If you’re looking for not-too-tall and not-too-small, Rough Country’s 3.5” Lifted Knuckle kit is the perfect option for increased ground clearance and aggressive good looks! This all-inclusive kit features everything you need for a stunning, new appearance and enhanced off-road action, with a host of features designed to promote an incredible suspension geometry and ride quality!

 

Rough Country’s 3.5-inch kit features a set of lifted knuckles allowing you to lift your vehicle in the best possible way. Other kits only replace your upper control arms which can leave your CV boot prone to damage by making contact with the lower arms. Rough Country’s innovative, lifted knuckle design gives you plenty of clearance to keep your CV out of harm’s way while promoting a better upper arm ball joint angle and better ride quality to boot.

 

This kit includes Rough Country's premium N3 shocks! These 10-stage variable valving, high-pressure Nitrogen charged shocks offer a fantastic blend of off-road action and smooth highway ride quality. Also included in this kit are a set of fabricated rear blocks that are stronger and offer a longer lifespan than cast blocks while being less susceptible to damage and the environment.

 


Some vehicles may require additional modifications or parts.
