The TeraFlex JL/JLU_JK/JKU: Delta Brake Kit is the ultimate upgrade for JL/JLU and JK/JKU Wrangler 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.
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. The Delta Brake Calipers features a high-modulus bridge.
Fits:
  • JL Wrangler (2-door)
  • JLU Wrangler Unlimited (4-door)
  • JK Wrangler (2-door)
  • JKU Wrangler Unlimited (4-door)
  • Minimum Wheel Diameter: 17"
  • Back Spacing: 4.5" 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" bolt pattern - front (# 4403485)
  • 14" x 1.25" vented & slotted rotors w/ 8x6.5" bolt pattern - rear (# 4403486)
  • All necessary hardware

Features & Benefits:
  • Significantly improved braking performance over factory brake system
  • Balanced front to rear brakes tuned specifically for lifted vehicles
  • Brake bias & piston sizes optimized for Wrangler
  • Designed to work w/ stock proportioning valve & ABS
  • 100% bolt-on upgrade for easy installation

Front & Rear Calipers:
  • Opposed 4-piston caliper design w/ 2" 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 & 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 forged steel bridges w/ T6 6061 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 & release
  • Low-profile bridge accepts 14" diameter rotors behind 17" wheels
  • 1,000-hour salt spray tested zinc-& E-dipped coating on bridges & mounts
  • 300,000 psi steel formed hardware
  • Calipers feature built-in auto bleeding check ball, valve, & spring for easy bleeding
  • Hard-coat anodized, scratch-resistant piston bores

Front & Rear 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
  • Rotors feature 8x6.5" bolt pattern

Front & Rear Brake Pads:
  • Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub w/ increased pad life & reduce noise & dust
  • Drop-in pad design - no need to disassemble calipers to replace pads

Stock Brake Rotor Reference:
JL/JLU Sport front: 12.9" x 0.94" (330mm x 24mm) vented rotors
JL/JLU Sport rear: 12.9" x 0.47" (328mm x 12mm) solid rotors

JK/JKU 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/JKU 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.
  • JL/JLU_JK/JKU: Delta Brake Kit - Front & Rear - 5x5" Bolt Pattern (# 4403450) also available.
