CNC Metal Adjustable Magnetic Body Mount Conversion Kit for TRX-4

Replace the external body-clip removal routine with quick-release magnetic mounting. This CNC metal conversion kit is intended for original post-and-clip Traxxas TRX-4 bodies, with mating front and rear plates beneath the shell.

TRX-4 applications

• Land Rover Defender — original clipped-body model 82056-4
• 1979 Ford Bronco — original clipped-body model 82046-4
• 1979 Chevrolet Blazer — original clipped-body model 82076-4
• TRX-4 Sport — original clipped-body model 82024-4

These original models share the Traxxas 8215 body-mount assembly. Published TRX-4 magnetic-mount designs document 72 mm and 82 mm post spacings; published measurements for the Sport Camper body 8112 specify 72 mm front and 82 mm rear, measured centre-to-centre across each pair of body-post holes. Both spacings fall within this kit’s 55–85 mm adjustment range. Application to the models above is based on the shared mounting system and dimensional comparison, rather than a physical test of this kit on every body.

For the original body-post-and-clip arrangement only. Body style alone does not identify the mounting system. A suspension lift does not by itself establish or rule out fitment: retain the matching clipped-body mounting arrangement and check shell height and clearance. Modified mounts and aftermarket shells require their own measurements.

Specifications

• Version: CNC metal, black finish
• Adjustable mounting centre spacing: 55–85 mm, not wheelbase or height
• Vendor-stated magnet dimensions: 20 × 15 × 5 mm
• Vendor-stated metal-version weight: approximately 137 g
• Front and rear magnetic mounting pairs

Installation

1. Remove the body. Measure centre-to-centre across the left and right body posts separately at the front and rear.
2. Dry-fit and adjust the chassis-side plates to the post spacing. Select the suitable supplied spacers and fittings for the post diameter and required body height.
3. Align the mating plates beneath the shell, keeping the body centred and the magnetic contacts fully aligned.
4. Secure the chassis-side and body-side components using fixings suitable for the actual shell and mounting arrangement. The supplier images do not specify a universal body-side fixing method; additional fixings, adhesive or body modification may be needed.
5. Check secure retention, battery access, full steering and suspension travel before driving. Lift the shell away at the magnetic interface for routine removal.

In the set

• Four mounting plates forming front and rear mating pairs
• Magnetic contact assemblies
• Screws, nuts, spacers/adaptors and four body clips as pictured

The supplied clips are installation hardware; routine shell removal separates the magnetic interface. Vehicle and body shell are not included. No universal no-drill installation or magnetic holding-force rating is specified.
