AST 4200 Monotube Double Adjustable Coilovers for 1M and M3

Here is our AST 4200 with Swift springs and Vorshlag camber plates for our project 1M.

Shown with optional adjustable front strut mount, rear quick change spring kit(with helpers and radial thrust bearing) and remote rear rebound adjusters.

The 4200 Series shocks use AST’s Twin Piston Dual Adjust (TPDA) technology. Similar non adjustable versions have been found in the highest forms of racing. TPDA builds on this technology to allow for 2 adjustment knobs to be mounted on the shock body (no tools required). Quick rebound and compression changes can be made in the pits in seconds. 4200s are fully customizable and rebuildable.

AST-USA offers full rebuilding and revalving services for AST shocks at competitive prices. This includes quick turn around when you need it the most.
Benefits include:
Monotube design - gives the biggest piston sizes available
Floating piston design with high pressure nitrogen means no cavitation around the piston
Compression and Rebound adjuster knobs permanently mounted on the dampers – no fumbling for knobs
Fully threaded strut bodies allow maximum tire width without fender rolling or larger spacers
Rebuildable by AST-USA – get the valving you want, when you want it.
