Western Curb Bits & Curb Straps

Western Curb Bits for Trail Riding, Ranch Work, and Western Performance

• Stainless steel construction: Rust-resistant stainless steel shanks and hardware hold up through wet conditions, daily barn use, and heavy arena work.
• Copper mouthpiece inserts: Copper rollers and inlays encourage salivation, promoting a softer, more responsive mouth and better rein contact.
• Multiple shank lengths: From short shanks for lighter leverage to longer shanks offering amplified rein signal — matched to horse training level and discipline.
• Curb straps and chains included: Collection covers full curb systems — nickel-plated chains, latigo leather straps, nylon-braid slobber bars, and harness leather options.
• Wide range of mouthpiece styles: Single-jointed, dogbone, twisted wire, U-shaped correction, medium port, and tongue-relief designs across 140+ SKUs.

How to Choose the Right Western Curb Bit for Your Horse

Shank Length and Leverage

Shank length directly controls leverage ratio — longer shanks like the 7" and 7.25" options in this collection amplify rein pressure, making them better suited for trained horses with a soft mouth. Shorter shanks and Argentine-style cheeks offer milder leverage and are a common choice for horses transitioning from snaffle to shanked bit work.

Mouthpiece Style and Horse Sensitivity

Single-jointed mouthpieces are familiar and widely used for general western riding. Dogbone and three-piece designs distribute pressure more evenly across the tongue and bars. Correction bits with U-shaped mouthpieces offer tongue relief, while twisted wire mouthpieces provide sharper signal — best reserved for experienced hands and well-trained horses.

Curb Strap Material

Leather curb straps — latigo, harness leather, and American leather options in this collection — sit softly against the chin groove and are a traditional choice for show and trail. Chain curb straps offer firmer, more consistent pressure and are common in ranch and working settings. Nylon-braid slobber bars sit between these two in terms of firmness and are easy to clean.

Common Mistakes When Buying Curb Bits

Choosing too much leverage for a green horse is the most common error — long shanks require a well-trained, soft mouth. Riders also frequently overlook mouthpiece width: a bit too narrow pinches the lips, too wide slides side to side. Finally, pairing an aggressive mouthpiece with a chain curb strap compounds pressure — match severity carefully to your horse's training level.

Why Copper Mouthpieces Make a Difference in Western Bits

Riders who switch to copper-inlaid or copper-roller mouthpieces consistently report a more relaxed jaw and lighter rein response. Copper is slightly warmer to the touch than plain steel and oxidizes in the mouth, producing a mild taste that encourages the horse to mouth the bit and produce saliva. A salivating horse carries the bit more comfortably, stays lighter on the rein, and is less likely to brace or set against the rider's hand — a noticeable difference during long trail rides or extended arena sessions.

Tom Thumb vs Shank Correction Bit vs Argentine Snaffle — Which Curb Bit Is Right for You?

Tom Thumb Bit

The Tom Thumb combines a single-jointed snaffle mouthpiece with shanks, creating both direct rein action and curb leverage. Available here with 6" and 7" shank options and copper mouthpieces to encourage salivation. Best for: horses moving from a snaffle into shanked bit work under intermediate riders.

Shank Correction Bit

Correction bits feature a U-shaped or ported mouthpiece that relieves tongue pressure while providing clear directional signal through the shanks. The copper inlay versions in this collection are built from stainless steel with nickel or antique finishes. Best for: trained horses in ranch work, trail riding, or western performance where refined lateral control is needed.

Argentine Snaffle

Argentine-style cheeks offer mild leverage with some independence of rein action, making them one of the gentler shanked bit options. Available here with single-jointed and three-piece dogbone copper mouthpieces. Best for: younger horses transitioning off a ring snaffle, or sensitive horses in light western riding and trail work.

A snaffle bit acts with direct rein pressure on the corners of the mouth with no leverage. A curb bit uses shanks to create a lever effect, applying pressure to the poll, chin groove via the curb strap, and the mouth simultaneously. Curb bits require a horse with more training than a snaffle, as the amplified signal demands a softer, more responsive mouth to avoid over-cueing.

Most adult horses fit a 5" mouthpiece. To measure, use a smooth dowel or a bit you know fits, place it in the horse's mouth, and measure between the cheek pieces where it exits each side — you want roughly 1/4" clearance on each side. Ponies and small-mouthed horses typically need a 4" or 4.5" mouthpiece. This collection includes options from 4" pony sizes up to standard 5" horse sizes.

A Tom Thumb is technically a curb bit because it has shanks and uses a curb strap to create leverage. Despite having a jointed mouthpiece similar to a snaffle, the shanks change how rein pressure is applied — introducing poll pressure and chin groove pressure in addition to mouth action. It should not be used on horses that have only been ridden in a snaffle without a proper transition period.

Leather curb straps — including the latigo and harness leather options in this collection — are softer against the chin groove and a good choice for horses with sensitive skin or for show use. Chain curb straps deliver more precise, consistent pressure and are preferred in ranch and working situations. Either way, proper fit is critical: you should be able to fit two fingers flat between the strap and the chin groove when the bit is at rest.

After each ride, rinse the mouthpiece with clean water to remove saliva and feed residue. Dry with a soft cloth to prevent water spots. For stainless steel shanks, a light wipe with a damp cloth is sufficient — stainless resists rust without oil. Copper mouthpiece areas can be cleaned with a copper-safe cleaner to remove tarnish. Inspect joints and rings periodically for wear or burrs that could create rough edges against the horse's mouth.

For trail riding, a medium-shank bit with a low port or dogbone mouthpiece is a practical choice — enough leverage for control on varied terrain without being overpowering on a relaxed trail horse. Argentine snaffle-style shanks with a three-piece copper mouthpiece work well for horses that need gentle guidance over long distances. Pair with a leather curb strap for comfort on extended rides where the horse is wearing the bit for several hours.
