Say Goodbye to Squeaky Springs — Upgrade Your Trailer with Confidence! Tired of the creaks and groans every time you hit the road? Our Greaseable Shackle Bolt Kit is the perfect DIY fix to smooth out your trailer’s suspension and eliminate that annoying spring chatter.
At the heart of this kit are four 9/16" x 3" “wet bolts”—greaseable shackle bolts that make it easy to add lube right where it matters: between the high-friction contact points on double-eye springs. No more dry metal-on-sleeve groaning—just smooth, quiet travel.
The shackle plates are laser-cut from 3/16" steel, featuring a 3-1/4" bolt center for a precise fit. We tumble each one smooth to enhance powder coat adhesion, then finish them in a sleek, durable black powder coat that stands up to the elements.
Every kit comes complete with: ✔️ 4 greaseable shackle bolts (9/16" x 3") ✔️ 2 standard bolts (9/16" x 3") ✔️ 6 zinc-plated locking nuts ✔️ 4 heavy-duty powder-coated shackle plates
Built strong. Designed for easy maintenance. Perfect for DIYers who demand performance. Make your trailer smoother, quieter, and longer-lasting—one bolt at a time.
