41605-3S000 Eyelet Pushrod Clutch Master Cylinder

Application
HYUNDAI Sonata VI (YF) (Year of Construction 01.2009 - 12.2015)
KIA Optima / K5 (TF) (Year of Construction 01.2010 - 04.2017)

Core Function
The job here is the same basic principle as any clutch master cylinder, with a few specific details worth noting:
1. The eyelet pushrod connects to the pedal linkage through a pin, transferring foot pressure into the internal piston
2. The piston moves fluid out through the angled side port toward the slave cylinder
3. A return spring pulls the piston back once pedal pressure is released, resetting the system for the next stroke
4. The flange and gasket at the mounting base keep the unit sealed against the firewall, preventing fluid or air leaks at the connection point
Because the pushrod shape is fixed to match a pin-through-eyelet linkage, this variant isn't interchangeable with fork-end versions used on other platforms, which is exactly why getting this detail right matters before placing an order.

Purchasing Motivation
Buyers sourcing this part tend to have run into a specific problem before: ordering a clutch master cylinder that technically matches the OE number range but arrives with the wrong pushrod end, leaving the part unusable without modification.
Correct linkage match from the start — the 41605-3S000 Eyelet Pushrod Clutch Master Cylinder is sourced by buyers who've already learned that pushrod shape matters as much as bore size or mounting pattern
Fewer returns tied to fitment issues — a pushrod that doesn't match the pedal linkage is one of the more common reasons parts get sent back, and getting this right the first time saves both the buyer and the supplier that back-and-forth
Repeat sourcing reliability — distributors managing stock for a specific vehicle platform need a supplier who delivers the same spec consistently across multiple orders

OEM/ODM Customization
Buyers bringing the 41605-3S000 Eyelet Pushrod Clutch Master Cylinder into their own catalog have some room to adjust the packaging side of things:
1. Packaging options including blister packs, tube boxes, header cards, and PDQ display units
2. Private labeling for buyers who want their own branding rather than standard export packaging
3. A 40-foot container typically ships within about 20 working days, giving buyers a reasonable window to plan restocking
Buyers with a specific packaging format or branding requirement in mind are better off working through the details directly, since the right setup depends on where the part is headed — retail shelf or bulk distribution.
