Multi leaf spring pack conversion tips for your boat trailer

Welcome back,
So you want to improve ride quality on your boat trailer...
I don't blame you, I did as well. In this video I won't be showing you how to replace them, there are plenty of those videos around. I will be giving you tips on how to obtain measurements for your boat trailer to select the right type of leaf springs for a 1/1 direct swap of some upgraded leaf springs. If you have a single leaf setup on your trailer, those can break and they can and can leave you on the side of the road when they do. Swapping to a multi leaf pack setup not only diminishes the chances of that happening to you, but it also creates a really nice progressive handling ride on your trailer to make towing your rig so much more easier on your mind.
By adding additional leafs, it also allows you to "lift" your trailer, which in essence allows you to run a larger rim and tire combination. A great upgrade to those with 13" wheel setups who want to upgrade to 14's!
This video targets #basstracker Classic XL owners who want to do the upgrade as the measurements I provide are specific to them, but it also applies to all of the other tin rig, aluminum boat owners out there because just about all boat trailers run leaf spring setups.
If you walk away with one thing from this video, just remember, eye to eye length x width x height. Very important!
Lets get you out there!

nice tutorial- It appears to me that the easiest way to accurately measure the eye-hole center to center should be this = measure from the outside ot leafspring{rolled portion) to the opposite side's inside edge of leafspring(rolled portion).

[@extremeboating7347]

Thanks Douglas! That's actually a pretty good suggestion for getting somewhat accurate measurements if the leaf/ leaf pack is still on the trailer. The problem is that most people will be measuring with it bolted into place so it will not be as easy to obtain precise measurements. Regardless, they will be able to obtain a relatively close measurement and from there they can select the appropriate leaf spring pack for their trailer's specs.

Do you have part numbers for what you purchased? I have a 2022 Pro170, and I’m wondering if the same parts will work since they are almost the same boat with the exception of the casting deck. I’m also wondering if you could let us know where you jacked up the trailer and approximately how long did the swap take? Thanks!

[@extremeboating7347]

Are you wanting a video on all that or a simple explanation over the comments? I'd be happy to help you out, but it sounds like there is a lot you want covered, and so I'm not sure in which way would be best to tackle what it is you are needing/ asking.

[@bwarholak]

@@extremeboating7347 I think I can figure out where to jack the trailer, so no worries on that. Do you think the same parts would work with a 170 trailer, and how long did it take for you to complete the swap? Thanks in advance.

[@extremeboating7347]

There is a beam right in front of the axle that I slipped my trucks bottle jack under to use to lift it. Yes the same parts would work without question. The swap overall will take about an hour or less for both sides if you know what you're doing and if you take your time. It's a very easy swap to do and I contemplated maki g a video showing folks how to do it, but figured there were already enough videos on YT showing how to do that so I skipped out on that part and just did it in peace.

Nice video, I just did the same thing for my Tracker Pro160 trailer. I drove it around the neighborhood and the difference was noticeable immediately. Like you my original u-bolts still worked out, had a little bit of an issue with the shackle bolts. One of the nuts stripped out and have to get some more. Luckily I had some lock nuts that fit, good for now but will replace with OEM hardware. Have you had any issues since upgrading to 3 leaf? Thank you!

[@extremeboating7347]

Zero issues with the tri-leaf setup since install. I always mod for reliability and not short term improvement. I'm glad that the setup is working out for you and just know for the future that you will have no issues as well. It's crazy how much of a difference it makes in over handling of the rig right?! Thanks for taking the time to check out the video and I'm glad to see I could help you out in modding your rig!

[@KelShep07]

@@extremeboating7347 Good to know! I do have a question about the tightness of shackles and the bolts, I've read that there should be a little play in them and to not over tighten so they cannot move. What are your thoughts on this? I'm reading mixed advice on the web. thanks again.

[@extremeboating7347]

The front bolt gets tightened the rear gets left with some looseness on it. So the shackle can move allow the leafs to move around. If you have any doubts, emulate the way it came exactly from the factory. They installed things on the trailers.

[@KelShep07]

@@extremeboating7347 okay understood. Before I took it all apart I made a note of that, one side had some play to it, the other was tightened up haha! Thank you

[@Tightlines123]

What size and style rims are those. I dig the gold big time.

[@extremeboating7347]

Well thank you! I got them because they match my truck pretty well. They are 14" Sendel T17's. Model: T17-45545MG

[@johnkrauss8982]

Does this add height to the trailer?

[@extremeboating7347]

Yes it does. It makes the overall height of the trailer and the boat on the trailer slightly taller than OE.

[@johnkrauss8982]

@@extremeboating7347 Thanks. My boat has about 2” to spare getting into the garage. May not be able to upgrade

[@TheFlynxman]

I’d like the name of the boat store you got them from. Thanks in advance.

[@extremeboating7347]

B&D trailer sales Martinez, CA They should be able to ship out a set to you if you want them no problem.

[@TheFlynxman]

@@extremeboating7347 did you just tell em you needed 3 leaf 1750 lbs 26 inch springs?

[@extremeboating7347]

@TheFlynxman yes sir. I told him I wanted to buy a triple leaf pack set. These are the specs I gave them and this assumes you own a Bass Tracker Classic XL. Other trailer spring sizes will vary. - 26.25" long springs - 1 3/4" wide - Double eye leaf - Triple spring pack - 9/16" standard holes - 1750 lbs per spring

[@philliplocklear4807]

Were did you get your leaf springs

[@extremeboating7347]

I sourced them from a local trailer supply store. I didn't really talk about it in the video because you can usually obtain them by providing the measurements and specs of yours and the type of springs (or the ones I supplied in the video if you have a Classic XL) to a trailer supply store local to you. If you'd like the name of the spot that I got them from, however, I'm sure they'd be more than willing to ship them out to you in a different state.
