T100 Sliders...

Mr. Sixtyseven,

I noticed in the picture of your Tundra...

...that it appears you had to address the same issue with your sliders that I will with mine. That issue is the fact that the bottom of my frame rails are higher than the rocker panels of my body, meaning the sliders brackets will have to angle up to the frame (as your's appear). Is that the case?

Also, did you make yours bolt-on? That is my plan and I'm just curious how you went about bolting yours to the frame. Do you have up-close pictures of the bolting arrangement? Any info that may help me? I should be ordering steel next week. :ylsmoke:

(BTW, make some room in your PM inbox )

oops...i cleaned my room ...should work now .

the frame is slightly lower than the body. The sliders actually sit up a hair higher than the lowest point on the belly skid (needed room for tcase xmember, xhaust, xcetera), but about level with the bottom of the frame iirc.

the angle was to provide more weld surface and more structural support, the trimmed sections were placed in the lower corner of the interface between the plates and the standoffs to provide a larger contact patch on the frame, and create more of a compression load at the top of the plates & frame vs tension load on the bolts at the bottom of the plates. it's also why they're "glued" on as well as bolted--it distributes the load better.

if they just stuck straight in, they'd link at the bottom of the frame, where they'll be more exposed to hanging on rocks, and the bending load would require a large gusset on top that might well act as a can opener on the frame. it was better on my 1/8" frame to use 0.25" plates, seam sealer, and 3/16" square tube, angle cut, with gussets on the bottom, to spread the load more reasonably over the frame. the entire structure is biased slightly toward the bottom of the plates but only because of the gussets. There's enough surface area, and the plates are thick enough, that I don't worry about the frame.

Structurally it's equivalent to a straight section with an upper gusset, but this way put a ton of surface area where it was needed most, at the top of the connection, with the gussets in tension at the bottom. the quarter inch plates take care of the rest.

the plates have a 3/16" grade 8 bolt in each corner, and the largest plates have another pair in the center at top and bottom as well. I don't worry about them coming off.
