Why Upgrade from Wet Bolts to Heavy-Duty Shackles?
Factory wet bolts are one of the most common failure points in RV trailer suspensions. These sealed units can't be lubricated, so they gradually seize from corrosion and wear, leading to harsh rides, squeaking noises, and eventually complete failure that requires expensive emergency repairs. When wet bolts seize, your suspension can't articulate properly, transferring brutal road shock directly into your RV's frame and causing interior damage, cracked walls, and broken components. The MORryde UO12-016 shackle kit eliminates these problems completely. The greasable design with Zerk fittings allows you to maintain proper lubrication with a simple grease gun, preventing corrosion and ensuring smooth operation for the life of your trailer. The heavy-duty construction handles the punishment of rough roads, potholes, and heavy loads without the premature wear that plagues wet bolts. Mobile RV technicians recommend this upgrade because it transforms ride quality, reduces maintenance headaches, and prevents the costly repairs associated with seized wet bolts.

Frequently Asked Questions
How do I know if I need the UO12-016 or a different shackle kit?
Measure your existing shackle width. The UO12-016 is designed for 2.25" width applications on tandem axle trailers. If you measure 3-1/8", you need the UO12-021. For triple axle trailers, choose the UO12-023. Count your axles and measure carefully before ordering.
Can I install this shackle kit myself?
While experienced DIYers with proper tools can complete the installation, professional installation is recommended for best results. This upgrade involves suspension components that affect safety and handling, so proper torque specifications and alignment are critical.
How often do I need to grease the shackles?
Grease the Zerk fittings every 3-6 months or before long trips. Regular lubrication prevents corrosion, ensures smooth operation, and extends component life. Use a standard grease gun with quality lithium-based grease.
Will this kit fit my travel trailer or fifth wheel?
The UO12-016 fits tandem axle RV trailers (travel trailers, fifth wheels, toy haulers) with 2.25" shackle width. Verify your axle count (2 axles = tandem) and measure your shackle width before ordering.
What's the difference between wet bolts and heavy-duty shackles?
Wet bolts are sealed units that can't be lubricated, leading to corrosion, seizing, and premature failure. Heavy-duty shackles feature greasable Zerk fittings that allow regular lubrication, preventing these problems and providing smoother operation, better ride quality, and longer life.
How much better is the ride quality after upgrading?
Most RVers report noticeably smoother handling, reduced road noise, and less harsh impact transfer after upgrading from seized or worn wet bolts to MORryde heavy-duty shackles. The improvement is especially dramatic if your wet bolts were seized or corroded.
