Will do ... It is designed as bolt-on. For a HF frame, bolting it on is your best bet. For other frames like welded square tubing you can weld the hangers directly to the frame.

I really like the idea of welding all the new spring mounts to a piece of angle iron and then bolting that to the frame.

If anyone is interested I can weld and kit up these bolt-on, soft riding spring setups.
Simply unbolt your existing HF spring hangers, clamp the new ones in place, drill a few hole, bolt them on and no more shaking your trailer to death.

Kit includes:
• Pair of bolt-on replacement springs hangers
• Pair of 4-leaf premium trailer springs
• Shackles and spring bolt kit

Kit price will be $139.
Can also sell individual parts if someone wanted to weld there own hanger brackets. Will get them official list on our website in a week or two.
Also have replacement spring seats available. This save on cutting the old ones off and grind the spring center pins down because they are a tad long for the HF spring seats.
Maximum load capacity is 1150 lbs, can be tuned by removing springs for lower capacities.

I am looking for springs to put on my 40x48 HF trailer. Does anyone see a problem with removing two leaves from a four leaf 1750lb spring and using them on this little trailer? The spring in question would be something like this: http://www.etrailer.com/Trailer-Suspensi.../PR4B.html

I am asking because I can get springs like these cheaply and conveniently. My other option would be the 28" 540 lb springs from stengel bros, but if I can remove two leaves from the 1750 lb springs and get roughly the same result, it would be much easier and cheaper for me. Any thoughts?

EDIT: Sorry if this is the wrong section, I just realized this thread is in "Tech Tips". My bad on that.

What is the planned loaded weight of your trailer?

I can't imagine it would be more than 1000-1200 lbs at the most, and probably much less than that most of the time. I am just planning to do a plywood box with a rack on top for kayaks/bikes and possibly a RTT one day. It would be for hauling camping gear/cooler/water/spare tire (31" truck tire). I have a bigger utility trailer for hauling heavy stuff.

After thinking about it more, I am leaning toward just spending the extra money and getting the springs with a known weight rating.

Going with the lighter rated springs is a better bet. If a smoother riding spring is important, our 4-leaf, 29" is the smoothest riding trailer spring you will find, although they cost more. If interested check out the Trailer Frame Parts in my online store.

Wait, will your bolt on kits fit the small HF trailers also? For some dumb reason, I was thinking that they were only for the 4'x8' models. And it also was not registering with me that your kit also includes the springs. In that case, I think I will be ordering from you Smile

Thanks for your help.

Yes will bolt right on the straight tongue 40x48 for kits. Only caveat is the axle needs to be under the springs to clear the tongue, this will "lift" the trailer a few inches. Thanks! ...

Ok so I read this post and for the time being will build my 1750# as is with the slipper springs but am looking down the road to modify to the double eye leafs but all I have read here so far involves swapping a lighter capacity set of springs in and that kind of defeats the reason I bought the heavier capacity trailer.

I have cut the length of the frame down to your EB plans and wonder when I do swap springs could I not just take the OEM spring hanger, cut it and re-bolt it to fit the new leafs with the shackles as long as the nub on the middle of the leif pack was centred where it was placed according to your EB plans?
