J-TECH Boxxer World Cup Negative Air Spring Housing

Transform your Boxxer air spring to a 'coil like' feel, without the weight penalty!

 The J-TECH Boxxer Negative Air Spring Housing replaces the existing parts in your 2011-2014 RockShox Boxxer World Cup. It works by increasing the air volume of the negative air chamber, thus acting against the positive air spring further into the travel. This gives the fork a much more linear feel through the first 75% of the travel, with a nice progression for the last 25%.

 We know that everyone likes a different feel, so we've made the air volume adjustable by means of fitting volume tuning o-rings. The more o-rings fitted, the firmer the fork will feel in the first part of the travel, just add or remove to your desired feel, it's as simple as that!

 The housing comes complete with o-rings ready installed for fitting and a selection of tuning o-rings. It's as simple as removing the existing housing from your fork and replacing with the new housing, along with your preferred number of volume tuning o-rings.
