Squeaky, dry suspension joints make every mile feel rough. This step wet bolt has a built-in, threaded grease zerk that lets you easily add lubrication right where it’s needed. Regular greasing keeps the bolt and bushings moving freely, cutting noise and wear so your suspension works smoothly mile after mile.
A solid suspension starts with hardware that won’t loosen or shear. The 3-5/8" long bolt is made from strong steel with a 9/16" diameter shank and fine 7/16"-20 threads for a secure hold. Once tightened with the proper 7/16" flange nut (sold separately), it keeps your leaf springs firmly attached to hangers or an equalizer for a stable, predictable ride.
Corrosion can weaken suspension bolts fast, especially when exposed to water or road grime. The silver phosphate coating on this wet bolt resists rust and oxidation, helping it stay clean and functional over years of use. It’s a small detail that pays off in longevity and less maintenance down the line.
Getting the bolt seated right shouldn’t be a fight. The tapered design slides into place with less effort, seating securely in your hangers or shackles without damaging threads. Combined with the grease zerk for simple upkeep, this design makes both installation and long-term maintenance straightforward—even for DIYers who handle their own trailer care.

Good morning. I ended up going 8,500 miles, and all was well with theinstalled parts from etrailer.com. Shortly, I will re-inspect the parts in preparation for this years 6,000 mile summer RV trailer trip

We upgraded our camping trailer last fall so I’m no longer in a position to do a follow up review. Sorry, but the parts worked great while we owned it and gave piece of mind on the road. Thanks again for the parts and service you folks provide, you’re top notch in my opinion!
