Press Releases:

The announcement follows Alcon’s new product launch of the LC300 and Tundra kits in September 2021. Since then, they have received orders from a number of the world’s premier vehicle armorers who are all developing their own LC300 armored variant designs. As well as multiple un-named clients,

Launched by Toyota in June 2021, the new 300 series Toyota Land Cruiser has already been taking the market by storm and is expected to follow in the footsteps of its 78/79 and 200 series predecessors, becoming the vehicle of choice for armored defense, security and NGO use, globally. All of the major vehicle armoring companies now have an LC300 armoring development program in place to design and certify their protection systems. Alcon are able to offer a ready-made solution for the essential brake upgrade required to accompany the weight-adding armored modifications, where the stock braking system will become challenged, affecting performance but more importantly, safety.

Alcon’s new LC300 kit is similar to the already well-proven LC200 kit but adapted to fit the new vehicle and engineered to match the new vehicle dynamics and the increased levels of technology and complexity present in the new Toyota base vehicle design. Fitting the brake upgrade kit will increase available brake torque, reduce brake fade and fluid vaporization, extend brake service intervals and reduce through life costs.

Jonathan Edwards, Group Sales Director at Alcon said: β€œWe’re very pleased to announce the dispatch of these new brake upgrade kits today that will be a welcome addition for the entire armored vehicle market, that is currently developing and certifying their new armored Toyota LC300 designs”.

He added: β€œThe team have developed multiple off the shelf solutions to meet the requirements of OEMs and vehicle modification companies and this new LC300 kit adds to that story. Our partners and agents are already working hard to supply our class-leading kits to the global armored vehicle markets and getting this first batch out of the door is a major milestone”.

Jonathan Simmonds, CEO of MSW Auto Spare Parts said: β€œAs Alcon’s premier defense and security sector agent, we see the LC300 kits building on the enormous success of the LC200 predecessor kits and have therefore placed a significant first order with Alcon. Together with MSW’s market leading heavy duty wheel rims and assemblies, the Alcon brake upgrade significantly increases capability but more importantly, safety as the increased weight of the armor systems changes the vehicle dynamics”.

He added: β€œwe have supplied Alcon brake kits to all of the Middle Eastern based vehicle armoring companies for well over 10 years and this new Alcon LC300 kit will continue to deliver the quality and performance they need and expect”.

Alcon Big Brake Kit common questions

Alconkits - the primary Alcon distributor

Why should you buy direct from AlconKits.com?

General retailers and marketplaces list Alcon brake kits, but they typically cannot advise on fitment, wheel clearance, pad compounds, or long-term service parts. You can buy Alcon Brakes from lots of places - but you SHOULD buy them from Alconkits.com. Alconkits.com is a specialist distributor focused exclusively on Alcon systems.

What support do I get when buying from Alconkits.com?

You get brake experts live every time. We answer the phone with 25 years of Alcon Brakes support. Our experts will help you choose the right kit, with the right fit, guaranteed. Plus, when you need replacement parts and service knowledge, you will only get that from Alconkits.com - not someone who just sells general automotive parts.

What happens if I need pads, rotors, or service parts later?

This is an excellent question to ask. We stock replacement parts for everything we sell - and maintain a full cross-reference catalog for all compatible parts. When you buy from Alconkits.com an authorized primary distributor of Alcon Brakes you will get a lifetime of advice and support that other vendors cannot match.

Is Alconkits.com an authorized Alcon distributor?

Yes. You can find authorized dealers on the manufacturers website - and we are seen as one of the largest most knowledgeable dealers in the world, and certainly in the United States.

What are the main reasons people choose Alconkits?
  1. Factory-engineered systems designed for brake performance and durability require expert advice
  2. Lifetime technical support included when purchased from Alconkits.com.
  3. Support beyond just sale, we help you select pads, ensure fitment, and service your brakes.

In short, you want an expert driven purchase decision, from a vendor that provides value beyond the product, with service, support, and expertise. That is the Alconkits.com promise delivered every day.

Installation

What tools do I need to install?

Our brake kits require common hand tools for installation. You will need a torque wrench, brake fluid (2 pints), and loctite.

What if I run into issues while installing?

We pride ourself in expert advice. You can call or text us at 630-360-2548 for expert technical and installation advice.

Are any other modifications required?

For OEM installations where wider rotors are fitted, you should expect to remove or trim the rotor dust/heat shield. This often interferes with larger rotors but is no longer needed due to our upgraded components.

Will I need a new Master Cylinder

No. All of our brake kits are designed specifically to work with the hydraulic ratio of your stock master cylinder

Do I need wheel spacers

We provide a fitment template for you to check clearance in advance. In some cases a small spacer may be required and we provide those when we are sure they are needed.

Are brake pads included?

Yes. We include the appropriate brake pads for all our brake kits. In some cases we offer multiple compounds for you to customize your experience. We stock a wide variety of pads for Alcon Brake kits here.

Break In questions

Do I need to brake in new rotors/pads?

Yes! We highly recommend following our brake pad/rotor bed in process. This ensures that an even layer of pad material is deposited on the rotor to eliminate shudder, increase rotor life, and to heat temper the new rotors for longer life.

What about noise and dust?

Noise and dust are related to the brake pad compound. Higher temp pads have more metallic composition and will therefore increase potential noise and dust the more aggressive the pad. For squealing issues we recommended loosening the caliper and re tightening it. This will sometimes change the caliper "frequency". Additionally "sticky shims" or our titanium pad shims will reduce noise.

Operational Questions

Is this compatible with my ABS?

Yes! We test our brakes to ensure they are fully compatible with your stock ABS on all models we release.

How long do they last?

Lifetime of components is massively variable based on how they are used. High dust/dirt/salt environments will wear seals out more quickly. Heavy Duty or Track use will also affect rotor and pad life.

What is the warranty?

We support the manufacturers 12 month/12000 mile warranty against factory defects and material issues. You can find more details here.

Man. These stop so incredibly well, and still fit the 17in wheel!…unlike all of the other big brake kit options. My supercharged long travel truck was in dire need of brakes that could keep up. These are it! Will be getting the rear ASAP.

LX570 Front & Rear Stage 2 Kit

Finally got this kit installed and the descriptions are 100% accurate. The brakes stop hard and required pedal effort is lower. A welcome surprise was modulation has improved over the OEM brakes. It took a while to arrive to the US with the global shipping situation but well worth it. Chris and Joe were extremely helpful throughout and in constant communication. You can't go wrong with these.

Tundra front and rear BBK

Have had these brakes on my 2018 Tundra for some time now. Hands down huge improvement over stock. My son is now running these on his Tundra also. Extremely satisfied with this upgrade. Alcon has been easy to work with.
Highly recommend this setup, front and rear for any Tundra.

Great Customer Service

I ordered my Roush / Alcon brake kit online and the next day I received an email from Chris just to confirm my application and to make sure it would work. I called Chris the next day to thank him for taking the time to make sure I was happy. I have yet to install my kit, I will have that done at SVC Offroad in Utah later this month with the rest of my Raptors build. That said, the parts did arrive in a timely fashion and were well packaged. So far, I am quite satisfied with this purchase and follow up customer service.

Such good brakes for my Tundra

Bought the front and rear kit after we did a lot of add-ons for my Tundra - what a difference stopping now. I'm not scared on the highway when we're loaded up for a trip with all the gear, roof tent, etc... Everyone should do this upgrade - and sooner than you think!

Such good brakes for my Tundra

We put a ton of modifications on our Tundra and braking was getting just a bit lazy. Can't believe I waited so long to do these - they're amazing. No longer worried on the highway about stopping in time.
