Made in the USA for a Reason - Since 1988 Tuff Country EZ-Ride Suspension has been and still remains one of the very few suspension lift kit brands that manufactures, designs and packages its products in the USA. Why does this matter? Buy a lift kit from nearly any other brand that imports their products from overseas and you will get inferior steel, components and hardware.

Many brands will also leave out important components that are crucial to proper suspension geometry. All can lead to fitment, alignment and sagging issues down the road. While Tuff Country may not be the cheapest lift kit on the market, quality components and happy customers are a higher priority.
