TracTive Dynamic (DDA) Plug & Play ESA shocks are specially designed for the original BMW ESA equipment. The shock itself is 100% new, only the spring preload motor is harvested from your original shock.

The engineers at TracTive invented ESA for BMW back in 2005, and they have a patent on their superior dynamic damping valve so you can count on their system functionality. 

TracTive ESA conversion benefits include:

• Stainless steel reducer bushings (where the bolts pass through the mounting eyelets). Other companies use aluminum which is a softer material, and can contract or deform shape over time

• The same reinforced seal head as used in the TracTive Adventure bike shocks. This seal head is very robust, provides long life, and rarely develops leaks

• 46mm pistons with16mm induction hardened, chro-moly shafts. 

• If your original preload motor ever fails, a TracTive electronic preload motor can be installed which makes this shock withstand the test of time.
