Slappy trucks
« Reply #660 on: January 15, 2026, 04:34:15 AM »
So just bought some Slappy ultra low king pins. Realized the stock bushings were way too soft and bought their 100a bushings. All was good until I popped a quick big spin and landed a little towards the toe side and the top bushing blew out.  Wondering if anyone has had the same issue? Contacted Slappy to see if there was an issue or if they may different sized bushings for these new trucks but no response. Any help is appreciated. I did throw a washer under the head of the kingpin to continue to skate them but would be nice to not have to do that after paying the money for these trucks. Seems the kingpin head is too small so when you tighten it down the top of the bushing gets pushed out.

Following this question, I ride pretty tight, 100 boardside / 95 roadside so the information may be helpful to me as well

They’re Awesome trucks don’t get me wrong. Will do whatever I can to make these things work. Bought some bones hard bushings to see if they work. You’ll see when you get them that the head of the kingpin is beveled eliminating the need for the washer that usually would go there but it’s just a tad too small for the bushings. Waiting on Slappy to respond see if maybe they will be coming out with different bushings to accommodate it or if they need to do a design change. Was watching a few videos on YouTube a lot of the guys that reviewed them like their trucks loose but one guy said he had the same issue where it blew out on him. I’ll post another comment on here if I get an answer back or if I find a different way to make this work. The trucks are top notch first set of trucks where while breaking them in they don’t squeak and quickest to break in. Like I said I threw that washer under the kingpin head and it’s fine but would rather not have to do that.

I normally ride Indys with 92a Blues, so I also ride a bit toward the "harder" side. I also ordered some of the Slappy 95a and 100a bushing to try putting in the bottom if stock was too loose for me.

On my non Slappy trucks I am running an ACE Hard/Med combo
Slappy gets the 100/95 combo - have not tested it yet, just set it up last night
And I feel you on the washer thing, I am about to run back through this thread because I think somewhere there is some talk about this issue.

Seems like a washer hack is just that a hack, the ULKP was purpose designed to remove the washer....
I really like the trucks so far, not enough to buy another pair yet, but I have just started riding them and will hold off on making a snap judgment

I had a similar problem with the slappy ultra low kingpin, I used the 95 bushings and they keep sticking to one side or the top bushing pops out. I don’t had a lot of tolerance for truck issues so went back to venture.

100% with you on that. I am a long-term Indy rider*, and when I’ve tried other trucks, if they start requiring a lot of my attention for whatever reason, it’s over.

*Had a set of standard Slappy trucks awhile back, and they were great. Very close to Indy (my gold standard). But, I do a ton ot feeble/smith grinds, so just kind of had to try these ultra low Slappys, for the obvious reasons. Will report back.

The V8 might be my next try - Now back to Slappy talk!

In the interview he did a few weeks ago
https://youtu.be/-TGPeD6jF5I?si=AotVrxgjQTFHdL_P

at 24:06 he shows an 8-hole baseplate, I am kinda stoked on that
Seems like a lot of stuff is out of stock all over, hoping in the next qtr the restock has some of the newer stuff he was talking about

Are the ultra low kingpin bushings the same size as the normal ones? I would have assumed they're shorter (top at least).

I have been using the slappy lows and liking them a lot. I need to try that 100/95 combo, 100 is a bit too hard...

Top is like 1/2 size of regular one. Bottom is the same.

And to the best of my knowledge Slappy does not have bushings for the ULKP

Thanks for bringing that to my attention, re 8 hole baseplates.

Been thinking of trying a DIY 8 hole on my set of Slappy trucks, just to see how they go, but didn't get around to it yet.

I had been drilling out my own for a while now on other brands and even got someone I know to fill them in so I could custom drill the holes exactly where I wanted them on my Indy standards, but more brands bringing out options like this should make things easier for anyone who doesn't want to go to the trouble I have, or mess up their baseplates, also as I have.

I would still like to get my hands on some more undrilled baseplates though, as that would be a lot of fun to drill them out exactly where I want them, usually a little closer to "right in the middle" but not quite.  The V8 or other 8 hole baseplate options are at either end, not so much in the middle, which is where I want things.


* Also I know Grind king has the open three hole options, but I am not about to get them.

Gone since 1988.  I talk too much about skateboards.  Sorry.

Are the Ultra Lows a pretty dramatic upgrade? I’ve got some pretty fresh Inverted plates but still considering buying a set of the new ones. They look a lot cleaner but performance wise I’m not sure I can justify it at the moment.

Can anyone tell me if they loosen on their own like the regular ones? They might bite the bushing a bit better.

I have not had any issues with my ULKP I am using them in non Slappy trucks.

So just bought some Slappy ultra low king pins. Realized the stock bushings were way too soft and bought their 100a bushings. All was good until I popped a quick big spin and landed a little towards the toe side and the top bushing blew out.  Wondering if anyone has had the same issue? Contacted Slappy to see if there was an issue or if they may different sized bushings for these new trucks but no response. Any help is appreciated. I did throw a washer under the head of the kingpin to continue to skate them but would be nice to not have to do that after paying the money for these trucks. Seems the kingpin head is too small so when you tighten it down the top of the bushing gets pushed out.

Following this question, I ride pretty tight, 100 boardside / 95 roadside so the information may be helpful to me as well

So I just got the bones hard bushings in that I ordered after I blew out the Slappy ones and they fit perfect and they’re great so far.

Sorry to derail the bushing talk, but I’ve been enjoying riding the low profile 50mm for 2 weeks and was wondering if those with prebook catalogs know if there is new stock coming out with different colors or solid hangers any time. It seems like the only low profile trucks have black plates and hollow, which is sold out on ther site Also Sinclair was on a YouTube with Andrew cannon and he had lots of trucks with him but no lows and seemed like he didn’t want to talk much about them. I hope they weren’t one run and done.Thx in advance.

I hope it's a staple in their lineup. I got them when they came, but only tried them briefly. Now I've been using them quite some time and I think I want to use them in the future too, really liking them!

I got a set of the ultra low Slappy inverted kingpins, which I have tried on most inverted baseplates of various brand trucks I have here, which all seem to sit well enough.

With regard to the question if they loosen - that would be down to the baseplate and the kingpin nut, more so than the kingpin itself.  No nyloc to hold it in = it is going to loosen off.  Nyloc that is not worn out or loctite or something similar = hold in place.

That is my understanding from all the inverted options I have.  More constant messing with the inverted kingpin, or swapping out bushings every other day and that nyloc is going to go pretty quickly.  Baseplates I have barely touched since setting up are still going fine and haven't moved at all, medium bushings, checked and marked kingpin head, etc.


Of course that is just one take, so that is not to say some might hold better, some worse or whatever, but if your existing kingpins are moving, I don't think trying different ones is going to help a whole lot.

At least here in AU that ultra low kingpin set is pretty cheap compared to getting new trucks, (even more if you get wholesale / shop discount) so that's why I got a set just to see what it was like, more than getting a set of trucks.

Gone since 1988.  I talk too much about skateboards.  Sorry.

Thinking of grabbing some of the ultra low kingpin baseplates and frankensteining on my stage 4 or Ace classic hangers. Apologies if I missed it, but is there a consensus height on the top bushing that should be used? Sounds like it's smaller than stock indy/thunder/ace. Bottom bushing just a 1:1 for most barrel bushings correct?

A few things on this...

First, I know Ace/Stage 4 has non-standard size bushings. I can't remember if that is in top, bottom, or both bushings. I am sure @Mbrimson88 knows. So, there might be some geometry issues swapping out Ace/Stage 4 bushings (IF you were thinking or doing that).

As to stock Slappy bushings, yes, the bottom bushings are all the same size across all their trucks. The top bushing on the ultra low king pin IS smaller/shorter, but I was actually shocked at little the difference is between it (e.g. ultra low top bushing) and the regular stock top bushings. However, unfortunately, I don't have an answer for you on what best options are other than the stock ultra low shorter top bushing would be.

Apologies if I missed it, but is there a consensus height on the top bushing that should be used? Sounds like it's smaller than stock indy/thunder/ace. Bottom bushing just a 1:1 for most barrel bushings correct?

A few things on this...

First, I know Ace/Stage 4 has non-standard size bushings. I can't remember if that is in top, bottom, or both bushings. I am sure @Mbrimson88 knows. So, there might be some geometry issues swapping out Ace/Stage 4 bushings (IF you were thinking or doing that).

As to stock Slappy bushings, yes, the bottom bushings are all the same size across all their trucks. The top bushing on the ultra low king pin IS smaller/shorter, but I was actually shocked at little the difference is between it (e.g. ultra low top bushing) and the regular stock top bushings. However, unfortunately, I don't have an answer for you on what best options are other than the stock ultra low shorter top bushing would be.


I just updated the Bushings thread with a better (current) list, so hopefully that should come up sooner now in searches.

Link here anyway:

* Machining top bushings down to about 8 mm is the same as what the "low bushing kits" had on them, which I often use on my trucks and then angle grind the kingpins down.  I made sure not so much to just cut any stock ones down, but also cone the tops so any and every washer fits on them well too.  Exactly how you go about that is up to you, but sitting them on a kingpin with other bushings under them to bring them up to almost the kingpin height and then running an angle grinder on the side worked really well just recently to lower the tops of two bushings.

Gone since 1988.  I talk too much about skateboards.  Sorry.

So just bought some Slappy ultra low king pins. Realized the stock bushings were way too soft and bought their 100a bushings. All was good until I popped a quick big spin and landed a little towards the toe side and the top bushing blew out.  Wondering if anyone has had the same issue? Contacted Slappy to see if there was an issue or if they may different sized bushings for these new trucks but no response. Any help is appreciated. I did throw a washer under the head of the kingpin to continue to skate them but would be nice to not have to do that after paying the money for these trucks. Seems the kingpin head is too small so when you tighten it down the top of the bushing gets pushed out.

Following this question, I ride pretty tight, 100 boardside / 95 roadside so the information may be helpful to me as well

So I just got the bones hard bushings in that I ordered after I blew out the Slappy ones and they fit perfect and they’re great so far.

On the ultra lows?

Yeah in the ultra lows. May raise the kingpin up slightly but not by much. Everything is good so far though.

The ULKP has extended threads so raising up a bit with a taller bushing should not be an issue
