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: “We’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: “The 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: “As 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: “we 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”.

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!
