ISRX Series Super 5th and SuperLite
An OEX-type hitch that mounts to ISR Rail equipped trucks!
Interchangeable coupler options!
Buy one configuration and if you prefer a different coupling method down the road, swap out the coupler without the cost of buying a new hitch!
The illustration and animation below shows how you gain 4" of additional cab-to-trailer clearance. To watch an instructional video on how to change the offset on either an OEX or ISRX hitch, click here!

ISRX offers more cab-to-trailer clearance than any other brand!
The ISRX base provides both Super 5th and SuperLite with an 4" additional cab clearance as seen above. ISRX SuperLite's King Pin Adapter, gives you an additional 3.5" of rearward offset for a total of 7.5"! That's more than you'll get with any other brand!

» ISRX SuperLite provides an additional 7-1/2” cab clearance
Below we have provided illustrations to show the approximate amount of additional turning degrees the ISRX Series hitches will provide.
NOTE: We are demonstrating the degrees of turn possible with a squared-cornered trailer; if you have cutaway corners on your trailer, you are likely to get an even greater angle of clearance! The angles given here are the point at which the trailer will make contact with the cab. Point of contact based on 96” wide trailer on flat ground.
