Ohlins TTX40 MkII Motorsport Damper External Reservoir - Universal - Single, No Spring
The Öhlins TTX40 MkII is a genuine top level racing damper, proven in Le Mans, Indy Car, touring car and GT competition. Its twin tube, through rod design is fully independent 4-way adjustable, giving race engineers precise control over compression and rebound without the compromises of a standard damper. This external reservoir version separates oil storage from the damper body, improving consistency under sustained track loads.
This listing covers the TTX40 MkII external reservoir damper, sold as a single unit in the 207.6/48 length configuration under SKU TTX-NH01. It is supplied without a spring and is designed for universal motorsport fitment rather than a specific chassis. Additional lengths, including 321.6/80, 390.6/100 and 480.6/130, are available through the variant selector on this listing.
Note: This damper is sold individually and without a spring. A second damper and matched springs will need to be ordered separately to complete a full corner or axle set.
