Durable Components. When changing a vehicle's suspension, the key to preserving ride quality is keeping the geometry of all suspension components as close to their factory angles as possible. Rough Country's new 4.5-inch Suspension Lift features a set of ultra-durable radius arm drop brackets, precision fit to bolt right into the factory mounts for an easier install and a more factory-like angle. Utilizing this conversion kit you're removing the factory independent coil shock and coil set-up and replacing it with a massive 2.5in piston, nitrogen-charged, 8-stage adjustable Vertex Coilover. Rough Country's Vertex Coilovers feature a monotube design with an external reservoir for increased oil capacity and damping sensitivity. When it comes to investing in a high-end kit, you'll be pleased to find that Rough Country's 2.5in piston design is beefier and offers an impressive 56% greater fluid capacity than the average reservoir shock. Each kit is paired with a monotube shock that provides optimal damping control.
Installation. Requiring cutting and drilling to install, an estimated timeframe of 6-10 hours is recommended to complete this full installation. This full kit can be installed at home and can be completed efficiently and quickly!
Limited Lifetime Replacement Warranty. Rough Country's 6-inch Coilover Suspension Lift Kit is backed with a limited lifetime replacement warranty towards manufacturer defects. As such, the product is protected from structural and workmanship damage after the date of purchase. With our industry-leading warranty give yourself peace of mind when using Rough Country's Suspension products!
