Cross-Drilled & Slotted Rotors

Stoptech Cross-Drilled & Slotted rotors are 1-piece, drilled and slotted, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Stoptech Cross-Drilled & Slotted covers more than 2500 applications, all machined in Stoptech Cross-Drilled & Slotted California manufacturing center. Every Stoptech Cross-Drilled & Slotted rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

Most Stoptech Cross-Drilled & Slotted rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Stoptech Cross-Drilled & Slotted has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

Every Stoptech Cross-Drilled & Slotted rotor is finished with a black e-coating on both sides of the hat, inside the cooling vanes and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral runout issues.

Stoptech Cross-Drilled & Slotted rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

Stoptech Cross-Drilled & Slotted rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

 

Stoptech Cross-Drilled & Slotted brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

 

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

 

Power Alloy metallurgy is another unique feature in many of Stoptech Cross-Drilled & Slotted's rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Stoptech Cross-Drilled & Slotted's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Stoptech Cross-Drilled & Slotted's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).

Great for Slowing Down Snack Time
Size: Large (Pack of 1), Product Packaging: Standard Packaging
My dog, an English Lab, is a voracious chewer, and destroys most toys in a matter of seconds. He also swallows most snacks without even chewing, and finishes meals in record time. It takes him about 20 minutes to get everything out of the Kong, and since I hide it somewhere on our property, he also takes several minutes to find it. He seems to really love the challenge, and it’s nice to have him take more time with a snack. I tried the Kong Easy Treat to seal the toy, but I find peanut butter works just as well (especially when frozen after being filled and sealed), and it’s cheaper and easier to use.

This product actually lives up to the title of indestructible.
Size: Large (Pack of 1), Product Packaging: Standard Packaging, Size: Large (Pack of 1), Product Packaging: Standard Packaging
This is the only toy I've had which my dog hasn't destroyed in minutes. I have had a few others that will at least last a few months, but Kong extreme has held up over the years. I like the fact that I can stuff it with treats, bits of other "indestructible" toys and seal it up with peanut butter, then pop it in the freezer to give her an extra 15 minute challenge. I have a couple so I can clean one while she's busy with the other. This size seems to be the best for a ~90lb. dog, the large end being roughly the same size as a tennis ball, which she loves as well.

Great product but choose a size or two up
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Nice quality toy for long lasting and engaging play! One star docked for the sizing—I don't usually expect to need an xl anything for my 45lb border collie but he cant even fit his canine teeth into the large size to ease the jerky reward out in "hard" position but "easy" position he doesn't even tough the toy just grabs the jerky. Got an XL and it has been great for the jerky both easy and hard positioning. The larges I keep around for liquidy and frozen treats to keep the mess contained and they work very well for that.

Truly for Aggressive Chewers
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Excellent product for aggressive chewers. The black Kong doesn't last forever BUT it is the most reliable toy I've used with my 60# pitt mix. I've returned so many toys that were advertised as for this girl's level of enthusiasm that I no longer buy anything else.
