Grinding gears in your 6-speed? This synchro assembly from USA Standard Gear is exactly what you need for that NSG370 transmission. It covers the 1st and 2nd gear synchronizers - the ones that usually take the most abuse. Just so you know upfront: this doesn't include the synchro rings, you'll need those separately if yours are shot. Perfect for when you're rebuilding or fixing up a Jeep Wrangler TJ/LJ, Dodge Dakota, or other vehicles with the NSG370 6-speed box. USA Standard Gear knows drivetrain parts - they make everything from ring and pinions to bearings, so this is quality stuff. Makes your repair job way easier than hunting for individual pieces. If you're doing a transmission rebuild, this synchro assembly will get those first two gears shifting smooth again. Just match it up with your transmission model and you're good to go. Get it done right the first time with parts that actually fit and work like they should.
