What is an axle pack?

This brake kit comprises specifically designed and pre-matched brake pads and rotors that are performance-focused.

What are three reasons to upgrade to such a kit?

More Consistent Braking Power:

You are unlikely to encounter any problems with them during leisurely driving. But, when you start to engage in spirited or aggressive driving, you will see their shortfalls. The reason is that they get overwhelmed when heat builds up at the wheels, such as during spirited driving or aggressive braking. You can count on the StopTech drilled rear axle pack 939.51521 to deliver more reliable braking power because it has higher heat tolerance. It features high-quality brake pads that are made from superior, heat-resistant materials. It also features vented heavy-duty rotors with an OE vane design that goes a long way in helping to eliminate heat.

Shorter Braking Distances:

This brake kit’s brake pads have unique friction formulations that achieve a more substantial bite, and as a result, you are always assured of shorter braking distances with this brake kit. The more robust materials of the premium rotors also help to slow the car down quicker. Shorter braking distances make for more exciting driving experiences and enhanced performance.

Greater Longevity:

With this kit, you will go for longer without having to do any brake part replacements. This brake kit’s premium rotors have an electro-statically applied finish. They can withstand up to 400 hours of exposure to saltwater without rusting, thanks to this finish. Also worth noting is that this kit’s brake pads and rotors both utilize wear-resistant materials that resist cracking in high friction or high heat situations.

Why buy the StopTech drilled rear axle pack 939.51521?

• Brake pads and rotors can’t be paired together randomly because they are designed for other purposes and in various grades. Brake part manufacturers develop brake kits for different purposes, using other materials. When brake pad/rotor upgrades are mismatched, they may fail to deliver the desired improvements in braking performance. The pre-matched StopTech axle pack covers the brake pad and rotor matching part for you, so you can go right ahead and install it. Its components have been carefully pre-matched for you.


• The StopTech drilled rear axle pack 939.51521 brake kit is produced in the USA, so you are assured of high-quality standards in the pads and rotors' production processes.


• This kit costs just $228.45, which is quite affordable.


• It is designed to produce the lowest amounts of dust and noise.
