Buying Guide
Finding the right 12 bolt gear is vital. It keeps your truck or car running well.
Many drivers love the smooth feel of new gears. One user said his truck felt brand new. He noticed less noise on the road. The power was much better too. It made his daily drive very fun.
Gear Ratio
The ratio tells how fast your wheels turn. Low numbers give better gas use. High numbers help you tow heavy loads.
Steel Quality
Look for high grade steel. It must be very strong. Good steel will not break under heat.
Brand Name
Choose a brand with good reviews. Trusted names make parts that last long. This saves you money later.
Fitment
Check the size of your axle. The gear must fit your 12 bolt housing. A wrong fit will fail.
Heat Treatment
Good gears go through heat steps. This makes the metal very hard. Hard metal stays quiet and smooth.
Price
Compare the cost of different sets. Do not pick the cheapest one. Aim for the best value instead.
Installation Kit
Buy a set with shims and bolts. This makes the job much easier. It ensures the gears align right.
Warranty
A good deal includes a warranty. It protects you from bad parts. Look for at least a one year plan.
