Constant-load and lift requirements
The 500-lb specification refers to constant weight, not a claim that the springs add 500 lb to the truck's rated payload or towing capacity. Select these springs for the manufacturer's stated load condition rather than assuming they are the appropriate choice for an otherwise unloaded truck.
Lift depends on the exact application and TRD Sport package specification. The 1–1.5-inch figures are not an adjustable lift range. Refer to the exact vehicle row in Bilstein's application table.
Bilstein recommends use with a heavy-load rear shock. Shock absorbers and front suspension components are not listed as included. These rear springs supply lift; this is not a complete four-corner suspension kit.
Spring specifications
Progressive rear springs with black finish. Bilstein lists a rear main spring rate of 251 lb/in.
