X-Maxx Alloy Upgrade Suspension

Custom MonstaMaxx-X-Maxx Trucks are a Specialty

Each mount has a degree of additional work involved in machining and is comprised from a different piece of material. The actual size of the mount may vary upon machining after material is removed to true the product. The 1/2" is not a 1/2" at the face but the base rails are approx. maintained at 1/2' as well the right angle braced corners are thicker/taller as is the same with the 4" Cradle, "our pride and Elite mount". There is nothing like it in the world. It is a premium high grade quality X-Maxx motor mount for Elite owners.

Why Did We Re-Engineer A New Chassis Design?

X-Maxx Anti-Bend Driveline Cube.

​It is the first of its kind. Simply slide it over the drivlineto then center of the chassis and lock down the skid plate which holds it in place. This custom machined Delrin part acts as a self lubricating bearing that gives added lateral support to your drive shaft and it aids in preventing the issues many of you have run into where your shafts have unknowingly bent. If you would like added support drill a shallow hole top down center and add your preferred choice of fastner. We have also given the option to purchase a Y grease chamber drilled within the Cube and you may purchase separately from your neighborhood hardware store a grease fitting and use it for additional lubrication beside the self lubricating qualities to aid in longer lifespan of the component.

Xtreme MonstaMaxx-X Custom Billet Chassis

Originally we were inspired by the KD chassis design after purchasing five initial chassis's, two for myself, and three for customers requesting that theirs be gone through and beefed up enough to handle the real abuse of a X-Maxx. After 4 weeks of not being able to obtain any more chassis's to utilize our new upper chassis design and maintain all the incoming requests we had plenty of time to completely reengineer the entire approach. Now we have a completely new design altogether that is incompatible with the KD chassis so none of Fastlane parts can be purchased and utilized with their system. The height of the chassis is as close to factory and we have a wopping 2" increase in length, two piece drive shaft with hangar bearing, full front and rear rail bulk head support, and all M5 hardware for massive ground breaking durability. We also have a Brand NEW Cryogenic Marine based polished chassis plate pictured above that can be seen in its glory next to the other and you can see why it is so beautiful and durable. This chassis is made for those extreme big air bashers and Lifetime Guaranteed (ask for details) engineered utilizing amazing techniques, basic stress testing, and material grade testing. You can be rest assured we use Aircraft and Cryobased Alloys and verify our material grade right here in Colorado USA. Not a single piece of 1000/2000 series alloys in any of our products. Our chassis offers real Delrin battery trays, Stainless hardware, and Every Part is hand polished to a mirror finish. While for some there may seem to be some similarities however there is not single part that will fit the other and  we have more than 35 man hours into redevelopment and correcting of the flaws and issues that result in a chassis that is designed how it needed to be from the beginning. Consumers need a product that can endure what they throw at it and not the same ole in todays disposable society. When we are constantly hearing online about product issues we felt it was necessary to step in and do something about it when consumers are spending their hard earned money and sometimes a weeks earnings or more. When a product is failing then by all means it is time to redesign and not ignore those people that continue to tell you about all the issues they are having. At Fastlane we are constantly striving to redesign and better our own product all the time it is like computers they constantly upgrade as time goes on. We don't ever feel satisfied with one single design. This keeps us busy working hard for you. Thank You for supporting Fastlane Hobbies, our R&D Dept.., our on-going ventures to provide excellence and a better RC experience for our customers with a High Quality product that we can proudly stand behind and you can run without worrying about it being a fragile and broken product.


Notice the extra attention to detail? The durability? Threaded Holes versus nuts and screws. As Each stage of Chassis is completed further details are improved upon.

The Lower Skid Kits are made per order and will require a 2-3 week turn around from time of purchase as with many custom parts that are made to order. If you have a factory Traxxas Chassis please call or text and let us know so we can make adjustments for your application. Minor modifications may be required.
