Moto-Chok Extender

Moto-Chok Extenders

Does not include Moto-Chok. Moto-Choks sold separately.

Need to push your Moto-Chok out past a rolled-up tonneau cover, clear wide handlebars, or just create a little extra room in your truck bed? Our Moto-Chok Extenders are built for the job and are available in 3″, 5″, 7″, 9″, and 12″ lengths (custom sizes available on request).

Unlike the Z-TRAK Extender, which uses an E-Track plate to clip in and out separately, Moto-Chok Extenders bolt directly to the Moto-Chok. This creates a solid, one-piece assembly with less rattle and movement, while still allowing the extender + Moto-Chok to clip in and out of your Z-TRAK or High Strength E-TRAK rail together as an assembly.

How Sizing & Depth Measurements Work

To help you choose the correct extender length, here’s how measurements are calculated:

• Z-TRAK and High Strength E-TRAK rails add approximately 1/2″ of depth from the original mounting surface.

• When an accessory is clipped into the rail, the distance from the original mounting surface to the back face of the clipped-in accessory is always ~1 1/4″, regardless of extender length.

• Extender length is measured only by the extension bar itself.

• The listed extender length does not include the depth of the Z-TRAK / E-TRAK rail or the clip plate.

✅ This means the total depth at the face where the Moto-Chok mounts will always be ~1 1/4″ longer than the listed extender size.

Total Extension Depth Reference (Approx.)

Measured from the original mounting surface to the Moto-Chok mounting face:

• 3″ Extender → ~4 1/4″ total depth

• 5″ Extender → ~6 1/4″ total depth

• 7″ Extender → ~8 1/4″ total depth

• 9″ Extender → ~10 1/4″ total depth

• 12″ Extender → ~13 1/4″ total depth

Why Choose Moto-Chok Extenders

• Versatile fit: Multiple lengths to handle different truck and bike setups

• Rock-solid connection: Bolts directly to your Moto-Chok for reduced vibration

• Easy in/out: Extender + Moto-Chok clip in and out together

• Custom builds available: Need a different length? Just reach out

If you prefer a more modular setup that lets you clip the Moto-Chok on and off separately, check out our Z-TRAK Extender. But if you want a clean, bolted-together extended Moto-Chok setup with more length options, the Moto-Chok Extender is the perfect choice.

⚠️ Will not work with Bike Choks. Bike Choks use a special plate — please use the Z-TRAK Extender for Bike Choks.
