All-Pro Off-Road Extreme Suspension Lift Kits

All-Pro Off-Road Extreme suspension lift kits gather everything into one package that has all the "trick" parts for your factory solid axle toy. That means flexy off-road performance, positive control on the highway—and stable, predictable suspension in all driving conditions, on or off-road. This is far more than a simple bolt-on kit. It provides up to 4.5 to 7.5 in. of lift, depending on the springs used. The front axle is moved forward 1.5 in. as compared to stock; and with just minor fender trimming, it provides room for 35 in. x 12.50 tires mounted on 10 in. wide wheels. With some additional firewall work, it's possible to fit up to 38 in. tires. Due to the extra flex, All-Pro recommends switching to the wider rear axle from a 1986-95 Toyota Pickup or 4Runner. These axles have larger drum brakes and are 3 in. wider than the 1979-85 rear axles. This allows for more clearance between the tire and frame that can otherwise be a problem when running tires larger than 33 in. All-Pro offers 1.5 in. wheel spacers (not included) to use on the front axle to match these wider rear axles. Order the Extreme lift kit with the options preferred for your application.
