Overview: Up and down travel are huge adjustments, with one taking place outside the shock and another, inside the shock. JConcepts has refined lightweight injection molded spacers in multiple increments to make solid vehicle adjustments. First, the down travel limiters are precision molded in 1, 2, 3, and 6mm lengths to achieve a wide range of options. The outside limiters, included in the same length, are clip based with a small opening so adjustments can be made on the fly to the outside. In addition, some vehicles use clip based, shock, ride-height adjusters such as the Traxxas Slash, Rustler, Stampede, Bandit, Drag Slash, Slash 4x4, Rustler 4x4, and Stampede 4x4. JConcepts has included an assortment of extra clip-in ride height adjusters so even more tuning can take place or simply replace something that is missing after an extreme bashing fest. The set is available in multiple colors and includes 24 total pieces making it a fine item to add in any toolbox. This combination of items is ideal for all 1/10th and 1/8th shock tuning using either 3.0 or 3.5mm shock shafts. The possibilities keep off-road, carpet, drag racing, and on-road racers on pace with the competition to tailor shock adjustments with the experts. For bashers, the included clip style, right height adjusters help regain stock form or get right-height just where its preferred. The product is always backed by JConcepts customer service, supported, and developed by professionals with style and authenticity. JConcepts is, World Proven Innovation and Design – since 2003.
