BOOST VALVE® IS FOX’S PATENTED POSITION SENSITIVE DAMPING TECHNOLOGY,<br />
WHICH COMES IN SEVERAL DIFFERENT APPLICATION SPECIFIC CONFIGURATIONS:<br />
• BOOST VALVE DAMPING CAN BE UTILIZED IN THE BEGINNING OF THE STROKE TO ACHIEVE PROPEDAL<br />
peDALING EFFICIENCY.<br />
• BOOST VALVE DAMPING CAN BE UTILIZED AT THE END OF THE STROKE TO PROVIDE A BOTTOMLESS FEEL AND<br />
cONFIDENCE INSPIRING ENDING STROKE CONTROL.<br />
• BOOST VALVE DAMPING CAN BE UTILIZED THROUGHOUT THE STROKE OF THE SHOCK, PREVENTING SUSPENSION<br />
OVERSHOOT AND UNWANTED RIDER-TERRAIN INDUCED MOTION.<br />
After years of developing and racing Boost Valve equipped shocks we’ve garnered an understanding of where<br />
and how to apply this versatile and high performance tool. The result, a new from the ground up DH shock, the<br />
FOX <strong>DHX</strong> <strong>RC4</strong>. The FOX <strong>DHX</strong> <strong>RC4</strong> utilizes Boost Valve position sensitive damping for the last 1/3rd of the shock<br />
stroke where the confidence to launch big, or the control when a landing transition is not perfectly hit, can be the<br />
difference between winning and merely staying upright.<br />

The integration of Boost Valve technology into our FLOAT RP shock family<br />
is an entirely new application for this precise race oriented tool, mating our<br />
World Cup proven Downhill technology with our lightweight FLOAT chassis<br />
for increased rider control, traction and bottom-out resistance.<br />
These FLOAT shocks maintain ProPedal pedaling efficiency and the intuitive<br />
adjustment scheme you’ve come to know and love in the RP23, and<br />
then make bumps disappear and jump landings seem tame. Making this<br />
the only shock on the market combining this level of light-weight pedaling<br />
efficiency with gravity inspired bump eating performance and control.<br />
