Mono tube high pressure gas charged shock absorbers 55 Series
Patented mono-tube valving plus high pressure nitrogen gas account for ride comfort and eliminate the aeration or foaming that can occur in twin tube shock absorbers.
These are a very good quality high pressure gas charged / velocity sensitive performance style shock absorber. A good alternative, where available, for “high load” applications such as commercial vehicles.
The high gas pressure has the ability to control higher than normal spring rates such as those found in the rear of commercial vehicles. Particularly useful in controlling these high spring rates when in an “unladen” situation.
