2015–2020 Toyota Land Cruiser J70 Series | PN 140-17347
Modern Big Brake Performance for the Legendary LC70
The Wilwood 140-17347 FNSL6R/EPB Big Brake Rear Kit delivers modern stopping power to the rugged and iconic Toyota Land Cruiser 70 Series (LC70). Designed for vehicles sold in Japan, South America, Africa, and the Middle East, this complete rear brake system combines high-capacity six-piston calipers, large two-piece GT slotted rotors, and Wilwood’s integrated Electronic Parking Brake (EPB) solution for superior braking performance and durability.
Engineered to work with the OEM master cylinder output and ABS system, this kit provides effortless braking improvement for stock, enhanced, and even up-armored vehicles.
6-Piston FNSL6R Calipers with EPB Integration
This kit features Wilwood’s Type III anodized FNSL6R six-piston calipers, delivering increased clamping force and improved brake modulation over factory components. Stainless steel pistons (1.75", 1.25", 1.25" bore configuration) provide a total piston area of 4.86 in² for strong, consistent braking under heavy load conditions.
Integrated into the system is Wilwood’s latest Electronic Parking Brake (EPB) caliper, maintaining modern functionality while upgrading braking performance—ideal for daily-driven, expedition, and heavy-duty Land Cruisers.
12.88" GT Slotted Rotors for Heat Management
The kit includes 12.88-inch diameter, 1.25-inch thick two-piece GT slotted rotors with 42 internal vanes for enhanced cooling and thermal efficiency. The slotted surface design improves pad bite, evacuates gases and debris, and enhances overall braking consistency.
Constructed from iron with a black electro-coat finish, these dynamically balanced rotors provide strength, durability, and corrosion resistance in harsh environments.
BP-20 SmartPads for Balanced Street & Heavy-Duty Use
Wilwood’s BP-20 SmartPads offer a balanced friction compound ideal for trucks and SUVs. Designed for consistent stopping power with predictable pedal feel, they perform well in both daily driving and heavier-duty applications.
