Round Reel Perfection: Smoothdrag Carbontex Drag Kit for Daiwa Millionaire CV-Z/X & Luna 300
The Daiwa Millionaire CV-Z, CV-X, and Luna 300 series represent the pinnacle of Daiwa's round-profile baitcasting engineering. Known for their "tank-like" durability, these reels are favorites for swimbaiting, musky fishing, and light saltwater duty. However, the factory drag washers can develop "stiction"—that jerky, uneven release—especially after a few seasons of heavy use.
The Smoothdrag Millionaire (5) Carbontex Drag Kit (often referenced as Part #SDD13) is the definitive performance upgrade. By replacing the original 5-washer factory stack with high-density, cross-weave Carbontex, you achieve a level of smoothness and stopping power that matches the precision of the reel's internal gears.
Why Upgrade Your Millionaire or Luna 300?
-
Eliminate "Stick-Slip": Carbontex provides zero start-up inertia. This ensures the drag engages instantly and stays perfectly linear, protecting your knots and preventing snapped lines when a fish first bolts.
-
Refined Precision: These reels are often used for technical fishing with specialized lures. Carbontex allows for granular, micro-adjustments to the drag star, giving you total control over the fight.
-
Superior Heat Management: Big fish and long runs generate significant friction heat. Carbon fiber handles these temperatures far better than factory composites, preventing drag "fade" or glazing.
-
Saltwater Integrity: Unlike original fiber washers that can absorb moisture and become "mushy" or inconsistent, Carbontex is virtually impervious to the elements and won't rot or compress.
Comprehensive Fitment & Compatibility
This kit is precision-lapped to fit the internal gear stacks of Daiwa’s premier 300-sized round baitcasters.

Technical Note: The Millionaire 300 series uses a 5-washer stack. Because these reels are built to extremely tight tolerances, maintaining the exact sequence of the stainless steel keyed and eared washers is vital for proper gear alignment.

Professional Installation & Lubrication Protocol
For these precision round reels, we strongly recommend a "wet drag" setup to achieve that signature "buttery" feel and provide a waterproof barrier:
-
Cal’s Universal Drag Grease: Apply an ultra-thin, translucent coating of Cal’s Grease (Tan or Purple) to both sides of each Carbontex washer. This specialized PTFE grease prevents "chatter" and ensures the drag remains consistent even in heavy salt spray.
-
Drive Washer Inspection: Check your original stainless steel drive washers (the metal ones between the carbon). If they show any signs of "glassy" buildup or salt pitting, polish them with 0000 grade steel wool to a mirror finish.
-
Smooth Ground Metal Washers: For the ultimate performance, some anglers pair this kit with Smooth Drag Ground Metal Washers (Gr2), which are lapped to a flatness unreachable by factory stamped parts.
-
Pinion & Gear Care: While the side plate is open, apply a light coating of Deuthlon Reel Grease to the main gear and pinion to keep the retrieve effortless under load.
