The Heavy-Duty Conversion: Smoothdrag 113 4/0 "5-Stack" Carbontex Kit
The Penn Senator 113 (Black Side Plates) is the quintessential "tank" of the trolling world. However, these original black-side models (the non-high speed versions) were often equipped with a thinner, less powerful 3-washer drag stack. This Smoothdrag 5-Stack Conversion Kit is the gold standard for "hot-rodding" these classic reels, effectively increasing the drag surface area to provide more stopping power and modern smoothness.
By upgrading to this 6-Carbontex/5-Metal washer configuration, you replace the antiquated factory material with high-density, cross-weave carbon fiber. This setup provides zero start-up inertia, ensuring that when a heavy bottom-dweller or offshore pelagic bolts, the drag engages instantly without the "jerk" that snaps heavy mono or braid.
Why Upgrade to the 5-Stack Carbontex System?
-
Increased Surface Area: By moving from a standard stack to a 5-stack (using 6 carbon washers including the under-gear washer), you significantly increase the friction surface. This results in higher maximum drag and better heat dissipation.
-
Eliminate "Stick-Slip": Vintage Penn washers are notorious for "grabbing" before they slip. Carbontex provides a perfectly linear drag curve, protecting your knots and gears.
-
Thermal Stability: Offshore battles generate intense friction heat. Carbon fiber handles these temperatures far better than old-school fiber or asbestos-style washers, preventing drag "fade."
-
Saltwater Resilience: These reels live in the salt. Carbontex is virtually impervious to moisture and won't rot or become "mushy" like original factory discs.
Comprehensive Fitment & Compatibility
This specific kit is precision-lapped to fit the internal gear stacks of Penn’s legacy mid-to-large frame conventional reels.
| Series | Compatible Models |
| Senator | 111 (2/0), 112 (3/0 - No "H" models), 113 (4/0 - Black Sides only) |
| Long Beach | 66, 67, 68 |
| Special Purpose | 267, 268 |
⚠️ Technical Note: This kit is designed for the standard (Black Side Plate) models. It is not compatible with the "H" or "HSP" (Red Side Plate) High-Speed Senators, which utilize a different gear and washer diameter. This kit includes the metal washers because the 5-stack conversion requires a specific metal-to-carbon ratio to fit within the original main gear.
Professional Installation & Lubrication Protocol
For heavy conventional reels, a "wet drag" setup is the professional standard for maximum protection and longevity:
-
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 new metal washers from salt pitting.
-
Metal Washer Sequence: Follow the "Sandwich" method: Metal, Carbon, Metal, Carbon. Ensure the "Eared" metal washers are seated correctly in the main gear slots and the "Keyed" washers are aligned with the gear sleeve flats.
-
Gear Sleeve Inspection: Since you are increasing the drag pressure, check your brass or stainless gear sleeve for any rounding of the flats. If the flats are worn, the drag may slip or feel "spongy."
-
Main Gear Lube: Apply a fresh coating of Deuthlon Reel Grease to the main gear teeth to keep the retrieve smooth under the high torque of a big fight.
