EBC S9KR1643 Yellowstuff + USR Slotted Rear Brake Kit 2019-2023 Silverado 1500

Vehicle Fitment

• 2019-2023 Chevrolet Silverado 1500 (rear axle, compatible trims with 6-lug rear setup)
• 2021-2023 Chevrolet Tahoe (rear axle, compatible 6-lug rear hub variants)
• 2021-2023 GMC Yukon / Sierra 1500 (rear axle, 6-lug rear hub / matching rotor spec)

Features

• High-friction "Yellowstuff" rear brake pads - strong initial bite and enhanced stopping power over stock pads
• USR fine-slotted, vented rear rotors - slots evacuate brake gases, water, dust and debris to maintain consistent pad-to-rotor contact under load
• Vented, 1-piece rear rotors designed for heavier-load trucks/SUVs - improved heat dissipation and fade resistance under towing, heavy cargo or repeated braking
• Thermic / anti-corrosion coating on rotor surfaces for better rust protection and long-term durability in varied climates
• Direct-fit kit - engineered for bolt-on replacement on compatible rear hubs / brake caliper assemblies (no modifications needed when specs match)
• Kit includes both rear wheels' rotors and pads - convenient full-axle refresh or upgrade in one purchase
• Balanced compromise between performance and longevity - suitable for daily driving, towing/heavy load, and occasional spirited or heavy braking demands
• Improved brake control and pedal feel under load compared to stock rear brake components

Specifications

• Position: Rear axle (2-wheel set)
• Pad compound: Yellowstuff high-friction para-aramid composite

Product Description

The EBC S9KR1643 rear brake kit is designed as a robust, bolt-on upgrade for late-model full-size trucks and SUVs (e.g., 2019-2023 Silverado 1500, Tahoe, Yukon) that use compatible 6-lug rear hubs. By combining the high-friction "Yellowstuff" pads with USR vented, slotted rotors, this kit significantly improves braking performance under load - offering stronger initial bite, better heat management, and more consistent pad-to-rotor contact under repeated or heavy braking. Such characteristics make it an excellent choice for towing, hauling, heavy use, or spirited driving when stock brakes struggle.

The vented rotors and anti-corrosion coating help maintain rotor health and longevity even under harsh conditions or frequent exposure to road salt and moisture. Because the kit matches factory bolt-pattern and brake-system geometry for listed vehicles, installation is straightforward, requiring no custom modifications. Sold as a complete rear-axle kit (rotors + pads), S9KR1643 provides a full rear-brake refresh in one go - ideal for owners looking to upgrade braking bite, reduce fade, and improve pedal feel while maintaining reliability and durability.

**Important:** Before ordering or installing - confirm that your vehicle's rear hub uses a compatible 6-lug bolt pattern, matching calipers (FMSI pad spec D2174), and that rotor diameter/spacer specs match the kit. Always check rotor run-out after installation, torque hardware to manufacturer spec, and perform a proper pad bedding-in procedure to ensure optimal performance and longevity.
