A smooth suspension depends on the right hardware. This 3" long Dexter shackle bolt secures 1-3/4" wide double-eye springs so the suspension can flex properly without binding. It’s a solid replacement bolt that restores movement and helps the springs do their job mile after mile.
Road spray, salt, and grime can eat away at untreated hardware. The zinc-plated finish on this bolt keeps rust at bay, so you can use it in wet or coastal environments without worry. The protective coating helps preserve both the bolt and the suspension parts it connects.
This bolt’s 9/16" diameter and fine-thread design provide a secure grip that stays tight. The precise threads make it easy to snug the nut down for a solid connection, while still letting the spring pivot smoothly. That means fewer squeaks and clunks and a suspension that works the way it should.
When you’re keeping your E-Z Flex setup in shape, this bolt is made to fit right in. It works as a replacement for E-Z Flex suspension kits K71-652-00 through K71-660-00, giving you the correct size and strength for dependable operation without guesswork or modification.

Great customer service. Received in 3 d ays.
Perfect replacement for my 1971 Streamline Duchess.
Quality bolt, had to grind down the spines a little to drive into shackle mounts.
Shackle bolts fit perfectly.
Size is good and quality seems good also. For some reason the associated nut doesn’t seem to be available from this vendor
Its a bolt, machined correctly, not more to say than that. Should be sold with the lock nuts though, I had to buy them at Fastenal.
work well.

Bolts as expected, but why can't they come with a nut.
Completely restored our 1987 8x 10 trailer, turned out great. I found all the required parts from etrailer. Shipping was fast. etrailer was excellent to deal with. Thanks etrailer, best regards
I wish they would come with nuts, or tell us nuts are not included.
Exact replacement for the original Dexter parts for my 3500 lb single axle trailer suspension.
I explained what was needed,and all products was delivered as promised with great quality.
The parts arrived quickly. Great experience and great communication.
