EXT's V4 is the pinnacle of MTB suspension technology, bristling with new features and small improvements from the V3. 

On the compression circuit we have the internally tune-able LOK we are familiar with from the V3 and we have a similar compression adjustment assembly but now with 4 and 5mm allen adjustment for LSC and HSC for ease of trail-side adjustment.. There is a new HBC system with a greater range  and a new adjustment capability so you can tailor the amount of HBC which covers the final 20% of the travel... All with a 4mm allen key. All the compression side adjustments on a multitool...

On the rebound side we have a Position Sensitive Rebound which acts as a hydraulic rebound stop to completely eliminate top out and a greater adjustment range.

The spring collars feature thrust bearings for sensitivity and increased clearance between body tube and springs for less rub in the mud...

A low pressure bladder system for increased sensitivity off the top

New low friction, long lasting coatings for both body tubes and shaft, The shaft is DLC chrome steel, tough as!
