Note: Front springs have a minimum of 4.50 total coils, maximum free height of 8.75" and 5.75" outside diameter. Rear springs have a maximum free height of 13.0" and 5.25" outside diameter. 1500 lb. Δ to Solid: The measured deflection to solid height with a preload of 1500 lbf. and a 19 mm rise plate.
750 lb. Δ to Solid: The measured deflection to solid height with a preload of 750 lbf. Δ to Solid: The deflection to solid height as measured on a sample spring on a Instron SF1230. These values may vary due to manufacturing tolerances.
