Wilwood 150-TX1-6617K TX1 Off-Road Brake Pad Set for W6A W4A AERO4/6 Calipers

Vehicle Fitment

• Universal - for use with Wilwood W4A, W6A, Aero4, Aero4-DS, Aero6, Aero6-DS, and AeroDM caliper families (Pad #6617 plate)

Fitment Notes

• Confirm your specific caliper uses the 6617 pad plate before ordering - Wilwood's W4A/W6A/Aero4/Aero6 caliper family covers a range of piston counts and rotor diameters, but not all variants use this exact pad
• Compatible with iron and steel rotors
• TX1 is a specialty compound intended primarily for off-road and armored vehicle applications rather than standard street or road-race use - for street/track driving, Wilwood's BP-Q, BP-10, BP-20, or BP-28 compounds in this same pad plate are typically more appropriate

Features

• Medium-high friction pad with flat torque output across a wide temperature range, from 100°F to 1200°F
• Smooth, predictable pedal feel for confident modulation
• Medium-low pad wear rate
• High-performance compound purpose-built for armored vehicle braking demands
• Compatible with iron and steel rotors within their intended temperature ranges

Product Description

The Wilwood 150-TX1-6617K is a brake pad set in Wilwood's specialty TX1 compound, built for the demanding braking requirements of armored and off-road vehicles. It uses the 6617 pad plate, making it compatible with Wilwood's W4A, W6A, Aero4, and Aero6 caliper families across their various piston configurations and rotor diameter ranges.

TX1 delivers medium-high friction with notably flat torque output across an unusually wide temperature range - from 100°F all the way to 1200°F - giving consistent, predictable stopping power whether the vehicle is cold or has been under sustained hard braking. Pedal feel is smooth and predictable, and the compound carries a medium-low wear rate, both important traits for heavy-duty vehicles that need reliable braking without frequent pad changes.

As a specialty compound, TX1 is intended primarily for off-road and armored vehicle use rather than typical street or road-race driving - Wilwood offers other compounds (BP-Q, BP-10, BP-20, BP-28) in this same 6617 pad plate for those applications. This pad set is compatible with iron and steel rotors within their intended temperature ranges.
