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.

- 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

![Through an accelerated testing process dubbed the "ICON1K" R&D program, ICON has logged over a thousand miles in the dirt pushing the JL to off-road extremes to identify limiting factors in OE components, develop products that remove these limits, and further extrapolate performance out of this vehicle. This 2.5" suspension system has been tweaked, tuned, and revised several times over the course of this ICON1K testing in an effort to provide unparalleled ride quality and vehicle dynamics for everything from rock crawling to high-speed desert running.The ICON Vehicle Dynamics Stage 1 2.5" Suspension System for the 2018-UP Jeep Wrangler JL is designed for the driver looking to drastically improve the performance and ride quality of their vehicle. The Stage 1 system is ICON's entry level offering for Jeep enthusiasts looking to add lift height and wheel travel to their JL without breaking the bank. This system includes 2.5" lift dual rate coil springs, Vehicle Specific 2.0 Aluminum Series shocks, bump stop spacers, sway bar links, and all necessary hardware to complete the installation. With this combination of components, ICON was able to increase wheel travel numbers by over 30% (3" front, 2" rear), redefining the potential of the 2018-UP JL. The Stage 1 system allows for fitment of 35" tires when used with ICON's recommended wheel specifications. For users looking to install 37" tires, an optional extended bump stop spacer kit (PN: 22029) is available.Holistic Engineering - the ICON DifferenceWhen developing suspension components for a new vehicle, ICON takes a different approach than many others. Rather than focusing in on one particular part, ICON engineers look at the vehicle as a whole, identify inherent strengths and weaknesses, and set a target for performance. With a focus on maximizing wheel travel and improving ride quality, ICON will develop components that address (and often times replace) OE limiting factors. This "holistic engineering" philosophy often results in the development of several parts designed to work together as a system to provide a balanced on and off-road performance upgrade. Because ICON is designing and manufacturing all of the components necessary to improve the performance of a vehicle from front to back, end-users can rest easy knowing they are dealing with ONE manufacturer, ONE standard of quality, and ONE awesome warranty to back it all up.2.5" lift heightFits 35" tires (37" with optional extended bump stop spacer kit PN: 22029)3" front, 2" rear increase in wheel travelImproves on and off-road ride quality over stockDual rate coil springs with lifetime guarantee against sagging/breakage2.0 Aluminum Series shocks with vehicle specific valving100% bolt-on system makes for an easy install"ICON 1K" tested under rigorous off-road conditions to validate tune, performance, strength, and durabilityTECH INFO:Recommended wheel and tire fitment is based on a JL RubiconAdvertised lift heights based on a stock, 4 door JL RubiconWHEEL & TIRE FITMENT INFO:OEM Wheels & Tires: Yes[NON-RUBICON]Aftermarket Wheels: 8.5" Wide, 4.5" backspaceAftermarket Tires : 35" x 12.50 (Larger tires will fit with recommended bump stop spacer kit and minor trimming)[RUBICON]Aftermarket Wheels: 8.5" Wide, 4.75" backspaceAftermarket Tires: 35" X 12.50 (37" tires will fit with recommended bump stop spacer kit PN: 22029)SYSTEM COMPONENTS:22021 (QTY.1) | 18-UP JL FRONT FIXED LOWER LINK KIT22022 (QTY.1) | 18-UP JL FRONT ADJ UPPER LINK KIT22023 (QTY.1) | 18-UP JL REAR ADJ LOWER LINK KIT22024 (QTY.1) | 18-UP JL REAR FIXED UPPER LINK KIT22025 (QTY.1) | 18-UP JL 2.5" FRONT DUAL RATE COIL SPRING KIT22026 (QTY.1) | 18-UP JL 2.5" REAR DUAL RATE COIL SPRING KIT22027 (QTY.1) | 18-UP JL FRONT ADJ TRACK BAR KIT22028 (QTY.1) | 18-UP JL REAR ADJ TRACK BAR KIT27821CP (QTY.1) | 18-UP JL 2.5" FRONT 2.5 VS RR CDCV PAIR27726CP (QTY.1) | 18-UP JL 2.5" REAR 2.5 VS PB CDCV PAIR](https://cdn11.bigcommerce.com/s-de2pt6jzk5/images/stencil/590x590/products/3275/6419/K22018-2__88869.1627600018.jpg?c=2 "Through an accelerated testing process dubbed the \"ICON1K\" R&D program, ICON has logged over a thousand miles in the dirt pushing the JL to off-road extremes to identify limiting factors in OE components, develop products that remove these limits, and further extrapolate performance out of this vehicle.
