TeraFlex 4403450 Delta Brake Kit w/ High Modulus Bridge - 5x5 Bolt Pattern; Wrangler JK, JL, & Gladiator JT

The TeraFlex Delta Brake Kit is the ultimate upgrade for JL/JK Wrangler and JLU/JKU Wrangler Unlimited models requiring increased braking performance such as heavy-laden overland rigs as well as Jeeps with oversized – and heavier – wheels and 33-42” tires. This simple bolt-on upgrade doesn’t require cutting, welding, or adapters. 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 Kit’s calipers feature a high modulus bridge, which greatly improves stiffness for reduced flex for consistent brake modulationConfirm wheel fitment with diagram attached to this listingSpecs: Minimum Wheel Diameter: 17” Minimum Back Spacing: 4.75” or less MUST VERIFY FITMENT W/ DOWNLOADABLE TEMPLATE Includes: High-Modulus Brake Caliper Kit w/ pads - front High-Modulus Brake Caliper Kit w/ pads - rear 14” x 1.25” vented rotors - front 14” x 1.25” vented rotors - rear 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/Unlimited 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 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 · Default · TeraFlex
