Bigger tires need clearance and adding that suspension lift is only half the battle. Spidertrax 1.25" thick, 5 on 150mm bolt circle, 6061T6 aluminum spacers are an easy way of spacing out front and rear 2007-Up Toyota Tundra, 2008-Up Toyota Land Cruiser, and 2008-Up Sequoia axles that run OE wheels. This added spacing is necessary for keeping those larger tires from crashing into your frame rails and suspension links at full turn. Simply bolt-on like a wheel, and off to the trails you go.
