I put in an order for Stage 3 for a 2016 GX460. I calculated +340lbs up front (accounting for skids, bumper, half the weight of sliders and roof rack), and in the rear I calculated 335lbs (gas tank skid, bumper, spare on bumper, half of roof rack, half of sliders and a 290 tongue weight for a trailer towed occasionally).
This is what I selected:
(Front Springs: 2.5" Lift Constant Load (110-220LBS Additional Payload), Rear Springs: 3" Lift Performance Plus (440-880LBS Additional Payload), Does Your Vehicle Have KDSS? Yes, Do You Need A Rear Airbag Delete Kit? Yes)
Where my selections correct?
