Thank you for choosing Rough Country for your suspension needs.
Rough Country recommends a certified technician install this system. In addition to these instructions, professional knowledge of disassembly/reassembly procedures as well as post installation checks must be known. Attempts to install this system without this knowledge and expertise may jeopardize the integrity and/or operating safety of the vehicle.
Please read instructions before beginning installation. Check the kit hardware against the parts list on this page and the product layout on the last page. Be sure you have all needed parts and know where they go. Also please review tools needed list and make sure you have needed tools.
As a general rule, the taller a vehicle is, the easier it will roll. Seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur. Generally, braking performance and capability are decreased when larger/heavier tires and wheels are used. Take this into consideration while driving. Do not add, alter, or fabricate any factory or after-market parts to increase vehicle height over the intended height of the Rough Country product pur­chased. Mixing component brands is not recommended.
Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be re­sponsible for any product that is altered. products please call one of our customer service representatives at 800-222-7023.
This suspension system was developed using a Maximum tire size of 305/65-18 (33” diameter) tire with factory wheels. For aftermarket wheel and tire combinations consult your tire and wheel specialist.
This kit was designed to level the front of the truck with the rear. This kit includes a strut spacer and strut spacer shim plates to “fine tune” the front with the rear. Before installation is initiated, measure the front and rear of the vehicle to determine how much lift will be needed to level the vehicle. Each shim plate represents approx 3/8” of lift and will be installed on top of the strut spacer as shown in the instruction sheet. (Maximum 2 per side). The spacer alone without shim plates will achieve approx 2 1/4” of lift, can be used without strut spacer shims if desired.
In some cases, the vehicle owner may want the rear of the vehicle lifted also. Rough Country offers an optional 1 1/2” block and u-bolt kit is also available to raise the rear if desired. Part # 6559
