4L SLIPPER SPRING ONLY S4ES45

4LF Eye to Slipper Spring 45mm x 8mm x 710mm (Rated 1100Kg a Pair)
These Slipper Springs are a very simple and durable option for boat trailer or to use a setup that offers good town and highway
driving. We offer these springs in Dacromet Coat for weather/sea proof and black painted springs as a standard product. They
also come in two different leaf thickness 6mm and 8mm the same principle applies to both, however the 8mm takes a higher load
rating. The standard ½” eye on the front of the spring is attached using the Hanger which is welded to the chassis rails and uses
½” 3.5” High Tensile Bolt to secure the spring to the Hanger.

‘Slipper’ refers to the end of the spring that rests upon the rear hanger that is welded to the chassis and absorbs the impact going
through the trailer. All though not recommended by us many trailers come with tandem or even slipper spring setups, it is quite a
low cost alternative for the reason that it doesn’t share the load evenly across trailer. It is a common problem for one side of the
trailer to lift shifting all the weight to one side causing it to damage the springs. So for that reason on tandem trailers:

at least 120% of the load on that axle with the trailer at its ATM; and
at least equal to the load on that axle with the trailer at its ATM and any retractable axle retracted.
. Therefore if you’re planning on driving off-road or on rough roads we recommended you move to a Shackle Springs or a Rocker
Roller Springs.
