If you're looking to boost your Jeep's braking performance, this Baer Brakes 12" SS4 Rear Brake Kit is a solid choice. Designed to fit 2007-2025 Jeep Wrangler JK, JL, and 2020-2025 Gladiator JT models with the stock rear end, this kit is all about bringing reliable stopping power to your off-road adventures.
At the heart of this system is the S4 4-piston caliper, which is mounted to a robust 12.4" rotor. This isn’t just any rotor; it’s a one-piece, slotted and drilled design that’s zinc plated for durability. You’ll appreciate the way it handles heat and reduces brake fade, especially if you’re pushing your Jeep to its limits on the trails.
One of the standout features here is the caliper itself. Manufactured in Phoenix, AZ, it’s made from CNC machined forged or billet aluminum, giving it a lightweight yet incredibly strong build. Plus, the hard anodized aluminum pistons and stainless steel abutments ensure it stands up to the elements. With dual dust and weather seals, you won’t have to worry about dirt and grime ruining your ride.
Now, if you’re wondering about fitment, this kit is designed to work seamlessly with your Jeep’s OE rear end. Just keep in mind that it doesn’t come with brake hoses, so you’ll need to reuse your stock ones. It’s a straightforward install that won’t require any fancy tools or tricks, making it a decent weekend project for any DIY enthusiast.
So, if you’re ready to take your Jeep’s braking game to the next level, this Baer Brake kit is worth considering. It’s all about giving you the confidence to tackle whatever the road—or trail—throws your way.
