The Story
Brake Kit for Heavy-Duty GM Front Applications
The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a front disc brake service solution for select Chevrolet and GMC trucks, vans, and Suburban models from 1978-1993. Part number 4502-48038 combines coated rotors and matched pads for OE-style service on demanding front axle applications.
Key Features
- Complete front disc brake kit with rotors and pads
- DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
- Rotors ship dry and are ready to install without oil removal
- G3000/G11H18 cast iron rotor construction for OE-spec durability and stability
- Non-directional rotor finish for more even pad bed-in and quieter stops
- 100% inspected rotors with balance correction on vented units
- DFC 5000 Advanced pads are post-cured and scorched for stable friction performance
- Premium rubber-steel-rubber shims for improved NVH control
- 12-month warranty against defects in material and workmanship on rotors
Product Line Details
DFC GEOSPEC rotors are built for corrosion resistance and installation efficiency, with a dry finish that eliminates the need to clean protective oil before assembly. The 5000 Advanced Brake Pads are formulated for consistent friction across a wide range of vehicle applications, including family-duty and light commercial use, and are assembled with premium shims to help reduce noise, vibration, and harshness.
Detailed Description
Part number 4502-48038 is engineered for front brake service on a broad range of Chevrolet and GMC platforms, including C20, C20 Suburban, C2500, C2500 Suburban, G30, G3500, P20, P30, P2500, P3500, R20, R2500, and R2500 Suburban applications. The coated rotors are machined to tight tolerances, finished non-directionally, and inspected to OE specifications for fit, balance, and consistency. The included pads are post-cured and scorched to reduce initial break-in time and deliver stable stopping performance from the first stop.
This kit is a practical choice for front brake refreshes on Chevrolet P30 front brake service, GMC P3500 front axle repairs, and Chevrolet G30 front disc brake replacement where corrosion protection and predictable pedal feel matter. Part number 4502-48038 is built to streamline service while maintaining OE-style fitment and finish.
What This Kit Helps Address
- Front brake noise, vibration, or harshness during stops
- Rust buildup on exposed rotor surfaces
- Uneven pad bed-in after brake service
- Reduced stopping consistency from worn rotors and pads
- Time lost cleaning oil-coated replacement rotors before installation
