Ask DocSk8 (Expert Indoor Skate Building Advice) This forum is different then the other SkateLog forums in that it is not a discussion forum, but rather a place you can ask skate building expert Fred "DocSk8" Benjamin about building and repairing indoor speed, derby, and jamskate quad roller skates.

Default Sure grip Cushions on Super X trucks

I got my suregrip super X cushions in purple. All 8 of them are tapered.

Tried putting them on, they just look aukward on there. Checked online pics. Seems some people put a straight walled busing on the base and the tapered on the truck side. With the small side of the taper pointing towards the floor. Seems like there is no way to keep the truck centered in relation to the stud.

I got plain old Super X trucks.

Do I need straight walled bushing with the tapered? Do I need additional cup washers?

Also, Do you advise a pivot cup upgrade for the super X, mine are less than a year old and in good shape.

Thats because the cone cushion is shorter than the barrel cushion. It is not designed to go between the truck and the plate.

That is the way they were designed. It is possible to use the cones on both sides but you need some sort of spacer to make up for the difference in height.

Ideally whether you have 2 cones or a barrel and cone, the large diameter goes toward the truck. Some of our members have flipped the cone over so the narrow part is in the truck (with a barrel on the other side) but I have found no obvious benefit from doing so.

That is the preferred method.

The "pointy" end of the cone is about the same diameter as the adjuster nut. I run some of my sk8s without the cone retainer.

I have never found a better pivot cup for the SG plates (In fact, I use them in Power Dynes as an upgrade) Just replace as necessary when worn.

How do you rate the original black rubber bushings far as stiffness goes.

I ended up buying the purple straight ones to go with the my purple cones.

That crash I had 3 week ago was due to me trying my cushions too loose. I am hoping a set of purple ones will be one step looser than my original black ones.

If the purple cone / straight combo is too loose, I may end up just using the straight walled cushions for both upper and lower cushion.

The design intent is to be about the same durometer but more rebound. I cannot say for sure. I toss all the black rubber bushings I run into. Seriously, nothing I sk8 has them and nothing leaves my shop with them.

That would be a good place to start.

That will depend on how you adjust the action. Typically I set the action so you can just turn the small retainers (if you have them) with your fingers. That is almost as loose as you want to run them. If you get to the point you want to go looser, you can back off until there is no tension on the action but do not go to the point it "rattles".


If the purple cone / straight combo is too loose, I may end up just using the straight walled cushions for both upper and lower cushion.
If the purples are too loose another barrel will be a bit stiffer.
