In order to provide you with innovative and high-quality products that offer superior support, we have integrated the Collins family of products into the B/A lineup. This grants you access to the best freight policy in the industry. We have the new Collins SLX High-Speed Dolly available with over 25 dynamic design improvements to provide you with the right amount of support needed to easily maneuver the disabled vehicle. Its load bearing pivot points run through the dolly body, and it has welded end caps for added strength. Its two-tone zinc plating is standard on all steel components, which gives an improved resistance to salt corrosion and winter chemicals. The rail ends are single-piece construction. The Collins Dolly is the most serviceable dolly around since you can easily replace components on the spot. We carry the right replacement wheels and tires along with replacement dust caps and bearings to keep the dolly working optimally.
