Many Jeeps, trucks and SUVs have upgraded or aftermarket bumpers with shackles (or 'D' tabs) and D-rings. Instead of installing a baseplate, you can pin your tow bar directly to your bumper shackles. These kits will adapt Roadmaster motorhome-mounted tow bars (will not work with Stowmaster or Tracker tow bars). Simple installation as the adapters replace the ends of your existing Roadmaster tow bar arms. The 035 Adapter is made with heavy-duty drop forged steel for added safety and strength. Coated with a durable powder finish for increased durability. The 035-1 Adapter fits a 3/4" thick D Tab & Shackles with 1" diameter holes. Important! Before using these adapters, confirm that the bumper manufacturer has approved it for flat towing. Not all bumpers will withstand the rigors of flat towing.
