About AST & MOTON Suspension

Suspension is one of the biggest impact upgrades you can do to your vehicle. Ride height makes a huge visual impact, and changing spring rates and dampening has a huge impact on ride quality and handling. We always recommend that our customers pick a quality suspension system when looking to lower their vehicle/upgrade their suspension.

AST & Moton are world renouned in the world or motorsports. They offer the same technology used in their race winning suspension systems in their street focused systems.

The company was founded in 2000 by Piet Kreeft and Peter Smits combining their expertise to innovate and manufacture new suspension systems. AST made its name through unparalleled quality control and manufacturing flexibility, setting them apart from many other companies in the suspension industry.

With over 2 decades of experience with companies such as Koni and HI TECH, Kreeft and Smits have deep roots in the suspension world as well as motorsports. Working with race teams in WRC, Dakar Rallies, Indy Car, and many other Kartcross and Touring car events, both bad a wide knowledge of performance suspension tuning.

In 2011 AST purchased MOTON Suspension Technology. MOTON is a renowned damper brand founded in 1999 that develops, manufactures and markets a full range of high quality, state-of-the-art adjustable dampers. By 2000, 30% of the starting field in the 24 hours of Le Mans were equipped with MOTON dampers.

Both AST and Moton have become providers of high performance shock absorbers used by many prominent manufacturers and racing teams worldwide. MOTON’s applications are mainly used in GT and Touring cars as well as in high-performance street cars while providing user-friendly and efficient technology.

Design Philosophy

AST designs their suspension systems with the focus on strength, reliability, and performance.

Most AST and All MOTON Dampeners utilize a mono tube design with high quality, low friction seals and bearings. This design offers cavitation resistance and control over larger oil flow and damper movements.

Larger Pistions add to improved oil flow and greater sensitivity to small damper movements, better adjustment range, and increased lateral strengh.

Inverted Piston design and External reservoir on AST high end systems both increase damper strength in all directions as well as help eliminates overheating and cavitation.

Where do you want to Finish?

AST & MOTON Suspensions were bred through motorsports and competition. Many professional races have been won on MOTON dampers such as the FIA GT and FIA Sportscar Championship, FIA ETCC and FIA WTCC Championship, Grand-Am and World Challenge Championship, and as well as numerous National GT, Touring and Club Racing events all over the world.

So when it comes time to pick the right suspension for your vehicle, it is important to ask yourself...Where Do You Want to Finish?
