Trim-to-Fit saddle fit shims are available in a 3/16″ | 4.8mm thickness of amazing shock-absorbing protection.

4 styles of Saddle Fitting Shims can be made from our Trim-to-Fit shims.  All shims come in pairs.

  • Trim-to-Fit Shims –  This pair of full-length shims meets all of your shimming needs! Trim to create a pair of Front, Bridging, and Rear Saddle Fitting Shims or use as a single shim to Boost your overall ThinLine protection and comfort.  Simply use scissors or a box blade to trim.
  • Shims stay put without shifting and you may stack up to three sets. We do not divide the pocket on your pad, allowing you or your saddle fitter to place the inserts precisely where your horse needs them.

If you find you no longer need inserts, just remove them and keep all the great benefits of your ThinLine Pad!

We have a list of saddle fitters on our dealer page if you would like to consult with a specialist.

    Diamond line standard trim to fit saddle pad shims.
    Have been trying a few different saddle pads and none fit as good as the Thin Line and use the trim to fit shims. It fits great, stays in place and my horse is comfortable so I’m happy!
    I won’t be looking for another pad!
