Key Features

• 6061-T6 Aluminium Construction — The mounts are precisely machined from 6061-T6 aluminium, a premium aerospace-grade alloy that offers unmatched strength and precision engineering, ensuring your portal axles remain perfectly aligned and protected even during the most demanding RC crawling sessions on unforgiving terrain.
• Red-Anodised Finish — Each mount receives a brilliant red-anodised coating that serves dual purposes: it delivers stunning visual appeal that elevates the appearance of your TRX-4, whilst simultaneously providing a protective barrier against corrosion, moisture and UV damage that would otherwise degrade bare aluminium over time.
• Left and Right Mounts Included — This package includes both the left and right rear portal drive axle mounts, meaning you have everything needed to upgrade both sides of your TRX-4's rear axle in a single purchase, eliminating the need for separate transactions.
• Perfect OEM Fit Guarantee — As genuine Traxxas components manufactured by the brand for their own vehicles, these mounts guarantee a hassle-free, perfect fit with your TRX-4 chassis, eliminating compatibility concerns and ensuring professional results every time.
• Hardware Included — The package comes complete with four 2.5x16mm countersunk screws (CS), providing all the fasteners you need for secure, reliable installation without hunting through spare parts boxes.
• Lightweight Performance Enhancement — By upgrading to aluminium portal mounts, you reduce unsprung weight whilst maintaining exceptional rigidity, which translates to improved handling characteristics and better overall performance on technical terrain.
• Precision Engineering — Each mount is carefully machined to exacting tolerances, ensuring perfect geometry and alignment of your portal axles, which is critical for maintaining proper articulation and preventing binding during extreme suspension movement.

Technical Performance

The Traxxas TRX-4 aluminium rear portal drive axle mounts represent the pinnacle of precision engineering for 1/10 scale crawler chassis modifications. Constructed from 6061-T6 aluminium, which is the same material specification used in aircraft construction and high-performance automotive applications, these mounts deliver exceptional rigidity whilst maintaining a lightweight profile. The 6061-T6 alloy is chosen specifically for its superior machinability, allowing Traxxas engineers to create precise mounting points and geometry that ensures perfect alignment of your portal axles. The red-anodised finish applied to each mount creates a hard, corrosion-resistant surface that protects the aluminium substrate from oxidation, moisture ingress and UV degradation—critical considerations for RC vehicles that are regularly exposed to water crossings, muddy terrain and outdoor elements. The engineering of these mounts is specifically tailored to the TRX-4 platform, which is renowned as one of the most capable and popular 1/10 scale RC crawler platforms available to UK enthusiasts. The inclusion of four 2.5x16mm countersunk screws ensures secure, flush mounting that maintains the clean aesthetic whilst providing the clamping force necessary to keep your portal axles perfectly positioned during aggressive crawling. These mounts work in conjunction with the TRX-4's legendary portal axle system, which provides increased ground clearance and superior obstacle negotiation capabilities—essential features for tackling challenging rock crawling and trail climbing scenarios.

Frequently Asked Questions

• Are these portal axle mounts suitable for rock crawling and trail crawling? — Yes, absolutely. These mounts are engineered specifically for the TRX-4 platform, which is renowned as one of the most capable rock and trail crawlers available. The 6061-T6 aluminium construction provides the rigidity necessary to withstand the extreme stresses of technical terrain whilst the red-anodised finish protects against corrosion from water and mud exposure.
• Will these mounts fit my TRX-4 without modification? — Yes, these are genuine Traxxas components manufactured by Traxxas specifically for Traxxas vehicles. As OEM parts, they guarantee a perfect hassle-free fit with your TRX-4 chassis every time, with no modification or adjustment required.
• What tools do I need to install these mounts? — You will need a screwdriver or hex driver suitable for 2.5mm fasteners. Installation is straightforward and requires no special tools or expertise—most users can complete the installation in under 15 minutes.
• Can I use these mounts as a repair or replacement? — Yes, these mounts can be used either as an upgrade to your existing TRX-4 or as a replacement if your original mounts have been damaged. They are available in red-anodised finish, making them an excellent aesthetic upgrade if you're looking to customise your crawler's appearance.
• Are the mounts anodised for durability? — Yes, the red-anodised finish serves both aesthetic and protective functions. Anodising creates a hard oxide layer on the aluminium surface that resists corrosion, oxidation and UV damage, significantly extending the lifespan of your mounts compared to bare aluminium.
• Why choose aluminium mounts over plastic alternatives? — Aluminium mounts offer superior strength, precision and durability compared to plastic alternatives. The 6061-T6 alloy maintains exact tolerances under stress, ensuring your portal axles remain perfectly aligned during aggressive terrain negotiation, whereas plastic components can flex or warp under load.
• What is 6061-T6 aluminium? — 6061-T6 is an aerospace-grade aluminium alloy heat-treated to its optimal hardness state (the T6 designation). This specific alloy is chosen by Traxxas for its exceptional combination of strength, machinability and corrosion resistance—properties essential for precision RC components that must withstand extreme environmental conditions.
