DBA Brakes for the Dodge Challenger: Which Parts Fit

By Core Brake Parts Tech Team — Circleville, OH warehouse

DBA makes front rotors for several versions of the Dodge Challenger's performance brakes, and the right one depends on which Brembo system your car left the factory with. A 2008-era SRT8 with the 360 mm front rotor takes the one-piece DBA Street Series XGold, while 2015 and later SRT and Hellcat cars with the 390 mm two-piece front rotor take DBA 5000 Series rings or complete two-piece rotors. Identify the brake package first, then pick the part.

Which Challenger Brake System Do You Have?

The Challenger has not used one brake package across its run, and DBA builds to each factory size. Dodge's own launch material lays out the two systems that matter here.

For 2008, Dodge stated that red Brembo calipers with four pistons sit at all four corners, with 360 x 32 mm front and 350 x 26 mm rear vented rotors. For 2015, Dodge said both Challenger SRT models got what it called the largest front brake package offered on an SRT vehicle up to that point: 390 mm two-piece Brembo front rotors with six-piston calipers.

Base, SXT, GT and R/T Challengers use smaller brakes, and the parts in this guide are not for them. If you are not sure what is on your car, look at the caliper and count the pistons on the inner face, then measure rotor diameter across the face. A four-piston caliper over a 360 mm rotor and a six-piston caliper over a 390 mm two-piece rotor are easy to tell apart once the wheel is off. Trim badges and wheels are not reliable indicators because owners swap them.

2008 to 2015 SRT8: DBA Street Series XGold

For the four-piston Brembo SRT8, the DBA Street Series XGold drilled and slotted front rotor (DBA2444X) is a one-piece direct replacement. DBA positions the Street Series as an OE-level performance upgrade, not a race part, which suits a car that is driven daily and taken on the occasional back road or autocross.

What you get over a plain replacement rotor, according to DBA:

• Kangaroo Paw ventilation. Instead of straight internal vanes, the Street Series uses DBA's Kangaroo Paw pillar pattern, which DBA says delivers up to 20 percent better heat dissipation.
• Cross-drilled and slotted face. The XGold pattern is non-directional, so left and right rotors are not handed. The drill holes and slots give pad dust and gases more exit points.
• Gold-finished hub. DBA is open that the XGold is a popular choice for show cars. If you only want the performance, its slotted T2 design is the plainer alternative.
• Corrosion protection. Non-friction areas are painted, and DBA also offers its EnShield zinc and aluminum coating on Street Series rotors.

Replace rotors in axle pairs, and pair them with fresh pads. You can browse compatible brake pads and new brake hardware kits for the abutment clips at the same time.

2015 and Later SRT and Hellcat: DBA 5000 Series

From 2015 the SRT Challengers moved to a 390 mm two-piece front rotor, and that changes how you buy replacements. A two-piece rotor is a cast iron friction ring bolted to a separate center section called the hat. When the ring wears out, the hat is often still fine.

DBA's 5000 Series is built exactly that way: high carbon cast iron rings joined to T6061-T6 aerospace-grade aluminum hats with National Aerospace Standards (NAS) bolts and crimp nuts. DBA sells hats and rings both as complete assemblies and as separate components, so drivers can reuse DBA 5000 Series hats and replace only the rings. DBA says the aluminum hats add further weight reduction and better heat management compared with its one-piece 4000 Series.

Ring only: DBA52910.1XS 5000 Series XS

The DBA 5000 Series XS front replacement brake ring (DBA52910.1XS) is a ring, not a full rotor. It is listed for the 2015 to 2017 Challenger and Charger SRT Hellcat six-piston front brake. Because it is a ring, you need a compatible hat to bolt it to. Before ordering, confirm your current front rotors really are two-piece and that the ring's listed fitment matches your hat. The XS pattern is DBA's cross-drilled and slotted design, which DBA says gives a performance benefit similar to its T3 slot.

Complete two-piece rotor: DBA53951.1S 5000 Series T3

For 2021 and later Challenger Hellcats, the DBA 5000 Series two-piece T3 slotted front rotor (DBA53951.1S) is listed as a complete two-piece rotor with M6 nuts. The T3 pattern is DBA's patented bi-directional slot design with tri-symmetrical slots, which DBA describes as giving a quieter, smoother braking experience. DBA recommends the T3 for high performance street cars, track days and club racing.

One more option on the same six-piston cars: the EBC Racing SG2 two-piece floating front rotors for the 2015 and later Challenger SRT Hellcat, if you want to compare a second two-piece design before you buy.

Signs Your Challenger's Front Rotors Need Replacing

SRT and Hellcat Challengers are heavy, fast cars, and the front rotors take most of the stopping load. The usual symptoms are:

• Pulsing pedal or steering shake under braking. Usually uneven pad deposits or thickness variation on the rotor face.
• A raised lip at the rotor's outer edge you can feel with a fingernail, or deep grooves.
• Heat cracks. Hairline cracks running out from drill holes, or cracks that reach the edge of the rotor, mean the rotor or ring is done.
• Blue or dark heat marks after hard use, often with a longer pedal while hot.
• Thickness at or under the minimum stamped on the rotor or ring. Measure with a micrometer at several points around the face and use the stamping on your part, not a number from a forum.

On a two-piece rotor, also check the hat-to-ring fasteners for looseness and the hat for cracks. A worn ring on a sound hat is a ring job. A damaged hat means a complete rotor.

What to Replace at the Same Time

• Front pads. Always. New rotors or rings with half-worn pads will not bed properly and can glaze.
• Caliper hardware. Abutment clips and pad pins wear and cause noise and uneven pad wear.
• Brake fluid. A hard-driven SRT is hard on old fluid. Flush with the fluid type listed on your master cylinder cap and in the owner's manual.
• Two-piece fasteners. When fitting DBA 5000 Series rings to hats, DBA specifies 13 Nm (9.6 ft lb) for the NAS nut and bolt assembly. For all other hardware, use the value in the factory service manual.

If a caliper is leaking or sticking, see our brake calipers; for braided lines, see brake lines.

How Hard Is the Job?

Swapping one-piece XGold rotors on an SRT8 is a standard front brake job for someone with a floor jack, stands, a torque wrench and basic hand tools: wheel off, caliper off and hung (never by the hose), bracket off if required to clear the rotor, rotor swap, reassemble, then bed in the new pads and rotors.

A complete two-piece rotor swap on a Hellcat is similar work, just with a heavier caliper. Replacing rings only adds a bench step: unbolting the old ring from the hat, cleaning the hat, fitting the new ring and torquing every NAS fastener to DBA's figure in a cross pattern. It is not difficult, but it is careful work, and a missed fastener matters at these speeds. Clean all new friction surfaces with brake cleaner before installation and follow a proper bed-in procedure before any hard driving.

Frequently Asked Questions

Will the DBA2444X fit my Challenger R/T?

It is built for the SRT8 with the 360 mm Brembo four-piston front brake. R/T and V6 Challengers use smaller brakes, so check your caliper and rotor diameter before ordering.

Can I put 5000 Series rings on my factory two-piece hats?

DBA designs its replacement rings to reuse DBA 5000 Series hats. Some DBA rings are also listed for specific factory two-piece setups, so match the part's listed fitment to your car and confirm your hat before ordering.

Is drilled and slotted better than slotted only for track use?

DBA says its drilled and slotted patterns give a benefit similar to its slotted designs, and it recommends the T3 slotted design for high performance use. For regular track days, many owners choose slotted only.

Do I need to replace rotors in pairs?

Yes. Replace both front rotors or both rings together so braking stays even side to side.

Does my 2015 Challenger SRT 392 have the same front brakes as the Hellcat?

Dodge's 2015 press kit says the 390 mm Brembo two-piece front rotors with six-piston calipers were standard on both Challenger SRT models that year. Later model years and trims changed, so verify on your own car.
