Description
When you're finishing a premium hydraulic clutch system, the reservoir is where function meets form - and MDL's 2100 Series delivers both without compromise. This is the same reservoir that comes standard with every MDL Stealth Series Master Cylinder System, now available as a standalone upgrade for builders who demand show-quality components throughout their drivetrain.
The engineering starts with the smallest footprint in the automotive industry, achieved through MDL's exclusive in-house design that maximizes fluid capacity while minimizing installation constraints. The built-in -4AN fitting is machined as part of the body - not a threaded insert that can leak or fail - ensuring a permanent, leak-proof connection. The quick-release O-ring sealing surface means cap removal becomes a simple operation instead of wrestling with threaded fittings.
The one-piece billet aluminum construction uses thicker wall sections than typical aftermarket reservoirs, preventing body distortion when mounting brackets are tightened. Twin set screws lock the reservoir position permanently, while the exclusive COFFEY filter prevents fluid splash during hard acceleration or cornering. The vented cap design features side top vents to prevent water entry while working with any master cylinder type, making this reservoir truly universal for hydraulic clutch applications.
Available with optional 12-inch -4AN braided line and matching billet spacer block. A -4AN to 1/4-inch black barbed fitting is also available for rubber hose applications. If you have an existing -4AN master cylinder fitting in place, refer to Item# MD-960-2100-CH for the cap-and-hose-only version. Also available in black anodized finish. Made in the USA.
