Hi Fern,

The SumoSprings Solo Custom Helper Springs # SSR-612-40 could still be installed even though your Tacoma has a 2" rear lift. These sit between the leaf springs and frame so you'd likely not even see a difference with the lift unless that allowed some preload on the leaf springs. If you didn't have enough space between the spring stack and frame you could trim the Sumo's down to make them fit and if there's too much space they just won't engage until enough weight is added, which would honestly give you a more comfortable ride quality anyway.

Hey Fern, how did the SumoSprings work out with your Tacoma’s 2-inch rear lift? It’d be great to know if the fit and ride quality matched what you were hoping for. Your update could make it easier for others setting up a similar suspension.
