Increase ride comfort and suspension travel. Pics show shackles for the rear but we recommend adding a leaf or using blocks/spacers. With this simple strut replacement you will get the advantage of adjustable coil plus approx. 6.5 inches of travel in the front so keep your tires on the ground over the rough stuff. These struts are custom built by Samurai Trucks specifically for the kei truck. This kit also increases height of truck by just over 2 inches. They are adjustable also to give up to 4.5 inches of lift but spacing of the transmission, engine, front diff etc. is neccesary. Kits can be ordered with different spring rates on order. You won't believe the difference this makes in your ride!
