If you’re diving into a manual transmission project, USA Standard Gear has got your back with a solid lineup of OEM and aftermarket components. Seriously, they’ve been in the game for over 50 years, so you know they’re the real deal. Whether you're wrenching on a classic ride from the '60s or tackling something more modern, they’ve got the parts you need to keep that manual transmission running smoothly.
Take, for instance, this Transmission Bearing and Seal Kit. It's built for the NP435 model, which is a 4-speed transmission that’s been a workhorse in many International trucks. The kit includes everything you need to give your transmission a refresh. The main case is a sturdy 10.75 inches long and made from cast iron, so you know it’s built to last. Plus, it features an 8-bolt aluminum top cover, which can make a world of difference when you’re working under the hood.
The kit's got a ball-style rear mainshaft bearing and a tapered input bearing, both of which are crucial for smooth operation. I’ve seen too many projects go sideways because of cheap bearings, so it’s nice to have quality parts right out of the gate. And the fact that it comes as a complete kit means you can get everything you need in one shot—no more hunting down individual pieces.
Here’s a quick rundown of what it fits:
So, if you’re looking to get your hands dirty and breathe new life into your International truck or Scout, this kit is a smart choice. It’s all about keeping things reliable and efficient, and with USA Standard Gear, you’re in good hands.
