Now there's a SuperGlide for everyone! PullRite proudly introduces its new SuperGlide fifth wheel hitch that fits "industry standard" heavy duty base rails! The #2300 ISR is designed for towing those bigger rigs. With a gross trailer weight of 24k pounds, this Industry Standard Rail SuperGlide out-performs other foreign-made hitches of the same class. The #2300 can be ordered with our "better than theirs" Industry Standard Universal Base Rails or simply keep the ones you have already in your truck bed. Fully automatic! It's a huge upgrade, at a small price -- and the best choice possible for many short bed truck owners!
