Does the Alcon Front Big Brake Kit for Jeep Wrangler JL also fit the Gladiator?

Yes. Alcon lists the Front Big Brake Kit for Jeep Wrangler JL for both the JL Wrangler and the JT Gladiator, which share the front axle and brake mounting. Turn 14 lists it for the Dana 44 front axle with 5 x 5 inch hubs, so check with BA if your truck runs an aftermarket axle.

Does the Alcon Front Big Brake Kit for Jeep Wrangler JL work with the factory ABS?

Yes. Alcon designs its truck kits around the stock ABS system, so the Front Big Brake Kit for Jeep Wrangler JL installs as a plug-and-play upgrade without extensive modification, and the anti-lock, traction and stability systems keep working as they did with the factory brakes.

Is a big brake kit worth it on a Jeep Wrangler JL or Gladiator JT with larger tires?

For most built trucks, yes. Bigger tires, armor and gear add mass the factory brakes were not sized for. Alcon measured up to 14 percent less disc temperature rise, up to 35 percent lower pad work rate, up to 6 percent more available brake torque and up to 10 percent less pedal effort against the stock system, gains that show most on long descents and when towing.

What are the calipers made from and how are they finished?

The calipers use ductile iron housings, which Alcon chose for strength, stiffness and resistance to impact and fatigue. They are finished in epoxy acrylic paint over an acid zinc base for corrosion protection, with high-temperature seals from the Alcon motorsport range.

Do I need to upgrade the rear brakes as well?

Not to fit the kit. The Front Big Brake Kit for Jeep Wrangler JL is a front axle upgrade and works with the factory rear brakes. Alcon also sells matching rear kits for many trucks, and BA can quote front and rear together for owners who want more capacity at both ends.

Description

Alcon Front Big Brake Kit for Jeep Wrangler JL and Gladiator JT

Alcon’s Front Big Brake Kit for Jeep Wrangler JL and Gladiator JT fits six-piston ductile iron calipers and 350 x 32 mm rotors to the front axle, the upgrade for a JL or JT that now carries larger tires, armor, a winch or a loaded bed. Alcon has built racing brakes since 1983, and in a truck kit that experience becomes brakes that stop the same way on the tenth descent as on the first. The kit is designed around the stock ABS, so it installs as a plug-and-play upgrade without hydraulic changes.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
