A good fit

  • Width: about 1/4" of mouthpiece should show on each side of the mouth. Measure across the mouth at the corners, or check the size on a bit that fits now.
  • Height: adjust the headstall so the bit makes one or two soft wrinkles at the corners of the mouth.
  • Curb strap: fit two fingers between the strap and the chin. It should engage when the shanks rotate back about 45 degrees.
  • Leverage: longer shanks and a longer purchase give more leverage, so match the bit to your horse's training.

Questions, answered

What does a combination bit do?

A combination bit pairs a mouthpiece with a rope or chain noseband, so pressure is shared between the nose, chin and mouth. The noseband usually engages first, which many speed horses like.

What is a gag bit?

Gag bits have sliding cheeks, so the mouthpiece rises in the mouth when you pick up the reins. They are popular for elevating the front end and rating speed.

What size bit do I need?

Most Quarter Horses take a 5" mouthpiece, smaller horses and Arabians 4 3/4", ponies 4" to 4 1/2" and minis 3 1/2" to 4". About 1/4" should show on each side of the mouth. Measure across the mouth at the corners, or check the size on a bit that fits now.

Do shank bits need a curb strap?

Yes. Shank and gag bits work with a curb strap or chain. Adjust it so two fingers fit between the strap and the chin.

Yes. Regularly priced items can be returned or exchanged within 30 days of purchase if they are new and unused, with original tags and packaging (domestic orders, $30 minimum). Sale and discounted items are final sale. See our Shipping & Returns page for details.
