PRO RAC GUIDELINES

 

    
  2. 

 

Please review the instructions and warranty carefully. Assembly and installation are the purchaser’s responsibility and beyond ProRac’s control. 
Therefore, ProRac exclusively limits its warranty to the repair or replacement of a defective ProRac product for up to three years from retail 
purchase. Warranty excludes damage to your vehicle, cargo, or any person or property during assembly, installation, and use. 
 

 

Do not carry more than 150 pounds (68KG) of combined cargo and accessories on ProRac load bars. ProRac load bars do not increase 
gutter or roof strength. ProRac cannot warranty loads that exceed this limit. 

 

Do not use ProRac load bars and accessories for purposes other than those for which they were designed. Do not exceed their carrying 
capacity. Failure to follow these guidelines or the product instructions will void the warranty. 

 

This step is performed on a workbench or floor, not on a vehicle.  

 

Make sure all knobs, bolts, screws, straps, and locks are firmly attached, tightened, and locked before every trip. All fasteners must be 
periodically inspected for signs of wear, corrosion, and fatigue. Check your load at stops during long trips to ensure continued fastening 
security. 

 
Lay the tracks side by side with the raised rib sides of the 
anchors facing each other.  

 

Check all local and state laws governing projection of objects beyond the width and length of vehicle. Be aware of the width and height of your 
cargo since low-clearance branches, bridges, and parking garages can affect the load. Never drive with any lock, knob, or rack in an open or 
unlocked position. All long loads such as, but not limited to, sailboards, surfboards, kayaks, canoes, and lumber must be tied down front and 
rear to the bumpers or tow hooks of the vehicle. 

 
Place the molded feet over the anchors. Place the load bars on 
top of the feet and select one of three mounting positions which 
corresponds best with your application.  

 

Remove your rack and accessories when they are not in use and before entering automatic car washes. 

 

 

All locks must be turned and moved periodically to ensure smooth operation. Use graphite or similar dry lubricant. Locks are designed to deter 
vandalism and theft. Remove valuable gear if your vehicle is unattended. Replacement keys are available only through your ProRac dealer. 

Position the load bar and selected mounting hole over the foot 
and screw the 1/4-20 X 2-1/4” button head screw through the 
foot and into the sliding anchor.  

 

All cargo will affect the vehicle’s driving behavior. For your safety, adapt your speed to the conditions of the road and load being carried. Obey 
all posted speed limits and traffic cautions. 

 

 

 

Due to their wind resistance, do not carry disks or wheels with covers on the ProRac bike carrier. 
Consult your ProRac dealer if you have questions regarding the operation and limits of ProRac pr

The load bars are used only for positioning the track and will be 
removed later.

 

Slide the three sliding tie downs and two crossbar sliding rack anchors 
onto the track, alternating tie downs and rack anchors.
