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 K68-539-00 is a reverse lockout solenoid designed for trailer disc brake actuators, enabling automatic free backing operation when reversing. Unlike drum brakes, disc brakes generate full braking power in reverse, making this solenoid essential for actuators without a built-in reverse lockout lever or switch.

Key Features:

  • Flow blocking style solenoid valve for older model disc brake actuators
  • 12-volt operation connects directly to tow vehicle backup light circuit
  • Automatic brake lockout eliminates manual switching
  • Thread size: 3/16" inverted flare (IF) x 1/8" male pipe (MP)
  • Compatible with both disc and drum brake systems
  • Can be wired independently or adapted to trailer wire harness with 5-flat plug

This solenoid installs at the actuator before the disc brake installation and requires only one electrical connection between the solenoid and the vehicle's backup light. When the vehicle shifts into reverse, the solenoid automatically allows the trailer to freewheel, providing convenient operation without leaving the cab. Also known as Tie Down Engineering part number 81103.

Simple and quick

good pricing, free shipping and had the parts I needed in stock. Nice Job!

Happy you still had the part after all these years! Thanks

This belt is hard to find for my truck you had it and ordering was easy thank you so much
