Teraflex JL JK JT Delta Brake System (Front & Rear) – 8 x 6.5” on Sale

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: 8×6.5”

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 8×6.5” – Front (# 4403485)
• 14” X 1.25” Vented & Slotted Rotors w 8×6.5” – Rear (# 4403486)

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).
