-Dobinsons 210v are probably the most expensive rear coil, with a retail price of $230 +$40 in shipping (with tax you're pushing $290).

-Land cruiser coils can be found for $111 per side (McGeorge Toyota), often with free shipping if you get a promo code, total you're ~$237

-OME861 will be your least expensive (new) option. you can usually find them on Amazon for $187, shipped to your door in two days.

The reason there is a lot of interest in the Dobinsons 210v is that it is a stock height, stock weight, progressive rate coil. The specs are DS -285mm / PS -275mm free height, with a 182-217# progressive rate. This means that this coil is going to have a ~1/2in lower free height than the OME 861, while also providing a softer initial coil rate with the truck is unloaded. When the truck does have a bit of load (rear bumper, swing out, camping gear, and spares) the coil will compress the 182# section and get into the 217# section. So the hope would be that you'd end up with a 4-4.5in lift unloaded and then settle out to 3-3.5in of lift fully loaded. Not to mention it 'should' ride better unloaded than the OME861s, while retaining the weight carrying capacity of the OME861 when fully loaded.

This is all speculation though.
