This item has been a hit for all of our motorcycle carrier vans. 100% tig welded aluminum means it's up for the task of keeping your brand new bike off your van or trailer floor. Slotted mounting tabs give you the ability to mount this wheel chock at different angles. This is a must for loading multiple bikes in the back of a Sprinter, Transit, or ProMaster van. Add modularity by mounting it to L-track in your floor. Our L-track studs will help lock it down!
