Ultimate Smoothness: Smoothdrag Carbontex Drag Kit (J31-3601) for Daiwa BG 4500 & 5000
Stop letting "sticky" factory drags cost you trophy fish. The Smoothdrag Carbontex Drag Kit (Part #J31-3601) is the definitive performance upgrade for the modern Daiwa BG 4500 and 5000 series. Designed to replace the original factory felt washers, this 3-washer kit utilizes high-density, cross-weave carbon fiber to provide a silky-smooth transition and massive stopping power.
The Daiwa BG is a legendary workhorse, but its standard felt drag system can stutter or "stick" under the heat of a long run. By upgrading to Carbontex, you ensure that your drag engages with zero start-up inertia, protecting your knots and light leaders during that critical first surge.
Why Upgrade to the J31-3601 Carbontex Kit?
-
Eliminate "Stick-Slip": Experience a perfectly linear line release. No more jerky movements that lead to snapped lines.
-
Superior Heat Management: Carbon fiber maintains its friction coefficient even during the high-friction heat generated by big saltwater game.
-
Increased Stopping Power: Gain a higher maximum drag ceiling for "lock-down" power while retaining precision adjustability for finesse work.
-
Exceptional Durability: Unlike felt washers that compress, rot, or glaze over, Carbontex is virtually wear-proof and impervious to the elements.
-
Saltwater Ready: These washers are designed to thrive in harsh marine environments, ensuring reliability season after season.
Detailed Fitment & Compatibility
This kit is precision-lapped to fit the internal drag stack of Daiwa’s modern heavy-duty BG series (Black Gold).
This part fits the following Daiwa Spinning Reel Models:
-
BG 4500 (Modern Black/Gold series)
-
BG 5000 (Modern Black/Gold series)
Technical Note: Proper washer sequencing is vital for the performance of the ATD (Automatic Tournament Drag) system housing. To verify 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 to provide the ultimate barrier against moisture and salt, we strongly recommend a "wet" drag setup during installation:
-
Deuthlon Reel Grease: Apply an ultra-thin, translucent coating of Deuthlon Reel Grease to each side of the Carbontex washers. This specialized PTFE-based grease prevents "chatter" and ensures the drag remains consistent even if the reel gets splashed.
-
Deuthlon Reel Oil: While the spool is 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 rotation and maximizing casting efficiency.
