifying inventory management.
Global classic car community coverage: With over 20 million Beetles worldwide, the classic car restoration community is active in Europe, North America, South America (Brazil/Mexico), Australia, and other regions, with stable market demand and high loyalty.
Own-brand premium: Supports neutral packaging and customized brand packaging, helping customers build brand barriers in the high-value-added segment of classic car parts.

Addressing customer pain point
Original parts out of stock or limited supply: Early OE numbers such as 113 611 021 1 and 113 611 023 are discontinued or have limited supply; ATE 005109 is also frequently out of stock. XUI3552A maintains stable production, ensuring supply chain security.
Aftermarket parts vary in quality: Low-priced replacement parts on the market often suffer from poor sealing, cylinder block pinhole leaks, and pushrod length deviations, quickly failing in classic car repair scenarios. We use OE-grade materials and precision machining processes, keeping the return rate below 1%.

Difficult installation compatibility: Manufactured strictly according to the original installation dimensions and thread specifications of the Volkswagen Type 1 platform, with 100% matching of mounting bracket hole positions (Φ42/60), pushrod length, and 4-M10×1.0 piping interfaces, ensuring zero installation difficulties for technicians.

Reliability after long-term parking: Classic cars are often reused after long periods of parking, which can easily lead to aging of seals. Our seals use oil-resistant and aging-resistant materials, maintaining good sealing performance even after months of parking.

Q1: Why can XUI3552A be compatible with both the Beetle and the Comengio?
A: The Karmann Ghia is built on the Volkswagen Beetle Type 1 chassis, sharing the same powertrain, transmission, and clutch hydraulic system. Therefore, the clutch driven cylinder is completely interchangeable, with one product model covering both models.

Q2: Can all three OE numbers be replaced with XUI3552A?
A: Yes. ATE: 005109, 113 611 021 1, and 113 611 023 are all designations for the same clutch driven cylinder in different years, brands, or regional markets. There is no substantial difference in installation dimensions and hydraulic performance. XUI3552A covers all three designations through a unified design.

Q3: Is this driven cylinder an original equipment manufacturer (OEM) part or an aftermarket part?
A: It is an OE quality replacement part (Aftermarket OE Replacement). We manufacture it according to Volkswagen's original equipment manufacturer (OEM) standards and the TS16949 quality system. The installation dimensions and performance parameters are consistent with the OEM part, making it 100% replaceable.
