Overload protector - prevents overstressing of material  
 
-
(over   stressing decreases the response curve).
Longer life - High quality seals used throughout for longer life.
 
-
Minimal Friction - The piston valve is manufactured in 
 
-
chromated sintered material. This minimises friction and the 
accumulation of dirt and also considerably increases shock 
absorber life.
Temperature resistance - AL-KO uses a specific oil which is  
 
-
unaffected by temperature. Chemical additives prevent the 
formation of bubbles and inhibit noise.
COMFORT AND ASSURANCE
For unparalleled levels of comfort and assurance AL-KO has created the Octagon Shock Absorber range. A selection of 
four, colour coded devices provides the optimum level of support and damping for your trailer or caravan.
Shock absorber technology unique to Octagon suppresses the effects of uneven road surfaces providing a smoother, 
more enjoyable ride. With an improved ride comes additional support for the caravan or trailer, vastly increasing 
stability and road holding ability.

							HOW TO FIT AL-KO SHOCK ABSORBERS
1 Use a screwdriver to pry 
out the plastic cap on the 
underside of the swing arm, 
revealing the hole for the 
shock absorber brackets. 
Some chassis may already 
have the brackets welded in 
place. If so skip to step 5.
2 Take the two brackets from the 
shock absorber kit.
3 Open up the brackets and hold 
them so the top edges are 
aligned, and slot them into the 
hole under the swing arm. 
4 Pull the brackets together 
to lock them in place. Check 
the brackets are correctly 
positioned by ensuring the 
arrows engraved into the 
brackets are pointing to the 
front of the trailer or caravan. 
Note that there will be a gap at 
the bottom of the two brackets.
5 Take the shock absorber, and 
with the coloured section at 
the top, and black section 
at the bottom, insert the top 
screw into the middle hole on 
the chassis and secure with 
an M12 lock nut.
