Not sure which 2005 Toyota 4Runner Suspension Systems are right for you? We have over 1691 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Joseph F from Great Falls, MT said, "Installed on 05 Toyota 4Runner. Took exactly 2 hours. Works exactly as advertised! Before, my 4Runner sagged really bad in the back with my camper attached. I only used 25lbs (out of 35 max). When I aired up, the back of the vehicle lifted about 2 inches. Absolutely no sag when towing and it feels like I have nothing behind me. This is a fantastic product! NOTE: On the 4Runner, it's not necessary to remove the coil/stabilizer bar. A little tight but can be done - I'm proof of that. If anyone needs any advice on install, please e-mail me at KYFHO69@Bresnan.net and I will be more than happy to help. I highly recommend this product!"
