Established in 1975, Superlift remains a pioneer in the industry, and is one of the few suspension companies operated by true truck and off-road enthusiasts. We are passionate about trucks, wheeling and an outdoor lifestyle that go hand-in-hand. We can talk the talk because we walk the walk.This question.... ''What's best for the customer?''... is always at the top of our list in everything we do, from product planning and design to customer service. This simple guiding principal has served us well for decades, and will continue to guide us into the future.We are proud to provide the truck, Jeep and SUV owner products that perform better than advertised. We understand that most people spend the majority of their windshield time on-road, and our designs reflect this. You will be 100% satisfied with our products on-road or off - we guarantee it! Determining what product is right for your vehicle and lifestyle can be a complicated task, especially with so many companies and options to choose from. We urge you to carefully research your purchase. Most lift kits represent a considerable investment, and you will literally live with your choice for years. Talk to fellow off-roaders, and your local automotive specialty shop before making a purchase. We love to talk shop, and we encourage you to give our tech staff a call. Bottom line... if you do your homework, you'll discover that we've done ours.
