Manufacturer

Dexter Marine Products

<p>Since 1960, Dexter has been the leading manufacturer of boat trailer axles, actuators, brakes, and other marine components. With over six decades of engineering excellence, Dexter Marine Products has earned its reputation as the trusted choice for boat trailer owners and OEM manufacturers who demand reliability in the harshest marine environments. Over the past 50 years, OEMs have installed more than 45 million Dexter Axles, a testament to the brand's commitment to quality and innovation.</p><h3>Engineering Excellence for Marine Applications</h3><p>What sets Dexter Marine Products apart is their specialized focus on the unique challenges faced by boat trailers. Unlike standard utility trailers, marine trailers regularly encounter saltwater exposure, frequent submersion, and corrosive conditions that can quickly deteriorate inferior components. Dexter's engineering team designs every product—from torsion axles to hydraulic brake systems—with these demanding conditions in mind, incorporating galvanized finishes, advanced sealing technologies, and corrosion-resistant materials throughout their product line.</p><p>The brand's dedication to innovation extends beyond materials. Their SuperLube lubrication system allows bearing maintenance without hub removal, while their Eliminator torsion axles feature removable spindles that simplify repairs and reduce downtime. These practical engineering solutions reflect Dexter's deep understanding of what trailer owners actually need on the water.</p><h3>Comprehensive Product Range</h3><p>Dexter's <a href="/12891-dexter-marine-products-hubs-200550">hubs</a> represent a critical connection point between axle and wheel, engineered with precision bearing races and galvanized construction to resist the constant moisture exposure that boat trailers endure. Their hub designs incorporate features like EZ-Lube fittings that make routine maintenance straightforward for owners who want to protect their investment.</p><p>The <a href="/12891-dexter-marine-products-brakes-brake-parts-200202">brakes and brake parts</a> lineup includes both drum and disc brake systems specifically calibrated for marine trailer applications. Dexter's Nev-R-Adjust brake technology eliminates the need for manual adjustment, automatically compensating for wear to maintain consistent stopping power throughout the brake's service life—a crucial safety feature when launching or retrieving valuable watercraft.</p><p>For hydraulic braking systems, Dexter's <a href="/12891-dexter-marine-products-brake-actuators-200201">brake actuators</a> provide the mechanical advantage needed to safely control trailer weight during highway travel and boat ramp maneuvers. These surge brake actuators activate proportionally to deceleration forces, delivering smooth, controlled braking without requiring electronic brake controllers.</p><p>Protecting wheel bearings from water intrusion is critical for marine trailers, and Dexter's <a href="/12891-dexter-marine-products-bearing-protectors-seals-bearings-200154">bearing protectors, seals, and bearings</a> create multiple barriers against moisture and contamination. From the comprehensive <a href="/12891-dexter-marine-products-trailer-parts-accessories-201094">trailer parts and accessories</a> catalog, boat owners can find every component needed to maintain, repair, or upgrade their trailer systems with confidence in Dexter's proven durability.</p><h3>American Manufacturing and Distribution</h3><p>American made Dexter products are manufactured in fully automated facilities. Lean, green and clean manufacturing processes increase efficiency, ensure accuracy, recycle waste, and keep costs down. This commitment to domestic production ensures consistent quality control and supports the rigorous testing protocols that have made Dexter the preferred choice for major boat trailer manufacturers nationwide. With the largest distribution network in North America, replacement parts and service support are readily available when and where trailer owners need them most.</p>

Product Details

The Dexter K23-451-00 is a complete 12-1/4" x 3-3/8" electric trailer brake assembly designed for right-hand (passenger side) mounting on 9,000 to 10,000 lb capacity trailer axles. This genuine Dexter brake assembly features forward self-adjusting (FSA) technology that automatically adjusts the brakes during both forward and reverse stops, virtually eliminating the need for manual adjustments.

Key Features:

  • Complete electric brake assembly with 12-1/4" diameter x 3-3/8" width
  • Forward Self-Adjusting (FSA) feature adjusts brakes automatically during use
  • Right-hand (passenger side) configuration
  • Rated for 10,000 lbs maximum capacity per pair
  • Mounts to 7-hole axle brake flange with cast spider design
  • Pre-wired with yellow wire magnet for easy installation
  • Made in USA by Dexter Axle

The self-adjusting mechanism works by automatically rotating the screw assembly at the bottom of the brake when lining wear creates sufficient gap between the shoes and drum surface. This action expands the distance between the shoes and closes the gap to maintain optimal braking performance. Designed for general duty applications on utility trailers, dump trailers, livestock trailers, and equipment trailers with 16" to 17.5" wheels.

Specifications:

  • Brake Size: 12-1/4" x 3-3/8" (12.25" x 3.375")
  • Mounting Pattern: 7-bolt flange
  • Side: Right Hand (RH) - Passenger Side
  • Capacity: 9,000-10,000 lbs
  • Magnet Wire: Yellow
  • Application: General Duty (GD) Forward Self-Adjusting

Replaces Dexter part numbers 023-451-00 and 23-451. Pairs with K23-450-00 left-hand brake assembly for complete axle setup. Works with Dexter brake drum 009-123-01 and oil seal 010-051-02.
