J.C. Whitney JSTPD27110049DRS Rear Cross-Drilled & Slotted Brake Disc OEM Replacement

The J.C. Whitney JSTPD27110049DRS is a rear, cross-drilled and slotted brake disc designed as a direct OEM replacement for select Ram 2500 and Ram 3500 pickup trucks. Sold individually, this rotor fits both the driver and passenger side (RH=LH), simplifying parts ordering and inventory.

The cross-drilled and slotted disc design delivers a meaningful upgrade over standard smooth rotors. Cross-drilled holes promote airflow across the rotor face, dissipating heat more efficiently during heavy or repeated braking. The machined slots evacuate water, dust, and gases from the pad-to-rotor contact surface, maintaining consistent bite and reducing brake fade under demanding conditions.

Key Features:

• Cross-Drilled & Slotted Design – Improves cooling, reduces fade, and expels debris from the braking surface
• OEM Replacement Fit – Engineered to match factory dimensions for a direct, bolt-on installation with no modifications required
• Interchangeable Left/Right – Single rotor fits both driver and passenger rear positions (RH=LH)
• Vented Construction – Internal vane design further enhances heat dissipation for heavy-duty truck applications
• Sold Individually – One brake disc per order
• Part Number: JSTPD27110049DRS

This rotor is built to handle the demands of heavy-duty truck operation, providing reliable stopping performance as a drop-in replacement for worn or damaged factory rear brake discs.
