Our line of bespoke pistons from Traum bring the highest quality and best available specification to the A-Series platform.
 
No longer will you struggle to achieve your target compression ratio, our standard offerings are designed around a cylinder head chamber size of 24.5cc which allows for preferential shaping of the chamber without sacrificing gas flow and combustion "squish".
 
These pistons set a new standard for weight and quality, substantially lighter than others on the market and delivered to you balanced to within 0.1g of each other
 
Supplied with 18mm fully floating pins and Wire Lox retainers suitable to suit high power outputs.
 
Ceramic Crown Coating
 
This coating reflects heat into the combustion chamber and away from the piston crown, while lowering piston temperatures for increased part life. The engine can experience improved combustion and performance as a result of heat being reflected back into the fuel charge.
 
Moly Skirt Coating
 
The application of molybdenum to the piston skirt, used to reduce friction between the piston and the cylinder during engine operation. It also helps during cold start ups and high temperature operation where a substandard oil barrier on the cylinder wall could exist.
 
Available with a range of custom Dish sizes where required.
 
Some pistons are made to order and have a lead time of between 8-10 weeks (+2 weeks for coatings) Please contact us for exact timelines before ordering.
