Questions and Answers

Will it need realigned? Will it ride rougher?
View Staff Answer 

Ride characteristics often change after instillation of suspension parts. After the completion of the installation, Tuff Country EZ-Ride Suspension recommends taking the vehicle to an alignment shop and having a proper front end alignment performed. Tuff Country EZ-Ride Suspension also recommends having the alignment checked every 6 months to ensure proper tracking, proper wear on tires and front end components.

Do I have to replace the stock shocks with this kit??
View Staff Answer 
You don't have to. Tuff Country states that new shocks are optional and not required on the 12034 2" lift kit.
