AMS Evo X Clutch Master Cylinder Upgrade – 2008–2015 Mitsubishi Evolution X

Description

AMS Evo X Clutch Master Cylinder Upgrade – 2008–2015 Mitsubishi Evolution X

Firstly, BUY AMS Evo X Clutch Master Cylinder Upgrade for 2008–2015 Evo X GSR. Upgrade the clutch hydraulic system in your Mitsubishi Evolution X with the AMS Evo X Clutch Master Cylinder Upgrade. Designed for 2008–2015 Mitsubishi Evolution X GSR/USDM models, this AMS Performance kit replaces the factory plastic clutch master cylinder with a stronger OEM Mitsubishi Evo VIII/IX steel master cylinder using a precisely engineered adapter system. The complete kit is designed specifically for Evo X applications and carries AMS part number AMS.04.03.0002-1.

The factory Evo X clutch master cylinder can experience increased stress when an aftermarket clutch with higher clamping force is installed. AMS developed this upgrade around the OEM steel clutch master cylinder used on the Evo VIII/IX, adapting it to the Evo X firewall with a purpose-built aluminum adapter plate. AMS states that the conversion is designed to address failures associated with increased hydraulic pressure from aftermarket clutches and spirited driving.

Rather than simply replacing the original master cylinder with another factory-style Evo X unit, the AMS system changes the mounting arrangement and uses a stronger steel master cylinder. The result is a purpose-built clutch hydraulic upgrade for Evo X owners running upgraded clutches or looking for a more robust replacement solution.

Why Upgrade the Evo X Clutch Master Cylinder?

The clutch master cylinder is one of the key components in the Evo X hydraulic clutch system. It converts movement from the clutch pedal into hydraulic pressure, which is then transferred to the clutch slave cylinder.

When an Evolution X is equipped with a higher-clamping-force aftermarket clutch, the hydraulic system can be subjected to greater loads. AMS developed this conversion to replace the factory plastic master cylinder with the OEM steel unit from the Evo VIII/IX generation.

Firstly, the kit provides a stronger master-cylinder configuration by adapting the OEM Evo VIII/IX steel unit to the Evo X.

Secondly, the AMS adapter plate is specifically machined for the Evo X firewall. AMS states that its engineers used precision measurement equipment, including AutoCAD and a CMM arm, to develop the adapter for proper fitment.

Thirdly, the kit incorporates additional components designed for long-term durability, including a steel ball-cup link and nylon-coated stainless braided hydraulic line.

OEM Evo VIII/IX Steel Master Cylinder Conversion

One of the defining features of this product is the use of an OEM Mitsubishi Evo VIII/IX clutch master cylinder rather than the original plastic Evo X unit. The master cylinder is adapted to the Evo X using the AMS aluminum mounting plate.

This approach gives Evo X owners a purpose-built solution without requiring a completely custom hydraulic system. The kit arrives assembled with the OEM Evo VIII/IX master cylinder, according to AMS’s current product listing.

Adapter Plate and Firewall Sealing

The AMS adapter plate is manufactured from aluminum and features a gold-anodized finish. The mounting area is counter-bored to sit securely against the Evo X firewall.

AMS also incorporates a sealing foam ring around the mounting area. This helps keep moisture and dirt from entering the passenger compartment around the master-cylinder installation point.

The combination of the adapter plate and sealing system is important because the product is not simply a universal master-cylinder swap. It is specifically engineered to adapt the Evo VIII/IX component to the Evo X chassis.

Stainless Braided Hydraulic Line

The kit also uses a stainless-steel braided Teflon hydraulic line with a protective nylon coating. This design provides a more purpose-built hydraulic connection while helping protect the line against abrasion.

This is particularly useful for performance-oriented Evo X builds where the clutch hydraulic system may experience more demanding operating conditions than a completely stock vehicle.

Steel Ball-Cup Link

AMS includes a steel ball-cup link as part of the conversion system. The steel construction provides an additional durability-focused component at the clutch pedal connection.

This attention to the pedal-side connection is part of the overall AMS design rather than relying exclusively on the replacement master cylinder itself.
