12V Starter for Toyota Trucks: Fitment and Buying Guide
Author : Danny walker | Published On : 13 Oct 2026
When Your Truck Won’t Start
It’s a bad feeling when you turn the key and nothing happens. Sometimes the cause is a weak battery or a loose cable. Other times, the starter motor is worn out.
If you drive a Toyota Tundra, Sequoia, Land Cruiser, or Lexus LX 570, you need the right replacement starter. Voltage alone won’t tell you the part fits, so also check the part number, engine, model year, and mounting.
Quick answer: This 12 V, 1.5 kW starter replaces Toyota and Lexus part numbers 28100-0S050 and 28100-38080, and Denso 428000-9091. It is listed for the 5.7L V8. Always confirm the fit with your VIN or old part number.
What the Starter Does
The starter uses battery power to crank the engine. Its pinion gear locks into the engine’s ring gear and spins the engine until it runs on its own. This one has a PLGR (planetary gear reduction) design.
Signs of a Failing Starter
Watch for a single click, repeated clicking, slow cranking, no response, or grinding at startup. These signs don’t prove the starter is bad, so test the battery and connections first.

Fitment
All listings are for the V8 5.7L engine:
- Toyota Tundra: 2011–2015

- Toyota Land Cruiser: 2011, 2013–2016

A missing year doesn’t tell you whether the part fits, so check your VIN.
Test Before Buying
Check the battery, cables, and starting circuit first. Then have the starter tested and compare your old part number with the ones above. Don’t replace the starter just because of clicking or slow cranking.
Installation Tips
Read the service manual first. Disconnect the negative battery terminal, protect the wiring, check the mounting area, and use the correct bolt torque.
Choose the Right Replacement Starter
A good starting system needs more than the right voltage. Matching the part number, engine, mounting, and electrical specs lowers the risk of buying a part that doesn’t fit.
If you are shopping for a 12V starter for Toyota trucks, use the listed part numbers as your starting point. Then confirm your exact vehicle details before you buy. A correct match makes the install easier and helps your engine start reliably again.
