The clutch slave cylinder (Clutch Slave Cylinder) is the other half of the clutch hydraulic system of a manual transmission vehicle that works in conjunction with the master cylinder. To put it simply: the clutch master cylinder is responsible for converting pedaling force into hydraulic pressure, and the slave cylinder is responsible for receiving this pressure, pushing the separation fork, and finally causing the clutch plate to separate to complete the shifting action. The two are in tandem, one cannot exist without the other.
If the slave cylinder has seal aging or internal wear, common symptoms include: the clutch pedal becomes soft when pressed, there is resistance to shifting or it is difficult to shift into gear, and there is fluid leakage near the gearbox housing. Due to the frequent heavy loads, hill climbing, and long-distance operations of pickup trucks, the clutch system is frequently used, and the slave cylinder is one of the wearing parts.

Applicable models (Application)
This product is accurately adapted to the following models:
•2004 to present TOYOTA HILUX VII Pickup (_N1_, _N2_, _N3_)——commonly known as the Hilux Vigo series pickup truck in the industry

Market background: The Hilux seventh generation (Vigo) is Toyota's main pickup truck model in Southeast Asia, the Middle East, Africa and Oceania. It is equipped with 2KD-FTV, 1KD-FTV and other diesel engines and is widely used in agriculture, mining, logistics and off-road modification fields. The platform also spawned the Fortuner SUV and Innova MPV models during the same period. The three share some clutch hydraulic system components and have large market circulation. They are high-frequency inquiry categories in the Southeast Asian and African auto parts markets.

Core functions
•Receive hydraulic pressure: The hydraulic pressure transmitted from the master cylinder is converted into thrust here, driving the release fork action, which is the "last link" of the clutch release action.
•Sealing and leak-proof design: Built-in high-precision sealing components prevent brake fluid leakage, maintain system pressure stability for a long time, and adapt to frequent full-load conditions of pickup trucks.
•Original bore matching: The 20.64mm bore is consistent with the original vehicle calibration, and the thrust output meets the clutch system design requirements of the Hilux Vigo platform.
•Double-hole flange fixation: The installation structure adopts a 2-Φ8.9 double-hole design (Φ29.5/34), which accurately corresponds to the original vehicle gearbox housing installation position and is firmly positioned.
•Double M10×1.0 interface design: Both ends of the hydraulic pipeline have M10×1.0 thread specifications, which are convenient for connection with the main cylinder side pipeline and exhaust valve, and are easy to install.
•Cross-model sharing: This specification is also suitable for Innova MPV and other models derived from the same platform, making it easier for parts dealers to expand their sales scope.

What problem does this product solve for your customers?
Private label customers (Private Label/OBM)
•Support OEM/ODM OEM, packaging and labels can be customized according to brand requirements. Hilux Vigo is a very well-known pickup truck model in Southeast Asia and Africa. It can easily be recognized by local repair shops and fleet customers when paired with its own brand.
•The slave cylinder and the master cylinder are often purchased as a set. If you already have a master cylinder product line of the same platform, adding this slave cylinder can complete the set and increase the unit price.
•Provide complete technical information (OE part numbers, parameter tables, ISO certification documents) to support brand listing and qualification review.

Wholesale Distributor
•Hilux Vigo is one of the pickup trucks with the largest market share in Southeast Asia and Africa. It has high operating intensity, fast wear of the clutch system, and stable and continuous demand for slave cylinder replacement.
•It has been included as a standard cross-part number by international brands such as AISIN and BLUE PRINT, making it easier for your customers to query and compare in the system and improve the inquiry conversion rate.
•Fully inspected before leaving the factory, the sealing performance and dimensional accuracy meet the original factory requirements, effectively reducing the return and exchange rate.
•It is recommended to stock it with the clutch master cylinder, release bearing and other kits of the same platform, so as to provide customers with a one-stop clutch system maintenance solution.

Cost Optimization Customers (Cost Optimization)
•The specifications are consistent with the original parts and the price is more competitive, helping you to increase profit margins without affecting adaptability. It is especially suitable for the price-sensitive repair markets in Africa and Southeast Asia.
•ISO 9001 quality management system certification, the quality system is well documented and can be used as quality endorsement to downstream customers and importers.
•Support mixed box purchasing with other Hilux/Fortuner/Innova accessories on the same platform, and consolidate goods to reduce logistics unit costs.

Q1: What is the difference between the slave cylinder and the master cylinder? Which one should I buy?
A: The master cylinder (Master Cylinder) is installed near the cockpit pedal and is responsible for converting pedaling force into hydraulic pressure; the slave cylinder (Slave Cylinder) is installed on the gearbox housing and is responsible for receiving this pressure to push the separation fork. If the softness of the pedal is felt from the pedal, usually check the master cylinder first; if the gear shift is delayed or the gear is difficult to shift, the slave cylinder is more likely. It is recommended to judge based on actual fault symptoms or replace the entire kit number.

Q2: What is the difference between XUI4523A and Toyota original part 31470-0K020?
A: XUI4523A is a replacement part (OEM Equivalent) manufactured in accordance with the original OE specifications. The cylinder diameter, double-hole flange installation dimensions, and hydraulic interface threads are all consistent with the original parts and comply with ISO 9001 quality standards. The price is more competitive than original parts and the installation method is exactly the same.

Q3: Is this slave cylinder only suitable for Hilux?
A: This product is mainly suitable for Hilux VII Pickup (i.e. Hilux Vigo) from 2004 to present. Since this platform shares some clutch hydraulic system components with the Innova MPV of the same period, models with the same specifications can theoretically be used as a reference, but it is recommended to check the frame number or engine model before placing an order.

Q4: What should I pay attention to when installing?
A: After replacing the slave cylinder, the clutch hydraulic system must be vented according to specifications to ensure that there is no air in the pipeline. Otherwise, the pedal will become soft or the clutch will not be completely separated. It is recommended that a professional technician check the pedal stroke and separation effect after installation.
