Product Description
SmoothDrag CarbonTex Drag Washer Kit – 2015-2018 Calcutta Conquest 300US / 400US & 300HG
Upgrade the high-performance internals of your premium round reels with the SmoothDrag CarbonTex Drag Kit, precision-cut specifically for the 2015–2018 Shimano Calcutta Conquest 300US/401US and the Calcutta 300HG (and 400HG) series. These reels are designed for the high-torque demands of big-bait fishing; adding CarbonTex washers provides the silky-smooth engagement required to stop massive Musky, trophy Bass, or saltwater predators.
The "US" and "HG" series utilize a more advanced drag stack than older round reels. Replacing the factory washers with CarbonTex (#SDS102 / SDX1015 series) eliminates the "stick-slip" start-up inertia that can snap light braid or pull hooks during the initial, violent surge of a big fish.
Key Performance Benefits
-
Stutter-Free Startup: Virtually eliminates drag "chatter," ensuring a perfectly fluid line release even under the high-pressure settings (up to 18 lb+) used for glide baits and heavy jigs.
-
Extreme Heat Management: Engineered to handle the friction generated by Shimano’s high-speed "HG" gearing, preventing the drag from glazing or fading during long, blistering runs.
-
Hydrophobic Stability: Carbon fiber does not absorb moisture or swell, ensuring your drag settings remain consistent in heavy rain or salt spray.
-
X-Ship Compatibility: Sized specifically to fit the larger diameter main gears found in the 2015/2018 upgraded chassis.

This kit is a precision-cut, direct-fit upgrade for the internal drag stack. For exact part orientation, please consult the official PDF schematics at www.reelschematic.com.

Professional Maintenance & Lubrication
To achieve the legendary "silky" feel of a CarbonTex system and protect the Micromodule gearing of your Calcutta, proper lubrication is essential during installation:
-
Drag Surface Treatment: Apply a very thin, translucent coating of Cal’s Universal Drag Grease or Deuthlon Reel Grease to both sides of each CarbonTex washer. This specialized grease is engineered to stay on the carbon surface under extreme pressure, providing a waterproof barrier and preventing "chatter."
-
Mechanical Fluidity: Use Deuthlon Reel Oil on the spool bearings to ensure the reel operates with zero friction, maximizing your casting distance and the performance of the SVS Infinity braking system.
Installation Tip: The 2015/18 series features an "Exciting Drag Sound" (clicker) mechanism. When replacing washers, ensure the small spring and pin components are properly seated within the main gear to maintain your audible drag alert.
