Say goodbye to the constant mess, expense, and hassle of traditional fifth wheel grease. The Buyers Products FWD12 12-Inch Poly Fifth Wheel Lube Disc is the modern solution for a cleaner, more efficient, and lower-maintenance connection between your tractor and trailer. Engineered from exceptionally durable high-density polyethylene, this lube disc creates a self-lubricating, low-friction surface that protects your equipment from premature wear and tear. Stop wasting time and money on messy grease applications and clean-ups, and upgrade to a smarter, cleaner, and more reliable system that keeps your rig and your hands clean, trip after trip.
The core benefit of the FWD12 lies in its advanced material and simple design. The high-density polyethylene (HDPE) is specifically chosen for its incredible toughness, low coefficient of friction, and resistance to weather, road salts, and chemicals. Unlike grease, which can capture dirt, sand, and other abrasive debris that grinds away at your fifth wheel plate, this poly disc provides a solid, clean barrier. This not only extends the service life of your valuable equipment but also ensures smoother, more consistent articulation when turning. This innovative product is a testament to the quality and engineering you expect from a leading brand like Buyers Products, designed to withstand the harsh demands of the commercial trucking industry.
Integrating the FWD12 into your fleet’s maintenance routine translates directly to operational savings. By eliminating the recurring cost of grease and the labor hours spent on application and cleanup, you reduce your total cost of ownership. The simple installation process—just drop it over the kingpin—means vehicles spend less time in the shop and more time on the road earning revenue. This lube disc is an essential upgrade for fleet managers, owner-operators, and maintenance technicians looking to streamline operations, improve safety, and maintain a more professional and clean appearance for their equipment.
