This item ships for free! (Continental U.S. only)

The TeraFlex Delta Brake System is the ultimate upgrade for JL and JK Wrangler/Unlimited and JT Gladiator models with oversized and heavier wheels/tire combos requiring increased braking performance. A must for 33-42” tires or heavy-laden overland rigs. Includes all the components required to upgrade both front and rear axles. 

Delta Brake Calipers feature a high-modulus bridge. Modulus measures a material’s resistance to elastic (recoverable) deformation under load. A stiff material has a high modulus, which means it only changes shape slightly under high elastic loads before returning to its normal shape. 

Fits:

• JL Wrangler (2-door) 
• JL Wrangler Unlimited (4-door) 
• JK Wrangler (2-door) 
• JT Gladiator (pickup) 
• JK Wrangler Unlimited (4-door)

• Minimum Wheel Diameter: 17” 
• Back Spacing: 4.75” or less 
• MUST VERIFY FITMENT W/ DOWNLOADABLE TEMPLATE 
• Bolt Pattern: 8x6.5” 

Includes:

• High-Modulus Brake Caliper Kit w/ Pads – Front (# 4403401) 
• High-Modulus Brake Caliper Kit w/ Pads – Rear (# 4403402) 
• 14” X 1.25” Vented & Slotted Rotors w/ 8x6.5” – Front (# 4403485) 
• 14” X 1.25” Vented & Slotted Rotors w/ 8x6.5” – Rear (# 4403486) 
• All necessary hardware 

Features & Benefits:

Delta Brake System:

• Significantly improved braking performance over factory brake system 
• 100% bolt-on upgrade w/ basic hand tools 
• Balanced front to rear brakes tuned specifically for lifted vehicles 
• Brake bias and piston sizes optimized for JL and JK Wrangler/Unlimited and JT Gladiator models 
• Designed to work w/ stock proportioning valve and ABS 
• 3-year warranty

High-Modulus Brake Calipers:

• Opposed 4-piston caliper design w/ 2” front pistons and 1.375” rear pistons 
• Same flow rate as factory 2-piston calipers – 4 pistons move each side half the distance instead of 2 pistons only moving one side the full distance 
• EPDM synthetic boot material keeps water and other contaminants away from piston 
• Hard-chrome coating on piston reduces friction to improve performance 
• 4-piece High-Modulus bridge caliper design combines heat-treated 4140 cast steel bridges w/ 6061-T6 forged aluminum piston housings 
• Steel bridges resist bending/flex better than standard aluminum or cast iron
• Improved stiffness = consistent brake feel/modulation during brake application and release 
• Low-profile bridge accepts 14” diameter rotors behind 17” wheels 
• 1,000-hour salt spray tested zinc- and E-dipped coating on bridges and mounts 
• 300,000 psi steel formed hardware 
• Calipers feature built-in auto bleeding check ball, valve, and spring for easy bleeding 
• Hard-coat anodized, scratch-resistant piston bores

Brake Rotors:

• Massive 14” x 1.25” vented rotors for superior stopping performance 
• Larger diameter rotors offer more mechanical advantage for more stopping power 
• Heat-treated, heavy cast-iron rotors offer better heat absorption 
• Mill-balanced, vented rotors for maximum heat dissipation 
• Included slotted rotors offer better gas dissipation than smooth rotors 
• GEOMET coating on non-friction surfaces resists corrosion

Brake Pads:

• Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub w/ increased pad life and reduced noise and dust 
• Drop-in pad design – no need to disassemble calipers to replace pads

Stock Brake Rotor Reference:

• JL Sahara/Rubicon front: 12.9” x 1.1” (330mm x 28mm) vented rotors 
• JL Sahara/Rubicon rear: 13.4” x 0.55” (342mm x 14mm) solid rotors 
• JL Sport front: 12.9” x 0.94” (330mm x 24mm) vented rotors 
• JL Sport rear: 12.9” x 0.47” (328mm x 12mm) solid rotors 
• JK front and rear: 11.9” x 1.1” (302mm x 28mm) vented rotors (U.S.-spec)

Note(s):

• Requires a minimum wheel diameter of 17”. 
• On JK models, we recommend upgrading the stock master cylinder and brake booster to the Mopar Master Cylinder & Brake Booster Kit (# P5160050). Contact your Mopar dealer for availability.
