Lock Body Clamp Kit

This kit includes everything you need to change the CRC System clamps to a keyed locking configuration.  Be sure to check your rack clearance before purchasing this kit.


  • Two lock bodies with key cores
  • Two hand knobs
  • Two keys

required crossbar clearance

It is important to check the clearance between your vehicle's crossbars and the roof of your vehicle. This is to ensure that there is adequate space to install the lock body clamp kit. Some popular crossbar examples are shown below for reference.

Yakima Aero Bars

Rhino Rack Bars

Round Bar (Yakima 1-1/8" Diameter)

Square Bar (Thule Bars and Others)

Notes On Other Crossbar Dimensions

Some factory aerobars are very low and close to the roof of the vehicle and extremely thin. Our standard and XL clamps now come stock with low profile mounting hardware to accommodate this popular style of roof rack.

Depending on your crossbar size and selection you may require the XL clamp. You can use our clamp size selection tool on the CRC System page or simply send us an email with details on your rack.

*Please contact us if you have a unique or odd cross bar system and we will do our best to get you up and running.

Better than expected

Wasn't sure how well they would actually work but turns out hey are much better than the hardware that comes with the CRC. Don't know why they are an option.

Jeffrey Hayward
Lock Body Clamp Kit

I highly recommend these clamps. Easy to install and lock/unlock. I feel my rod(s) are safe when I’m in the water. Well worth having.

This sturdy and secure lock system gives me peace of mind, especially when parked at my out of the way river destinations!
