- Higher price than basic ceramic pads but offers better towing/hauling value through improved stopping and thermal stability.
Product Overview and Key Specifications
The Power Stop Z36-2225 Rear Z36 Truck carbon-fiber ceramic brake pads offer a direct, performance-focused upgrade for 2019–2025 Ram 2500 and 2019–2025 Ram 3500 models that use the 8x165mm rotor bolt pattern.
Power Stop Z36-2225 rear carbon-fiber ceramic pads: direct performance upgrade for 2019–2025 Ram 2500/3500 with 8x165mm rotors
This overview lists key specifications, materials, and practical notes.
What is the brake pad composition? Carbon-fiber ceramic, noted for severe-duty stopping power and reduced dust.
How is thermal performance addressed? Thermal-scorched surfaces speed break-in and improve fade resistance.
Specifications: weight 6.6 lb, dimensions 10.2 x 6.1 x 2.6 in, part Z36-2225.
Includes stainless steel shims, hardware kit, and grease for installation.
Performance and Real-World Driving Impressions
Following the specification and fitment details, this section examines how the Z36-2225 pads perform in real-world use, with measured observations and practical notes for daily driving, towing, and off-road work.
The reviewer notes consistent braking performance: 60–0 mph stops shortened by ~5–7 ft versus stock, firm pedal feel, minimal fade after repeated stops.
User feedback cites low dust, quiet operation, and reliable modulation under load.
Q: How do they handle towing?
A: Stable temperature control, acceptable at gross combined weights up to typical light-truck loads.
Consider initial 150–200 mile break-in and periodic pad inspections for heavy use.
Installation Experience and Included Hardware
Although a seasoned mechanic can complete the rear pad swap in under an hour per axle, a competent DIYer should plan for 60–90 minutes the first time, depending on tools and rust conditions.
The kit includes stainless steel hardware, premium shims, and a small tube of brake grease; hardware quality is clearly above average, fitting 8x165mm rotor bolt patterns without modification.
Installation tips: clean caliper slider pins, measure pad thickness before and after, torque caliper bolts to spec (usually 85–105 ft·lb depending on model).
Question: any special tools?
Answer: common hand tools, C-clamp or caliper piston tool, torque wrench.
Compatibility, Fitment, and Use Cases
Having finished the mechanical notes on installation time and hardware, attention now shifts to which trucks these Power Stop Z36-2225 pads will actually fit and what owners can expect in real-world use.
These rear pads fit 2019–2025 Ram 2500 and 2500/3500 models with the 8x165mm rotor bolt pattern; measurements: 10.2 x 6.1 x 2.6 inches, 6.6 lb package.
These rear pads fit 2019–2025 Ram 2500/3500 trucks with the 8x165mm rotor bolt pattern, 10.2×6.1×2.6 in.
Q: Any fitment issues?
A: Few reported, confirm 8x165mm pattern and single/dual rear wheel setup before purchase.
Use cases: towing, hauling, off-road; expect towing benefits—improved stopping power, reduced brake dust, and thermal stability under load.
Pros, Cons, and Value Assessment
Value assessment centers on measurable trade-offs: the Z36-2225 pads deliver stronger stopping power and improved thermal stability compared with standard ceramic pads, reduced dust generation, and a package weight of 6.6 lb with pad dimensions of 10.2 x 6.1 x 2.6 inches that fit 8x165mm rotor bolt patterns on 2019–2025 Ram 2500/3500 models (single and dual rear wheels).
Pros: improved braking performance, carbon-fiber ceramic, thermal scorched surface, included hardware, dust reduction.
Cons: higher cost than basic ceramics, potential uneven wear under extreme use.
Is it worth it? For towing/hauling, yes. Consider mileage and driving style.
Frequently Asked Questions
Do These Pads Require Any Bedding-In Procedure Beyond Thermal Scorch?
Like a knight with a smartphone, he notes no extensive bedding in process beyond the thermal scorch; routine light stops for initial thermal performance suffice, followed by normal use, ensuring ideal friction transfer and consistent braking behavior.
Are They Compatible With Coated or Aftermarket Rotors?
Yes. The reply states compatibility concerns are minimal: the pads work with various rotor types, including coated or aftermarket rotors, though matching surface finish and proper bedding guarantees peak performance and reduced wear or noise.
How Do They Perform in Sustained Downhill Braking/Towing?
Like a steady drumbeat, they maintain consistent friction under prolonged loads; their carbon-fiber ceramic design delivers sustained performance and improved downhill safety for towing, resisting fade and reducing dust while providing reliable, quieter braking confidence.
Do They Affect ABS or Traction Control System Behavior?
They typically do not alter ABS interaction or traction control, as they maintain similar friction characteristics to OEM pads; however, slight modulation differences during aggressive or sustained braking may be noticed, depending on vehicle calibration and bedding-in.
Are There Any Recommended Brake Fluids to Use With Them?
109 reviewers note improved feel; he recommends DOT 3, DOT 4, or DOT 5.1 for brake fluid types, checking fluid compatibility with vehicle manufacturer. Synthetic DOT 5 (silicone) is generally avoided for compatibility.
