  • Style
  • Ball Weight
  • Shank

STYLE - Standard or Classic

Hayman Reese Standard VS Classic WDH Bars Hayman Reese Standard VS Classic WDH Bars
  • Classic
    • T-bar / trunnion style
    • Bars come straight out horizontally from the cast head
    • Higher clearance under between ground and underside of head
    • Less clearance between A-frame and bars
    • Suitable for A-frame chassis heights up to 5.5"
  • Standard
    • Hook / Sheppards crook style
    • Bars drop down vertically under the cast head
    • Increased clearance between A-frame and bars
    • Use for 6"+ height A-frame

How to choose: measure the vertical height of your A-frame chassis. If it is 6" or more, go for the Standard unit.

Note: this rule is based on having the coupling plate (plate under the coupling) positioned on TOP of the A-frame (as in pictures above). Some vans, especially off-road vans, have the coupling plate positioned on the BOTTOM of the A-frame.

BALL WEIGHT CAPACITY

  • 600 lbs
    • Suit vans with ball weights between 135 - 275 kg.
    • Approximate loaded van weights of between 1.3 - 2.7t
  • 800 lbs
    • Suit vans with ball weights between 275 - 365 kg.
    • Approximate loaded van weights of between 2.7 - 3.6t

How to choose: weigh your van on a weighbridge to determine overall weight, and also ball load / down weight.

SHANK

Hayman Reese Shank Height Comparison Hayman Reese Shank Height Comparison

The "shank" is the L-shape or T-shape piece that goes into your vehicle's tow bar receiver. They provide the ability to raise or lower the cast trunnion head (the piece the bars go into). You need to get the correct length shank to suit your vehicle/van combination. This depends on the combination of the vehicle ride height, and the van's coupling height off the ground. The shanks can be used either way - up or down.

  • Standard kits include the "Standard" shank (L shape fitting which goes into the vehicle's tow bar receiver). T-shape. Gives you +25 / -184mm.
  • "No Shank" kits don't include the shank. Better value if you need a longer shank to suit raised vehicle or higher vans.
  • 30mm drop shank (L shape)
  • 95mm drop shank (L shape)
  • 160mm drop shank (L shape)
  • Shanks can be used up or down.

The adjustment is a measure of the vertical offset between the centre of the hitch receiver and the base of the tow ball.

How to choose:

With all gear set up correctly, van should be travelling level, and vehicle should be sitting down approx 15-20mm evenly both front and rear.

 

  1. Position vehicle and van on very level surface (e.g. shopping centre car park). Have them "almost" touching - ie ready to couple.
  2. Ensure caravan is level front to back - adjust with jockey wheel and measure from ground to under chassis front and back to ensure dead level.
  3. Measure height from ground to underside of coupling on the van (Dimension A)
  4. Measure height from ground to centre of the vehicle receiver (Dimension B).
  5. Calculate difference A-B.
  6. Select shank height based on this difference.
    1. e.g. if difference is -20mm and you are using the "Standard" WDH kit, the "Standard" drop shank included in kit is fine.
    2. e.g. if difference is +170mm and you are using the "Classic" WDH kit, you will need the 30mm drop shank (and turn it upside down).  If you are buying a new kit, it is better value to purchase the "No Shank" WDH kit, and then purchase the 30mm drop shank separately.
