Built Like a Mammoth
Why a mammoth? Because it carried impossible weight across the world’s harshest terrain — and so does our hardware.
Every GAMMA 4X4 damper is engineered and tested to take the load, mile after mile: from Outback corrugations and Middle East dunes to alpine rock crawls. When your customers bolt on a GAMMA shock, they bolt on strength they can build a reputation on.
