Hi. Im currently on a 4/6 drop on my 99-02 single cab silverado. Rear runs fine but I'm the front would you recommend a bump steer kit? I'm on 2" spindles and your 99-06 viking coilovers you guy carry.
Usually a 4” drop wont require a bumpsteer kit, look at the tie rod angles with the truck on the ground. You can also call the shop or email us for any other questions
