Air shock, mono tube high pressure adjustable nitrogen charged.

Terrafirma Air shock, mono tube high pressure adjustable nitrogen charged with a 40mm shaft, 60mm piston and 66mm body.

Developed originally for competitive rock crawling buggies where extreme axle articulation means everything. Terrafirma's new Profender 2.5" Air shocks support the weight of the vehicle, provide infinite ride height adjustability and allow massive articulation for custom vehicle builders.

No more problems with coil springs dislocating or becoming coil bound restricting wheel movement. With a range of travel options these Air shocks provides ample axle movement even for the most extreme off road competitors. The ride quality experienced with air shocks is exceptional, combined with Terrafirma hydraulic bump stops obstacles and extreme terrain can be attacked like never before.

The Terrafirma / Profender Air shock is super strong 2.5" (66mm) diameter and uses a massive 1.625" (40mm) hard chromed highly polished piston shaft with the latest technology valving and seals. Air shocks are charged with high pressure Nitrogen, factory set at 150psi and adjustable between 100 and 400psi depending on the weight of the vehicle and preferred ride height.

Air shocks are designed to be mounted vertically with the shaft at the bottom for optimum performance.

These units are fully rebuildable and tuneable using off the shelf parts that we carry in stock - spare schrader valves, o-rings etc so you can carry out field repairs during a race event.
