Finesse with Muscle: Smoothdrag Carbontex Drag Kit (373-3701) for Daiwa BG & GS Series
If your classic Daiwa feels a little "stuttery" when a solid fish decides to take a run, it’s not the reel's fault—it’s the old-school felt washers. The Smoothdrag Carbontex Drag Kit (Part #373-3701) is the definitive performance upgrade for the legendary Daiwa BG13, BG15, and GS15 spinning reels.
By swapping out the factory felt for high-density, cross-weave Carbontex, you effectively eliminate "stick-slip"—that jerky hesitation that leads to snapped leaders and pulled hooks. This kit provides a silky-smooth transition from a standstill to a full run, ensuring your drag remains consistent whether you're finesse fishing for smallmouth or wrestling a stubborn inshore redfish.
Why Upgrade Your Small-Frame Daiwa?
-
Zero Start-Up Inertia: The drag engages instantly and smoothly, protecting light lines during that critical first surge.
-
Superior Thermal Stability: Carbon fiber handles the friction-induced heat of long runs without "glazing" or losing its stopping power.
-
Increased Max Drag: Experience a higher top-end drag ceiling while maintaining the ability to fine-tune lower settings for delicate presentations.
-
Unmatched Durability: Unlike felt washers that compress, rot, or degrade over time, Carbontex is virtually wear-proof and impervious to moisture and saltwater.
-
Precision Thickness: Specifically calibrated for the 373-3701 gear stack to ensure your drag knob retains its full range of adjustment.
Detailed Fitment & Compatibility
This kit is precision-lapped to fit the internal drag stack of Daiwa’s iconic small-to-mid-sized heavy-duty spinning reels.
Fits the following Daiwa Spinning Reel Models:
-
Black Gold (BG) Series: BG13, BG15
-
GS Series: GS15
Technical Note: While these reels are built like tanks, internal configurations can vary slightly by generation. To confirm your specific internal parts layout, you can view and download high-resolution, exploded-view PDF schematics at www.reelschematic.com.
Professional Installation & Lubrication
For a truly "super-tuned" feel and maximum protection against the elements, we strongly recommend a "wet" drag setup during installation:
-
Deuthlon Reel Grease: Apply a very thin, translucent coating of Deuthlon Reel Grease to each side of the Carbontex washers. This specialized PTFE-based grease prevents "chatter" and creates a waterproof barrier that is vital for harsh environments.
-
Deuthlon Reel Oil: While you have the spool off, apply a drop of Deuthlon Reel Oil to the main shaft and the line roller assembly. Its ultra-low friction formula is essential for maintaining smooth line retrieve and maximizing casting distance.
