370 Ring Gear & Pinion Kits are always highest quality gears.
NOTES: All TPI Land Cruiser Precision Gears are the stronger fine spline pinion and use a crush sleeve. You will need to purchase a Fine Spline Flange if your Cruiser is 1977 and earlier. All models require a Major Install Kit #41231-PG1 which comes with all your bearings, seals and crush sleeve. If you are installing an ARB Air Locker you will need to notify us. You may need different Carrier bearings.
