When we talk about the best Wilwood big brake kit for Ram trucks, these specifications are exactly what set this kit apart from generic or partial upgrades. The inclusion of both front and rear systems, combined with the high-performance fluid and lines, makes this a true all-in-one solution.

Opening the box from Accesspeed reveals a thoughtfully organized kit. You get two individual TX6R big brake kits (front and rear), each containing the six-piston calipers in red, the 16-inch slotted rotors, and all necessary mounting brackets and hardware. The stainless steel braided Flexlines are included separately, packaged carefully to avoid kinks. Two bottles of Wilwood 570 Racing Brake Fluid complete the package. The packaging is functional and protective, with foam inserts holding the heavy rotors securely. First impressions of the build quality are excellent; the calipers feel solid and the rotors have a precision-machined finish. Everything appears high-end, which is expected for a kit in this price range. It is a complete drop-in package for the Ram 2500 big brake upgrade worth it discussion, as nothing else needs to be sourced unless your wheels require spacers.

Before you begin any mechanical work, you must verify wheel clearance. According to the manufacturer, this kit requires 20-inch or larger wheels, and wheel spacers may be necessary. Measure your wheel’s inner diameter and spoke clearance against the provided template. If there is any interference, you will need high-quality spacers. Jack up the truck securely and remove the wheels.
Start by removing the factory brake calipers and rotors. Disconnect the brake lines carefully to avoid spilling too much fluid. Set the OEM parts aside. Clean the wheel hub surface thoroughly with a wire brush to ensure the new rotors sit flat. This step is crucial for preventing brake judder.
Install the front Wilwood caliper brackets using the supplied hardware and torque them to the manufacturer’s specifications. Slide the 16-inch GT-60 rotor onto the hub. Attach the TX6R six-piston calipers to the bracket. Use the included Wilwood stainless steel braided Flexlines to connect the caliper to the truck’s hard line. Ensure the lines are routed without kinks and are secured away from moving suspension parts. Repeat for the other side.
Note that the rear kit replaces the factory disc brakes but uses the OE parking brake assembly. If your 2014-2018 Ram 2500 or 3500 has an OEM electronic parking brake, this kit is not compatible. For trucks with a manual parking brake, the installation process mirrors the front: install brackets, mount the rotor, attach the TX6R caliper, and connect the brake line. This is a common point of confusion when researching the should I buy Wilwood big brake kit Ram question.
This kit includes Wilwood 570 Racing Brake Fluid, which has a high dry boiling point. Use a power bleeder or the two-person method to bleed the entire system. Start with the farthest wheel from the master cylinder (usually the rear passenger side) and work your way forward. Bleed until all air bubbles are gone and the pedal feels firm. The stainless steel lines reduce expansion, but the fluid must be air-free for optimal performance.
Bedding-in is critical for the new pads and rotors to develop a proper transfer layer. Find a safe, empty road. Accelerate to about 40 mph, then brake firmly to 10 mph without coming to a full stop. Repeat this process 8-10 times. Allow the brakes to cool by driving for a few minutes without using them. Avoid hard stops during the first 100 miles. This process ensures you get the full benefit of the best Wilwood big brake kit for Ram investment.
After bedding-in, inspect all bolts for tightness and check for any fluid leaks. Monitor pad wear and rotor condition every few thousand miles, especially if you tow frequently. The Spec-37 alloy rotors are durable, but the pads may wear faster than OEM under severe use. Routine maintenance involves checking fluid levels and inspecting the braided lines for damage.

We tested this Wilwood kit on a 2016 Ram 3500 dually over a period of three weeks. The truck was used in its natural environment: towing a 12,000-pound trailer through mountain passes and around city traffic. We measured stopping distances from 60 mph with the trailer attached and recorded brake temperatures using an infrared thermometer after repeated hard stops.
The initial improvement over OEM brakes was dramatic. With the factory system, stopping from 60 mph with a heavy trailer felt concerning, often requiring significant pedal pressure and resulting in noticeable fade after two or three stops. With the Wilwood TX6R kit, pedal feel was firm and linear. Stopping distances decreased by an estimated 15-20 percent based on our measured markers. The six-piston calipers provide immense clamping force without requiring extra pedal effort. This is a clear example of why the Wilwood TX6R brake kit pros cons list leans heavily positive for towing applications.
During a descent on a 6-percent grade, we made three hard stops from 55 mph to 15 mph to simulate emergency braking. The OEM brakes had begun to fade by the third stop, with a soft pedal and increasing stopping distance. The Wilwood kit performed all three stops with consistent pedal feel and no detectable fade. Rotor temperatures peaked at around 550 degrees Fahrenheit, well within the operating range for the Spec-37 alloy and pads. After extensive use, we found no signs of cracking, warping, or uneven pad wear.
Wilwood claims these kits deliver consistent stopping power and extreme duty durability under sustained high heat. Based on our testing, that claim holds up. The only caveat is that the kit requires proper bedding-in to achieve this performance. Without the bedding-in procedure, the pads may not transfer material correctly, leading to reduced bite. For anyone asking Ram 2500 big brake upgrade worth it, our real-world results confirm that the investment pays off in safety and confidence.

Choose the Wilwood TX6R kit if you tow heavy loads regularly, drive through mountainous terrain, or want the ultimate in braking confidence. It is also the right choice for those who demand the best brake upgrade for Ram 3500 vehicles that are used for commercial or serious recreational towing.
If your Ram is a daily driver that rarely tows over 8,000 pounds, the PowerStop Z36 or even a high-quality OEM replacement rotor and pad setup may be sufficient. The Wilwood kit is overkill for light-duty use and its high cost may not deliver noticeable benefits in that scenario.
Measure your wheel’s inner diameter and spoke clearance against the provided template. You may need spacers, which add cost and complexity. Doing this upfront saves disappointment.
Bleeding the brakes without a power bleeder is tedious with such a large system. A pressure bleeder ensures you get all the air out, which is critical for pedal feel.
The stopping power of this kit can exceed the grip of budget tires. For maximum value, ensure your tires are capable of handling the increased braking force.
Do not skip the 10-12 moderate stops followed by a cool-down period. A proper bed-in ensures even pad transfer, which prevents noise and maximizes rotor life.
The Wilwood 570 Racing Brake Fluid has a high boiling point. Do not substitute with standard DOT 3 fluid, as it will boil under hard use and reduce performance.
Stainless steel lines are durable but can chafe against suspension components if not routed correctly. Check them after the first few drives and periodically thereafter.
A master cylinder brace for your Ram 2500 can reduce firewall flex and improve pedal firmness further, maximizing the benefit of this big brake upgrade.
The current price for this complete Wilwood front and rear big brake kit is $6,169.00. When you factor in the cost of the individual front and rear kits, plus the stainless lines and high-performance fluid, this package price is competitive. Compared to buying OEM replacement rotors and pads, the Wilwood kit is significantly more expensive. However, for those who need the performance, it offers a unique value proposition. Potential buyers should check for seasonal deals or bundle offers from Accesspeed.

Based on our testing, yes, for the right user. The investment of over $6,000 is justified if you regularly tow over 10,000 pounds or demand maximum braking performance. The reduction in stopping distances and elimination of brake fade under heavy use are tangible safety benefits. For light-duty drivers, the cost may outweigh the benefits.
The stock system on the Ram 2500 and 3500 is adequate for daily driving but struggles under heavy loads, particularly when descending grades. The Wilwood kit offers vastly superior heat dissipation, a firmer pedal, and shorter stopping distances. It also weighs more but provides significantly better durability. This is the core of the Wilwood vs OEM Ram brakes debate, and the Wilwood kit wins for heavy-duty use.
If you are comfortable with basic brake work, such as replacing rotors and pads, you can tackle this installation. The process is straightforward but requires attention to detail, especially when routing the brake lines. Bleeding the system is the most challenging part for beginners. Plan for a full day of work.
You will need basic hand tools, a jack and jack stands, and a brake bleeder (preferably a power bleeder). If your wheels do not clear the 16-inch rotors, you will need wheel spacers. It is also wise to have a torque wrench to ensure all bolts are tightened to spec. No additional parts are required for the brake system itself.
Wilwood works directly with the buyer for warranty issues. Accesspeed, the seller, handles initial inquiries but does not accept returns on installed items. It is crucial to verify fitment before installation. Customer support is professional but limited by the return policy.
We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon often has the best availability and fast shipping. You can also check Wilwood’s official website for a list of authorized dealers, but the Accesspeed package with the free brake lines and fluid is an excellent value.
Most factory 20-inch wheels will not clear the 16-inch rotors without wheel spacers. You must consult the wheel clearance diagram provided by the manufacturer. Measure your specific wheel’s inner diameter and spoke profile before ordering. This is a common point of confusion when researching best brake upgrade for Ram 3500 applications.
Pad life depends on usage, but with regular towing, expect pad replacement every 20,000 to 30,000 miles. Rotors are more durable; the Spec-37 alloy can last through two or three pad sets if not abused. Frequent hard stops will accelerate wear. Regular inspection is recommended.
