1.
Examine tow vehicle to determine adequate mounting surface to assure that attachments meet requirements of these
instructions and warnings. Make sure that no fuel lines, electrical wires, brake lines etc will be smashed, crimped, or
damaged in any way by the installation of this hitch product. No cutting, relocation or removal of tow vehicle components
can be performed without the approval of tow vehicle manufacturer(s) if required for installation of this product.
2.
Weld-On Option After determining location of frame brackets relative to center hitch section surfaces must be prepared for
welding. Paint and other surface treatments must be removed to allow adequate weld penetration and strength. Be careful to
grind paint off of hitch components. Also remove paint and or plating, undercoating, rust, oil etc from vehicle frame. Use a
flexible disc grinding wheel to remove paint etc. Using a rigid disc could cause gouging and notching of metal which could cause
high stress points and weaken hitch and or frame. All welds must be performed by a A.W.S. certified welder for the type and
position of welds being done.
Bolt-On Option Determine location of frame brackets to assure that at minimum (4) 5/8" diameter bolts per side can be
3.
installed, and that you have proper clearance for hitch and hitch accessories. Before drilling holes in vehicle frame remove any
rust or undercoating to assure that holes can be drilled accurately. It may be easier to clamp frame brackets in place and use
the holes in the brackets as guides to drill the frame. Make sure that there are no electrical wires, brake lines, fuel lines and
other obstructions inside of frame before drilling. Follow instructions in Diagram 2. below regarding maximum hole sizes,
minimum bolt sizes and strengths and the use of proper locking type nuts. Make sure to tighten bolts to proper torque
using a torque wrench.
This Diagram below shows required minimum requirements
for a bolt-on installation. It is the responsibility of the hitch
installer to determine the acceptability of the tow vehicle
structure for the hitch tow rating.
NOTES:
1.
Note all precautions in steps above.
Do not drill holes in frame more than 1/32" larger than bolt.
2.
Use 5/8" diameter bolts minimum, Grade 5 or stronger only.
3.
4.
Use locking type nuts with all bolts.
Must use at least (4) 5/8" diameter minimum bolts per side.
