Gear upgrade advice on 7.25 axle with 2:76 gears

I have found somewhere I can get a 3:55 ring and pinion but wondered if this would be a straight swap or if I need to change anything else at the same time? Any advice appreciated but I'm new to this so go easy!

Thanks all.

As long as the 3.55s are for a 7.25, it should be pretty much a straight swap - as long as whoever is doing the work knows what they are doing.
