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:
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.
Warranty is available on all shocks.
BOSS Global also has developed threaded 12 position adjustable dampening coil-over shocks for the IRS front suspensions found on Toyota, Mitsubishi, Nissan, Ford and many other 4x4 off-road and 2wd on-road vehicles.
Currently these are available in 2 lengths with billet aluminium 2 pc reversible spring seat. End fittings to suit each vehicle vary in price depending on application.
*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. When the fittings are installed they require a threadlocker compound.
