The BX88206 lubricant is designed to address the specific needs of these articulating arms, ensuring the release triggers remain snappy and reliable. By using this product, owners prevent the dreaded “sticking” that often occurs when a tow bar has sat idle for a few months.
The product is exceptionally effective at displacing moisture, which is critical for those traveling through coastal regions or humid climates. Unlike heavier oils, this spray applies cleanly and does not form a gummy mess that traps sand. It is a targeted maintenance tool designed for ease of use in a parking lot or a driveway.
Anyone running a Blue Ox setup should have a canister of this tucked away in their gear bay. It is not intended for heavy-duty load bearing, but rather for maintaining the smooth mechanical operation of moving parts. Stick with this specific product to ensure your release handles continue to function with a simple flick of the wrist.
Boeshield T-9 Lubricant: Best Corrosion Protection
Originally developed for the aerospace industry, Boeshield T-9 is arguably the most robust anti-corrosion barrier available for outdoor equipment. It works by forming a waxy, waterproof film that seals metal surfaces against the relentless assault of road salt and rain. For those who store their rigs in open environments, this is the most reliable way to prevent oxidation.
The magic of Boeshield lies in its ability to penetrate deep into joints, dry out, and then leave behind a protective coating that lasts for months. It is significantly more durable than standard light oils, which tend to wash away after a few hundred miles in the rain. This is a heavy-duty solution for those who tow in harsh conditions.
While it is slightly tackier than dry silicones, the trade-off for superior metal protection is worth it. If you tow through regions with high snow, salt, or mud, apply this to the exposed steel shafts of your tow bar. It effectively turns a maintenance task into a long-term defense strategy for your equipment.
CRC Power Lube w/ PTFE: Top Value Performance
Polytetrafluoroethylene, commonly known as PTFE, is a game-changer when it comes to reducing friction in metal-to-metal contact points. CRC Power Lube uses this additive to create a high-performance, non-stick surface on your tow bar arms. It is a versatile, high-value product that bridges the gap between basic cleaning and high-end mechanical lubrication.
Because it leaves behind a thin, dry film, it is less likely to collect road dust compared to traditional greases. The spray nozzle is easy to control, allowing for precise application directly into the crevices of the tow bar hinges. It offers a smooth, reliable release that feels professional without the premium price tag.
For the cost-conscious traveler who wants a high-performance result, CRC is an excellent choice. It provides enough protection for standard towing applications while being affordable enough to use generously. This is a reliable, no-nonsense option that delivers consistent results every time.
DuPont Teflon Silicone: Best for Wet Environments
Silicone-based lubricants are essential for environments where water intrusion is the primary threat to equipment health. The DuPont Teflon Silicone spray excels in these conditions because it is hydrophobic and doesn’t break down when exposed to heavy precipitation. It provides a slick, slippery surface that allows sliding components to move with minimal resistance.
The inclusion of Teflon particles provides an extra layer of protection, reducing wear on the metal surfaces during the constant vibration of transit. It remains stable across a wide range of temperatures, meaning the lubrication won’t turn into a viscous sludge in the winter or evaporate in the scorching summer heat. It is a highly effective, clean-drying formula.
This product is highly recommended for those who frequently camp in the Pacific Northwest or other damp, rainy climates. If you have noticed your tow bar arms dragging or catching during setup, this will provide the necessary slip to restore smooth operation. It is an essential item for anyone who doesn’t want their gear hampered by the weather.
WD-40 Specialist Silicone: Easiest to Find
Sometimes the best tool is the one available at the local hardware store when you are mid-trip and realize your tow bar is sticking. The WD-40 Specialist Silicone is a reliable, widely accessible option that gets the job done without fuss. It is a true dry lubricant that leaves no residue, making it ideal for components that shouldn’t attract road grit.
While it lacks the specialized heavy-duty anti-corrosion additives of products like Boeshield, it is perfectly adequate for keeping release handles and pivot points moving freely. It is essentially a high-quality maintenance spray that functions exactly as expected. For the casual RVer who just needs to keep things functional, it is more than sufficient.
Do not confuse this with the standard blue-can WD-40, which is a penetrant and not a long-term lubricant. Always reach for the “Specialist” silicone version when dealing with tow bar hardware to ensure you aren’t actually stripping away necessary grease. It is a convenient, effective, and reliable choice for general maintenance.
Why Proper Lubrication Is Not Optional
Many believe that tow bars are “set it and forget it” equipment, but this is a dangerous oversight. These devices are subjected to thousands of pounds of tension and constant road vibration, which inevitably breaks down factory coatings. Without a consistent layer of lubrication, metal-on-metal friction leads to wear, galling, and eventual mechanical failure.
Neglecting your tow bar can lead to a “seized” condition, where the release mechanisms become impossible to engage by hand. This forces travelers to resort to hammers or brute force, which often bends expensive components and compromises structural integrity. A simple, regular lubrication routine avoids these high-stakes frustrations entirely.
Furthermore, lubrication is your primary defense against rust. Tow bars spend their entire lives exposed to road salt, standing water, and flying gravel. Once rust penetrates the inner sleeves of a tow bar, the unit loses its ability to slide freely, rendering the entire system unreliable during an emergency or quick unhitching.
How to Properly Clean and Lube Your Tow Bar
The secret to a long-lasting tow bar is cleaning it before adding fresh lubricant. Start by using a clean rag to wipe down the arms, specifically removing any old, grit-filled grease that has collected road dust. If there is heavy caking, use a mild degreaser, but ensure the surface is completely dry before moving to the next step.
Once clean, extend the tow bar arms to their maximum length. Apply your chosen lubricant sparingly to the sliding surfaces, focusing on the points where the inner and outer shafts overlap. Cycle the arms in and out a few times to distribute the lubricant evenly across the entire surface area.
After cycling, wipe away any excess lubricant that has pooled on the exterior. Excess grease is a magnet for dirt, which creates an abrasive paste that actually accelerates wear over time. The goal is to have a thin, consistent film—not a thick coating—protecting the metal.
Lubricants That Can Actually Damage Your Tow Bar
There is a pervasive myth that standard axle grease or heavy white lithium grease is good for tow bars. In reality, these heavy greases are a mistake because they are exceptionally sticky. They act like flypaper for sand, dust, and gravel, which embeds into the grease and creates an abrasive grinding compound that destroys tow bar seals.
Avoid using standard, non-silicone penetrating oils (like the original WD-40) for regular maintenance. While these are excellent at loosening stuck bolts, they are designed to evaporate and do not provide the long-term friction reduction needed for sliding arms. Using them frequently can strip away any remaining protective film, leaving your metal vulnerable to immediate corrosion.
Never apply graphite-based lubricants to your tow bar. While graphite is a great dry lubricant for locks, it can react poorly with certain metal finishes and is unnecessary for the mechanical tolerances of a tow bar. Stick strictly to products labeled as dry silicones, PTFE-based lubes, or specialized tow bar formulas.
Your Tow Bar Maintenance Checklist & Schedule
Establish a routine based on your actual road time rather than just a calendar date. For a full-time traveler, a quick wipe-down and re-lubrication every 2,000 to 3,000 miles is ideal. If you are a weekend warrior, a maintenance check at the beginning and end of every season is a non-negotiable standard.
- Pre-Trip Check: Extend the arms and check for smooth operation. If you feel any “grit” or resistance, clean the shafts immediately.
- Monthly Wipe-Down: Use a clean rag to remove road grime from the exposed arms, even if you do not re-apply lubricant.
- Post-Season Deep Clean: Thoroughly degrease the unit, inspect for deep scratches or signs of rust, and apply a fresh coat of high-quality protective lubricant before storage.
- Storage Tip: If possible, store the tow bar in a covered or protected space to prevent moisture from settling in the joints.
Consistency is more important than the specific product you choose. Whether you are using a premium anti-corrosion spray or a standard silicone lube, it is the regular application that keeps the equipment safe. Stay diligent with these tasks, and your tow bar will remain a reliable partner for many years of nomadic travel.
Taking control of your tow bar’s health is a small investment in time that pays massive dividends in peace of mind. By establishing a clear cleaning and lubrication schedule, you ensure your equipment stays as agile as your lifestyle demands. Rely on these proven products and practices to keep your connections secure and your transitions effortless, no matter how many miles lie ahead.
