A Direct Compound Upgrade for the Ram HD Rear Axle
DBA DB2703XP is the Xtreme Performance version of the 194.5 mm rear pad used by the 2019-2024 Ram 2500 and 3500 (DJ) 6.7L 4WD. The footprint is identical to the Street Performance pad at 194.5 by 57.3 by 19.1 mm, so this is purely a compound step up: low-copper carbon-fibre semi-metallic with higher initial bite for towing and severe duty.
Key Features
- XP compound with high initial bite, aimed at heavy towing and severe-duty braking.
- Semi-metallic carbon-fibre friction material with low copper content.
- Slotted friction face plus shims for noise control.
- TSP scorched surface treatment for a shorter bed-in.
- Identical 194.5 mm by 57.3 mm by 19.1 mm footprint to the SP version, so it is a straight compound upgrade with no fitment change.
- Packaged at 2.94 kg in a carton measuring 5.00 by 4.00 by 9.30 in.
- Supersedes the earlier DB2703 part number.
Fitment
| Vehicle | Axle and restrictions |
|---|---|
| Ram 2500 (DJ) | 2019-2024, 6.7L, 4WD, rear axle |
| Ram 3500 (DJ) | 2019-2024, 6.7L, 4WD, rear axle |
Two-wheel-drive Ram HD coverage is not published on any fetched source, so DBA DB2703XP carries only the confirmed 4WD tags.

About DBA
DBA runs SP and XP as two compounds on the same pad backing plates wherever the application allows, which lets an owner change braking character without changing hardware. XP is the higher-bite, higher-temperature option intended for towing and severe duty. DBA DB2703XP is that compound on the Ram HD rear shape.
FAQ
What is in the box and which wheels does it cover?Four pads, which is the full rear axle for one truck. The fronts on the same Ram HD chassis use a different DBA part number.
Is it interchangeable with the SP version?Yes, physically. Both use the same 194.5 by 57.3 by 19.1 mm pad, so swapping between them is a compound change only.
Why choose XP over SP on a truck?XP is formulated for higher initial bite and heavier duty, which suits regular towing or loaded work.
Is it chamfered?No. Unlike the SP pad, the XP version of this shape is slotted and shimmed but not chamfered.
Is the compound copper free?No. XP is a low-copper formulation rather than a copper-free one.
What does the box weigh?2.94 kg packaged for the four pads.
Can I mix an XP rear with an SP front?DBA does not publish a mixed-compound recommendation, so matching compounds front and rear keeps the brake balance predictable.
Does it need bedding in?Yes, the standard DBA bed-in still applies, though the scorched face shortens it.
What is the warranty term?12 months or 20,000 km / 12,000 miles.
Installation Instructions
- Have the pads fitted by a qualified technician in line with DBA's friction guidance.
- Chock the front wheels, support the rear axle on rated stands and remove both rear wheels.
- Compare the outgoing pads against the new set: the XP and SP versions share this shape, so confirm the compound marking before assuming a like-for-like swap.
- Inspect the rotors for heat checking and measure thickness against the minimum specification.
- Clean the carrier abutments, retract the pistons, and fit the four pads with their shims.
- Refit the caliper, pump the pedal until firm, and confirm the wheels turn without drag.
- Bed in on a clear road: from 50 km/h (30 mph) brake down to 10 km/h (5 mph) with medium pedal pressure without coming to a stop.
- Repeat that cycle about ten times with roughly 30 seconds of rolling cool-down between each one.
- Avoid heavy or prolonged braking for the first 200 km (120 miles) so the friction transfer layer stabilises.
