I've been searching around for some larger coil spring spacers lately, I really wanted to avoid using the mr. gaskets on the bottom. I think i may have found a pretty good alternative for anyone who is interested and only wants to use a single top spacer. The daystar KT09100BK, is designed for the early 90's 4runner but with a little modification it will fit our vans very nicely.

Here it is next to my old mr gasket 1285, its about twice the size.

The diameter of the grove is just a little too big to force on, but if you cut a section out it will snug down nicely into the grove. I took out just under a 1/4" and it worked out really good.

Here it is with a 235 75 15 tire on a samurai rim.
