Al-ko Caravan Shock Absorber Kit for Caravans with electric brakes
The Al-ko Caravan shock absorber kit is the favourite premium kit used on Jayco, Coromal and most modern caravans in Australia.
For a long time drivers have been worried about trailer vibrations on uneven roads. Until now, conventional standard shock absorbers have barely delivered a noticeable improvement in driving safety. They are designed for a weight range that is too large (for example 0 to 4.0 t). Optimum damping was only achieved at medium trailer weights (2.0 t). Damping in the lower weight range is excessive, causing trailer bumps and jolts, while the damping in the upper weight range is inadequate. AL-KO Octagon axle shock absorbers, on the other hand, improve the trailer’s drive characteristics and provide optimum damping – thanks to precise, weight-based, tuning.
- Damping road shocks.
- Direct reduction of dangerous jolts.
- Greater driving stability.
- Greater braking stability.
- Optimum ground contact.
- Install at an angle approximately 15% off the vertical, top to the rear of the trailer.
- Closed = 255mm Open = 380mm.
- Bolt size is 12mm
- Compression 80% Opening to 20% Closing.
- Shock absorbers are oil filled.
- 1600kg per pair.
- The normal operating position for these shock absorbers is 300mm.
- Bottom brackets can be flipped to gain or reduce the distance.
- Brackets not included. Click the image to buy shock absorber brackets.
Alko shock absorbers greatly assist braking by substantially removing the effects of vibration fatigue.
Vibration fatigue occurs in caravans and RV’s on rough roads, The vibration causes magnet rattle on the magnet arm which in turn damages the electric magnet.
For the best results, shock absorbers should be installed 90 degree’s to you spring travel. In most, this is 15 degree to vertical.
Install on an angle of 15 degrees to the vertical and about 300mm length or 1/2 open.
We cyclic test every batch of trailer shock absorbers to destruction to support the best quality of your equipment.
Worn parts, parts rubbing together, loose nuts, worn utensils, etc. are all signs of a trailer without a caravan shock absorber.
Why are caravan shocky’s important for caravans?
Do you remember Henry Ford? Ah yes, I thought that name would ring a bell.
Old Henry never put shocky’s on cars until he got sick of the rough ride. He also needed to sell more cars.
A funny thing happened when Henry put shock absorbers on all his cars, he sold and sold and sold more cars.
Henry sold so many cars that all the world car manufacturers now put shock absorbers on their cars.
We reckon your caravan needs them too.
