This is the results of a homemade Toyota 6 leaf pack. I purchased a tsb set from AK27 a few months ago and wanted to insert one or two of those leafs into my tsb pack. I have the toytec 1.5 tsb aal in right now and will be removing it in hopes to gain more capacity for towing our trailer without sacrificing ride quality. The toytec aal worked fine but the arch of it never really matched the factory pack. I noticed the end of the leaf was bent up and was doing most of the work while the rest was pretty much flat. The only way I could match the arch perfectly was to use Toyota leafs so I thought I would give it a try.
I made two aal’s from the donor pack. A long one and shortone. In the first picture you can see the difference.
I would make the long one from the second leaf down from the top, that wraps itself around the bushing mount at the front, and the second shorter one from the leaf that is right above the thick overload leaf. I would cut the two of them so that they would sit just below their respective leafs in my pack on the truck. See pictures. I drilled holes at the ends for the factory friction pads to sit in. They weren’t round but I cut them to fit into round holes and set them in when the paint was wet so they would stick a bit better.
Install went not bad. The long one was very tight inserting it through the factory clamps that hold the pack straight. With some prying and words of encouragement they went in. The passenger side was worse cause of the exhaust system being in the way. The short one just went in where the toytec aal was.
I gained about ¾ inch of additional height with the new pack versus from the tsb aal. The tsb aal lost 2& ¾ inches with the 670 lbs over the hitch and the new set up loses 2 inches with the same weight over the hitch. I am a little over an inch higher with the same weight in the back. The first picture is the tsb aal with 670 lbs and the second is the new 6 pack with the same weight.
The arch of the leafs are all the same now. The ride is the same as before and feels great. I am looking forward to the first trip with the trailer and will report back how it fares on the highway and post some pictures of the difference with the trailer on.
I put camburg UCA's on at the same time so i will need another alignment before we go on holidays.
