It's that small hydraulic cylinder in a manual transmission pickup truck 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; in severe cases, you won't be able to shift at all. For work-oriented pickups like the Rodeo, Campo, and Brava, a failed clutch slave cylinder means the vehicle will be grounded for both hauling and working, resulting in significant financial losses.

Specific Applications:
1985-1988 Holden Rodeo Pickup KB (First Generation)
1989-1990 Isuzu Campo KB 2.2 (TFS)
1994-1999 Isuzu TFR/TFS Pickup TF_ 2.3
1991-1996 Opel Campo TF0, TF1 2.3 (TFR16)
1991-1996 Opel Campo TF0, TF1 2.3 Four-Wheel Drive Version (TFS16)
1991-1996 Vauxhall Brava Pickup TF0, TF1) 2.3 (TFR16)

Supplementary Notes: These models are all developed based on the Isuzu TF platform, designed by Isuzu Japan, and manufactured in Southeast Asian factories in Thailand, Indonesia, and the Philippines. They are later rebadged and sold by Holden (Australia), Opel (Europe), and Vauxhall (UK).

The production cycle spanned from 1985 to 1999, covering nearly 15 years, with huge cumulative production and sales, especially in major pickup truck markets such as Australia, Southeast Asia, the Middle East, and Africa.

The Holden Rodeo is a national-level utility vehicle in Australia and New Zealand, with a very large ownership base; the Opel Campo and Vauxhall Brava hold a place in the European commercial pickup truck market.

These models are currently 25-40 years old, but are still widely used as utility vehicles. The clutch driven cylinder is a frequently replaced part, resulting in continuous after-sales demand.

Core Function: Hydraulic Pressure-driven end-of-line execution: Receives hydraulic pressure from the clutch master cylinder, precisely pushes the release bearing, and completes the clutch disengagement action.

Sealing and leak-proof protection: Employs high-quality rubber seals to prevent hydraulic oil leakage, ensuring long-term stable system pressure and adapting to the harsh working conditions of pickup trucks.
Resistant to mud and corrosion: The sealing structure features a dust cover design to prevent road dust and mud intrusion, extending service life in harsh environments such as construction sites and farms.
High load durability: High precision piston-cylinder fit, withstanding high-intensity usage scenarios such as heavy-load starts and frequent semi-clutching of pickup trucks.
Ready-to-use compatibility: Mounting holes, pipe threads, and push rod lengths are all manufactured according to Isuzu TF platform original factory standards, requiring no modifications.
Multi-brand compatibility and interchangeability: One product model covers pickup trucks from four brands—Isuzu, Holden, Opel, and Vauxhall—on the same platform.

What problems can this XUI4103A solve for your overseas customers? Fifteen OE numbers combined into one, simplifying inventory: Fifteen original equipment manufacturer (OEM) numbers correspond to one product model, reducing SKU count by over 90%, significantly simplifying inventory management, and dramatically improving capital turnover efficiency.
Four brand coverage, extremely wide sales reach: One model simultaneously covers pickup trucks from four brands—Isuzu, Holden, Opel, and Vauxhall—on the same platform. Customers do not need to stock separate inventory for each brand; one inventory serves four customer groups.
Classic pickup truck after-sales service needs: These models are still used intensively in harsh environments such as Australian farms, Southeast Asian construction sites, and Middle Eastern deserts as work vehicles. The clutch driven cylinder is a frequently replaced part, resulting in stable and continuous order demand.
Original parts are expensive and have long lead times: Isuzu original parts are imported from Japan or Thailand, with high unit prices and lead times typically 6-12 weeks. Some older OEM numbers are also discontinued. XUI4103A offers equivalent OE quality at a 25%-45% lower price, helping customers rebuild price competitiveness. Own-brand premium: Supports neutral packaging and customized brand packaging, helping customers escape the predicament of "selling someone else's brand" and establish long-term brand assets in the pickup truck parts market.

Addressing customer pain points:
Complex OE numbers leading to chaotic inventory: Fifteen OE numbers belong to four brands—Isuzu, Holden, Opel, and Vauxhall—with different numbering rules, often leaving customers unsure which number to prepare. XUI4103A covers all numbers with a single model, completely solving this problem.
Original parts out of stock or limited supply: Some older OE numbers from 1985-1990s are discontinued or have limited supply, leaving customers with no stock to sell. We maintain stable production, ensuring supply chain security.
Inconsistent quality of aftermarket parts: Low-priced alternatives on the market often have problems such as poor sealing, cylinder block sand holes and leaks, and pushrod length deviations, quickly failing under heavy-duty pickup truck conditions. We use OE-grade materials and precision machining processes, keeping the return rate below 1%.
Installation compatibility is not difficult: Manufactured strictly according to the original Isuzu TF platform installation dimensions and thread specifications, the mounting bracket hole positions (2-Φ10.8), push rod length, and M10×1.0 pipe interface are 100% matched, ensuring zero installation difficulties for technicians.
Durability under harsh working conditions is insufficient: Pickups are used in environments such as construction sites, farms, and deserts, where there is high dust, large temperature differences, and strong vibration. Our seals use oil-resistant and aging-resistant materials, and the dust cover design prevents mud and sand intrusion, ensuring long-term reliability.

Q1: Why can XUI4103A be compatible with four brands simultaneously: Isuzu, Holden, Opel, and Vauxhall?
A: These models are all developed based on the Isuzu TF platform and manufactured by Isuzu in its Southeast Asian factories. Holden, Opel, and Vauxhall are rebranded and sold. Clutch hydraulic system components are completely interchangeable, therefore one product model can cover four brands.

Q2: Can all fifteen OE numbers be replaced with XUI4103A?
A: Yes. 8-94319-314-1, 8-94146-647-0, 8-94319-310-0, 8-94319-314-0, 8-94389-192-0, 8-94389-193-0, 8-94432-073-1, 8-94474-122-0/1, 8-97039-706-0, 94389192, 94474122, 97039706, 4301563, and 6 79 341 are all serial numbers for the same specification clutch driven cylinder under different years, brands, or regional markets. Their installation dimensions and hydraulic performance are not substantially different.
