The High-Speed Classic Upgrade: Smoothdrag Carbontex Drag Kit for Penn 113H (4/0)
The Penn Special Senator 113H (Red Side Plate) is arguably the most famous offshore reel ever produced. While the black-sided 113 was built for slow-cranking power, the 113H introduced a higher gear ratio and a more robust drag stack for the modern era. However, factory HT-100 washers—while revolutionary—can become "grabby" or glaze over after seasons of high-speed trolling or heavy bottom fishing.
The Smoothdrag Carbontex Kit for the 113H is the gold standard for "super-tuning" this 4/0 platform. By replacing the original stack with high-density, cross-weave carbon fiber, you achieve zero start-up inertia. This ensures that when a hard-pulling Wahoo, Yellowtail, or bottom-dwelling Grouper surges, the drag engages instantly and stays perfectly smooth, protecting your knots and heavy braided or monofilament lines.
Why Upgrade Your 113H or Pro Gear to Carbontex?
-
Eliminate "Stick-Slip": The 113H is often used for high-pressure fishing. Carbontex removes the jerky hesitation common in aged factory stacks, providing a perfectly linear drag curve.
-
Thermal Stability: Fighting large gamefish generates intense friction heat. Carbon fiber handles these temperatures far better than standard composites, preventing drag "fade" or glazing during long runs.
-
Cross-Platform Performance: This kit is famous among "hot-rod" reel builders because it also fits several high-end Pro Gear and Pacifica models, bringing modern drag technology to those precision frames.
-
Modern Braid Resilience: If you have converted your 113H to heavy braid, Carbontex provides the consistent, non-compressible surface required to maintain high lockdown pressure without the "mushy" feel.
Comprehensive Fitment & Compatibility
This kit is precision-lapped to fit the internal main gear stacks of the "High Speed" 4/0 Senator and its boutique derivatives.
| Brand | Compatible Models |
| Penn | Special Senator 113H (4/0 Red Side Plate only) |
| Pro Gear | 440, 441, 454 Yellowtail (YT) Special, 541, 545 |

⚠️ CRITICAL FITMENT NOTE: This kit is designed specifically for the Red Side Plate (High Speed) 113H. It WILL NOT FIT the Black Side Plate (standard speed) 113. If you have a black-sided 113, you require the "5-Stack Conversion Kit" instead.
Professional Installation & Lubrication Protocol
For mid-to-large conventional reels, a "wet drag" setup is the professional standard for maximum smoothness and internal protection:
-
Cal’s Universal Drag Grease: Apply an ultra-thin, translucent coating of Cal’s Grease (Tan) to both sides of each Carbontex washer. This specialized PTFE grease prevents "chatter" and creates a waterproof seal that protects your stainless steel metal plates from salt pitting.
-
Metal Washer Restoration: Check your stainless steel drive washers (the metal ones between the carbon). Look for any signs of "bluing" from heat or salt scoring. Polish them with 0000 grade steel wool to a mirror finish.
-
Gear Sleeve Inspection: Since you are maximizing your drag potential, ensure your gear sleeve is in good shape. Many 113H users upgrade to a Stainless Steel Gear Sleeve to prevent the rounding of flats under high drag pressure.
-
Main Gear Lube: Apply a fresh coating of Deuthlon Reel Grease to the main gear teeth to keep the retrieve effortless under the high torque of a big fight.
