JSAUX Steam Deck Back Plate Replacement Kit

Opening your Steam Deck to replace the back plate does not automatically void your warranty in many regions, but you must be careful not to damage any internal components during the process. We recommend checking your local consumer laws and Valve’s specific warranty policy for your region before proceeding.

The installation is moderately straightforward, but it does require patience and steady hands. The kit includes all necessary tools and a set of anti-static gloves, and we recommend following a step-by-step video tutorial to ensure you handle the internal screws and components correctly.

Yes, the integrated aluminum alloy sheet and thermal grease work together to draw heat away from the internal components more effectively than the standard plastic back. This helps keep the device cooler during demanding gaming sessions, potentially reducing thermal throttling.

The dimensions of the JSAUX back plate are designed to closely match the original, so it should fit into most standard Steam Deck carrying cases without issue. However, if your case is extremely tight-fitting, the slightly different texture or button heights may cause a very snug fit.

The kit includes three sets of rear buttons—original, lower, and higher profiles—allowing you to customize the ergonomics to fit your hand size and grip preference. This can help reduce finger fatigue and improve accessibility during long periods of play.

The back plate is made from a durable ABS and PC blend, but like any transparent plastic, it can develop micro-scratches over time if subjected to abrasive surfaces. The improved anti-slip texture helps with grip, which also serves to keep the surface from sliding on flat surfaces where it might otherwise get scuffed.
