ROUGH COUNTRY 921375300A 5 Inch Radius Arm Kit

Product Information

• Product Name: RAM 2019 3500 Standard Duty DRW 5 Radius Arm Kit
• Product Code : 921375300A
• Manufacturer: Rough Country

Product Usage Instructions

1. Safety Precautions:

   • Due to the possibility of rollovers, it is strongly recommended
     to equip the vehicle with a functional roll-bar and cage system.

   • Always wear seat belts and shoulder harnesses.

   • Avoid situations that may lead to side rollovers.

   • Inspect and replace the steering stabilizer if necessary, especially when adding larger than stock tires.

   • Braking performance may be decreased when using significantly larger/heavier tires and wheels. Exercise caution while driving.

   • Do not add, alter, or fabricate any parts that increase vehicle height beyond the intended height of the Rough Country product purchased. Mixing component brands, lifts, and body lifts with suspension lifts voids all warranties.

2. Tire Installation:

   • This suspension system was developed for a 37×12.50 tire on an aftermarket wheel with a minimum of 5 backspacing.
   • When installing larger tires, speedometer recalibration is necessary.
   • Due to ride height inconsistencies from the factory, slight trimming of the front plastic valance may be required for proper tire clearance.

3. Carrier Bearing Shimming:

   • For vehicles equipped with a two-piece driveshaft and carrier bearing (such as the Mega Cab), there may be a potential take-off vibration.
   • This can be corrected by shimming down the carrier bearing using the included shims and hardware.

4. Warning Decal:

   • Any vehicle equipped with a Rough Country product must have the Warning to Driver decal installed on the sun visor or dash.
   • The decal serves as a constant reminder of the vehicle’s unique handling characteristics.
   • It is the responsibility of the installing dealer to install the warning decal and forward the installation instructions to the vehicle owner for review and to be kept in the vehicle for its service life.

Product Use Information

• As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend, because of the 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 it as necessary.
• Braking performance and capability are decreased when significantly large/heavier tires and wheels are used. Take this into consideration while driving.
• Do not add, alter, or fabricate any factory or after-market parts that increase vehicle height over the intended height of the Rough Country product purchased. Mixing component brands, lifts, and/or combining body lifts 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 a 37×12.50 tire on an aftermarket wheel with a minimum of 5” back spacing. When larger tires are installed, speedometer recalibration is necessary. Due to riding height inconsistencies from the fac-tory, you may need to slightly trim the front plastic valance for proper tire clearance.
• 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 by shimming down the carrier bearing with the included shims and hardware.

Notice to Dealer and Vehicle Owner

• Any vehicle equipped with any Rough country product must have the “Warning to Driver” decal installed on the sun visor or dash. The decal is to act as a constant reminder for whoever is operating the vehicle of its unique handling characteristics.
• INSTALLING DEALER—I t is your responsibility to install the warning decal and to forward these installation instructions to the vehicle owner for review and to be kept in the vehicle for its service life.

PARTS

FRONT SUSPENSION INSTALLATION

1. Secure and block the rear tires of the vehicle on a level concrete or asphalt surface
2. Raise the front of the vehicle and support the frame with jack stands. Remove the front wheels and tires and set aside. Position a hydraulic jack under the front axle and raise the jack until the front suspension begins to compress.
