BOSS 12 way adjustable shock absorbers are at the forefront of shock absorber technology. 100% oil filled with a closed cell foam insert ensure continued high performance under harsh conditions. Why 100% oil filled as opposed to gas/oil? It all comes down to cost. Gas/oil shocks are cheap to make because the nitrogen, (which is one of the cheapest gases around), takes the place of where oil should be (oil costs more).

If you pull one of these shocks apart you will notice there is only just enough oil to cover the piston and valve, once this small amount of oil gets hot it relies on the gas pressure to stop it aerating. The higher the gas pressure the more chance the shock will not work at all when it gets hot because the pressure forces the valves open (even pressure both sides also called cavitation).

BOSS shocks will not fade under hard use, the piston and bypass tube is continually submerged in oil, keeping it cooler and displacing heat through the walls of the shock.

BOSS shocks are the only shocks on the market with 12 adjustable settings for rebound dampening. This allows a huge range of adjustment for vehicle type, weight of vehicle and other changing factors. On the harder settings compression dampening is also affected however the main purpose of a shock absorber is to control rebound dampening, the springs are for compression!.

BOSS shocks are of “twin tube” design, this is for several reasons:

 
1. The bypass tube for the rebound adjuster must return up the side of the shock, this goes between the piston sleeve and the outer case.
2. Second is durability off road, if a mono-tube shock gets rock damage to the body the piston will simply jamb wrecking the shock. Our twin tube shock can sustain extensive damage to the outer case before the working of the shock is affected.
3. Thirdly the second skin of the shock allows more room for oil, more oil attributes better heat displacement.
4. And finally the twin tube design facilitates the closed cell insert which is there to compress when the shock shaft is inserted.

BOSS shocks use a 22mm hard chrome shaft, dual seals (wiper and oil) along with 50mm outer body. BOSS shocks are the ONLY shock in the world to offer 17 lengths to suit ANY vehicle. This is achieved by having female threads at each end allowing the customer to install any fittings needed at each end to suit the application. Once fitted the shock can be adjusted to suit the vehicle and weight via the 12 position adjustment.

The lengths are listed below. We have shock lengths up to 1000mm extended. We believe BOSS Global to be the only company in the world to offer shocks this long.

12 Month / 20,000 KM Warranty is available on all shocks.

BOSS 12 Way Adjustable Shocks

*NOTE: The part number corresponds to extended and compressed length on the shock. i.e. 559 is equal to 559 mm compressed and 1000 is equal to 1000 mm extended. This is measured from the base of the shock to the end of the shaft. When fittings are installed (pin or loop) they add a total of 54mm to the overall length. All fittings and bush’s are included in the price. Optional rubber protective boots are also available at no extra cost.
