Assembled Magnitude 300
The Magnitude 300 is a fully assembled billet 4x4 transfer case built to outperform anything in its weight class. Born from the need for compact strength, this case delivers smooth, reliable shifting, extreme durability, and total confidence under real-world abuse. Whether you're crawling technical lines, hammering desert washes, or pushing a custom rig to its limits, this is the case that shows up ready.
Its strength far outweighs its size, giving it the ability to compete with physically larger transfer cases without the extra bulk.
No guessing. No parts hunting. Just bolt it in and send it.

You Can Tell This Was Built Right
Everything about it feels premium. It’s one of the few things on my rig I don’t have to worry about breaking.
-
Great Option for Race or Trail
I use mine for both wheeling and some short course racing. It’s held up great under both. I love how solid the shifting is compared to my old setup.
-
Bulletproof So Far
Been beating on it for a few months now and it’s held up perfect. Nothing loose, nothing worn. Shifts great every time. Couldn’t ask for more.
-
The case and customer service is great!
This case if amazing, I other companies should start building this level of parts. Works perfect and shifts amazing.
-
No More Fighting Shifts
I use front dig a lot and always struggled to shift my Atlas, this case shifts perfectly. Glad I switched!
-
Very Happy with this case
Everything lined up and went together without drama. The assembled version was worth it for me. Looks awesome and works even better.
-
Replaced my Behemoth
I’ve run D300s for years, tried the Behemoth case first because this wasn't available yet. Made the switch to Magnitude this is a whole different level. Better shifts, stronger parts, and the machining is beautiful. Total upgrade.

Exactly What I Needed
Running a tight build with not much room and this case made it all work. Showed up fully assembled and ready to go. No leaks, no issues. Love it.

Small, Strong, and Done Right
The assembled 300 showed up ready to drop in. Fit was perfect, and the compact size saved me a ton of hassle with driveshaft angles. Shifts great too.
