High Wind Shock Absorber Kit For UTRF Model Trackers The shock absorber is manufactured exclusively for Zomeworks. Its dampening effect is 50 times as strong as that of the shock absorber used for our line of smaller UTR trackers. Hang on it and it just creeps, moving only an inch or so in a minute. This new shock absorber is standard for all F-Series trackers. The UTR 020, 040, 055, 070, 085, and 100 trackers do not have enough force to compress the ZW 2003 shock absorber. Shocks are included in this kit, or you can order them seperately - see ZW-2003S. ZW-2003 Shock Absorber High Wind Upgrade Kit: The High Wind Upgrade Kit is recommended for stabilizing the tracker in areas where there are frequent high winds. This kit can be ordered with your tracker or purchased later as an add-on. The High Wind Upgrade Kit consists of an additional set of ZW-2003 shock absorbers, a T-Bar for mounting the shock absorbers and a bumper bolt to protect the shock absorbers from the tracker rails. The High Wind Upgrade Kit is only available for the larger Track Racks.
