FSLI4 and FSLI4/ST calipers provide the pad wear performance advantages of differential bore pistons with the option for ultimate heat protection using Thermlock pistons in the ST models. Differential piston bores compensate for leading-edge mechanical loading and temperature variances across the pad face to reduce pad taper wear in sustained high temperature applications. Thermlock pistons in the ST models block heat transfer from the pads and reduce temperatures in the caliper, fluid, and seals by up to 25% over standard stainless steel pistons. These are the go-to calipers for all types sustained hard braking on dirt and asphalt ovals and a wide range of off-road, rally and road course applications.Shipping Notes

Dogs love them
Flavor Name: Beef, Size: Small
My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!

Durable Nylabone That My Dog Loves
Size: Large
This Nylabone chew toy is a winner! My dog absolutely loves it and has been chewing on it daily for months, and it’s still holding up great. The durability is impressive, especially compared to other toys that don’t last nearly as long. It’s become my dog’s favorite chew toy, and I love that it keeps him entertained without wearing out quickly. Highly recommend for any heavy chewers!

Worth the money
Size: Large
My dogs love these! I was buying them on Chewy, but there a little cheaper on Amazon. I guess they're flavored because both of my dogs love to chew on them. They hold up pretty well too.

My dog loves this
Size: Large
This was a great product for a chewer dog.
My Pitt bull chewed this toy for a long time. My only complaint would be in the process of chewing some areas became pointy and cut his gums slightly. It didn’t seem to bother him but the blood on the white toy was disturbing to me.
