Baer Sport Baer Brakes 12 Inch Rear SS4 Brake System with Park Brake Red for 07-25 Wrangler JK
$1094.95
Free Shipping

If you're looking to upgrade your Jeep's braking system, the Baer SS4 rear brake setup is worth a serious look. This kit features a robust 4-piston S4 caliper paired with a solid 12.2-inch one-piece rotor that's been thoughtfully designed with slots and a zinc plating for added durability. You won’t have to worry about dirt and grime getting in there either, thanks to the D.O.T. compliant dust and weather seals that keep everything running smoothly.

Fitment:

  • Perfectly designed for 2007-2017 stock Jeep JK rear setups.

Why the SS4 is a Smart Choice:

  • Those 12.2-inch rotors are directionally vaned, which helps with heat dissipation—great for those long off-road trails or spirited drives.
  • Pair it up with the Track4 front brake system for a complete package that looks and performs great.
  • Uses the same brake shoe as the late model Corvette C5/C6, so you know it’s got some pedigree.
  • Comes with all the fittings and hardware you need to get it installed without a hitch.
  • These rotors fit some 15-inch and most 16-inch wheels, but double-check with a template to be sure.

What Makes the S4 Caliper Stand Out:

  • Stiffness is key—this caliper has four 10mm cross bolts to keep everything tight and responsive.
  • Stainless steel abutments and noise suppression springs help keep things quiet, even under heavy braking.
  • With hard anodized aluminum pistons, you get a lightweight yet durable component.
  • The internal crossover design and dual seals meet D.O.T. specs, ensuring reliability in all conditions.
  • Each caliper is finished with a machined logo that’s hand-painted—details matter, right?
  • It uses a common 4-piston pad (P/N DR1), making replacements a breeze.
  • Choose from a standard red, black, or silver powder coat finish, or go for a custom color if you want to stand out.
  • Available for both front and rear, so you can keep that aesthetic consistent across your Jeep.
  • For C-clip style axles, you’ll get Baer’s Verislide self-centering brackets—no more worries about alignment.
  • Uses correct banjo-style fittings—no pipe threads here; just solid engineering.
  • And yes, it's 100% made in the USA with materials sourced right here.

Product Fitment:

  • Jeep Gladiator 2020-2025
  • Jeep Wrangler 2007-2025

So if you're serious about your Jeep's braking performance, the Baer SS4 system is a solid upgrade that won’t let you down.
