1F Rocker Shaft O-Rings (2-pcs) Toyota Land Cruiser -RL1040 (EN2-5)
ALL IN EFFORT TO SAVE AN F!
Fs are bad on the report card, but under the hood of your Toyota Land Cruiser, Fs are good and GREAT! We help you make them great again by spending painstaking hours researching the correct 1F Rocker Shaft O-rings, as Toyota has long discontinued them.

We are dedicated to the Toyota F-Series of engines at Red Line Land Cruisers. We love the simplicity and reliability of these old F-Series engines, and we strive to preserve them through proper maintenance. We are constantly exploring ways to keep them as reliable as the day they rolled off the assembly line, while also extracting some “hidden” reliable performance gains.

However, as Toyota has gradually discontinued service parts, Red Line Land Cruisers has remanufactured these “factory” parts to ensure proper service and maintenance of the Toyota F-Series engines, which are typically 35 to 50 years old. Oil is life for these old combustion engines, and appropriate maintenance is the key! Unfortunately, Toyota has discontinued what we consider critical parts essential for the survival of these old rigs.

The F-Series Toyota Engine is worth saving because it’s rarer than the FJ40s it came in! Many Toyota Land Cruiser owners replaced the original power plant in the early years with small-block Chevy engines. But with enough time, we all want to go back in time and start all over. Luckily, some of you saw the original magic of the F-Series inline-six engines and stayed with it! The Toyota F-Series engine, an inline six, is both simple and reliable when properly maintained.
