3. This suspension system is designed to be used with wheels with a backspacing of 3-3/4” or less. Wheels with greater then 3-3/4” backspacing including some factory wheels will interfere with upper control arm and cause damage to OE parts and/or tires. Distance from hub mating surface of rim to the sidewall of tire can not exceed 4-1/2”.
4. Exhaust modification:
a. Cross over pipe alteration is necessary to accommodate this suspension system on 6 cylinder models.
b. Trail Master offers kit NX3O accessory to perform this modification.
