Are you the most serious person on the race track? Get to a winning setup by using all options that our 3-way adjustable dampers have to give. All adjusters work completely independently. Once installed the shock absorbers are easy to setup, highly reliable and require low maintenance during the season because of the high grade of materials used. Tested on tracks like the Nürburgring, Zandvoort, Imola, Laguna Seca, Macau and many others around the world.
For the best performance on the track, AST Suspension designed the Competition 3-way adjustable series. The 5300 Series shock absorbers are rebound adjustable in 12 positions on the strut.
The high speed compression is adjustable in 12 positions and the low speed compression is adjustable in 14 positions. Both compression adjustments are made using an external canister. All adjusters work completely independent.
Many years of technical knowledge, testing and experience has been refined, fettled and brought together to create a perfect balance between the choice of springs and the corresponding damping characteristics. This makes it a versatile product for every customer. The 5300 series shock absorbers are the best solution for every race team. Once installed, the AST shock absorbers are easy to setup, highly reliable and require low maintenance during the season because of the high grade of materials used.
All of this together makes the 5300 series shock absorbers a championship winning damper, over and over again. The AST 5300 Suspension is worldwide renowned for its performance at every level.
