Rough Country recommends a certified technician installs this system. In addition to these instructions, professional
knowledge of disassemble/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 ve-
hicle. Average professional install time for this kit is 4-6 hours.
Please read all the instructions before beginning the installation. Check the kit hardware against the kit contents list on
the last page. Be sure you have all the needed parts and understand where they go.
Product Use Information
As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend, because of rollover possibility,
that the vehicle be equipped with a functional roll-bar and cage system. Seat belts and should harnesses should be
worn at all times. Avoid situations where a side rollover may occur.
Also check the steering stabilizer. It is a good idea when adding larger than stock tires to go with a larger bore steering
stabilizer or a dual unit for tires 35
” and above. Inspect the stabilizer and replace as necessary.
Braking performance and capability are decreased when significantly large/heavier tires and wheels are used. Take
this into consideration while driving.
Do no add, alter, or fabricate any factory or after-market parts which increase vehicle height over the intended height
of the Rough Country product purchased. Mixing component brands, lifts, and/or combining body lift with suspension
lifts voids all warranties. 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.
This suspension system was developed for 37x12.50 tire on the stock 17
” x 9” or 20” wheels at 5” of lift. On an after-
market wheel you will need to purchase a 8 ” wide wheel with minimum of 4-5/8” of backspacing. When larger tires are
installed, speedometer recalibration is necessary. Due to ride height inconsistencies from the factory you may need to
slightly trim the front plastic valance for proper tire clearance.
This kit can also be used a 3500 single rear wheel truck. Use of this kit on a dual rear wheel pickup is not recom-
mended. Block and u-bolt combinations may vary with 3500 models.
On vehicles equipped with a two piece driveshaft & carrier bearing as on the Mega Cab, there is the potential
for take off vibration, depending on the severity this can be corrected with shimming down the carrier bearing.
Carrier bearing drop kit Part # 1110 is available from Rough Country. Also 2500/3500 trucks with factory over-
load springs the overload will have to be removed for the new block and u-bolt installation.
