• Preset precision gear mesh so no manual mesh adjustments are required at assembly.
• Motor retention is independent from gear mesh to prevent gear binding during impacts.
• Interlocking front and rear bulkheads for chassis rigidity and consistent alignment.
• Motor mounts to the rear bulkhead to reduce flex and eliminate gear-crunching under load.
• Driveline is sealed inside the chassis to keep out dirt, grit, and debris.
• No body clips or hook-and-loop straps—battery retention and body mounting is simplified.
• Pivoting battery hold-downs for fast access and easier battery changes in the field.
• Adjustable battery hold-downs fit multiple battery sizes and secure packs better than conventional systems.
• Battery tray integrated into the chassis top brace to improve stiffness and tray security.
• Front energy-absorbing rubber bumper protects the chassis in forward impacts.
• Lower front and rear skids give added abrasion and impact resistance on rough terrain.
• High-strength glue and bead construction on tires for long-lasting adhesion to the rims.
• Integrated nerf bars protect the sides from rock and obstacle strikes.
• High-output steering servo wired into the receiver box to keep the chassis tidy and protected.
• New servo mounting system fully supports the case and improves durability.
• Double-shear, bearing-supported servo horn reduces strain on the servo shaft.
• Suspension geometry is engineered to maximize travel and steering angles for extreme articulation.
• Critical suspension points built with double-shear strength for added damage resistance.
• High-strength steel suspension pins are used throughout for long life and minimal flex.
• Suspension pin retainers are designed not to loosen or "back-out" during hard use.
• 4 mm machined pivot balls for tight, repeatable steering and suspension articulation.
• C-hub and steering block geometry maximize usable steering angle for nimble control.
• Adjustable roll center so you can tune handling for jumping or crawling situations.
• Fixed, high-strength camber and toe links provide predictable alignment under load.
• Steel upper and lower tie bars for secure steering link connections.
• Full-contact sealed bearings used in exposed locations to resist contamination.
• Machined aluminum threaded shock bodies for smooth damper action and easy tuning.
• Extra-large bore shock design with improved oil capacity for consistent damping.

• Lower seal cartridge includes an integrated wiper seal to keep contaminants out of the shock oil.
• Adjustable upper spring retainer allows fine spring preload tuning.
• Plastic shock caps with pivot balls simplify assembly and reduce binding.
• Fixed shock mounting locations for predictable geometry and repeatable setup.
• Lower spring perches are bolted on for secure spring positioning during hard use.
• Large 8 x 4 x 4-inch all-terrain tires deliver traction over dirt, grass, and rock.
• Dual-diameter wheels fit the big tire profile and protect the bead under impact.
• Tires use a specially formulated rubber compound tuned for the X-Maxx power levels.
• Two-piece foam inserts allow consistent tire shape and setup options for different terrains.
