April 2011: We have now sold more than 30,000 inner axle EcoSeals, so we thought we’d celebrate by writing an updated tech article! Please check out the tech article below, and help us celebrate this great milestone for our EcoSeal, the first-ever Heavy Duty Birfield Seal!

Our Marlin Crawler Heavy Duty Front Inner Axle EcoSeals are an amazing upgrade for your truck. If you are constantly replacing inner axle seals because of leaks or axle damage, or you just want to build the most bad ass Toyota front end possible, then these are the seals for the job.

Designed by Marlin himself and originally tested in 2005, these seals have been proven to stop leaks in the deserts of Panamint Valley, the rocks of the Hammers, the water crossings of Fordyce, the 10,000 ft high sierras of Dusy Ershim, the Sluice Box of Rubicon, the slick rocks of Moab, the mud of Tellico and the Great Smokey Mountains, trails in Arizona and Texas, the dunes of Pismo and Grover Beaches, and the dry lands of Tierra Del Sol and Truck Haven. They have been used in nearly every continent including countries such as Canada, Mexico, Australia, Germany, Japan, Russia, Chile, Iceland, England, China, Norway, New Zealand, Guam, South Africa, Puerto Rico, Indonesia, Philippians, Holland, Italy, Spain, and Denmark. Marlin Crawler isn’t just keeping America clean, it’s keeping the world free from oil leaks!

Please take a moment to read the tech article below to review the technology behind the EcoSeal. Applications include all 1979-1985 Toyota Hilux 8″ front axles, and all 1969-1/1990 Land Cruiser front axles including FJ40, FJ45, FJ55, FJ60, and FJ62. Order a pair of these along with a pair of our Special Fit Rear Axle Seals to ensure a leak free rig! Remember, always Grease the ID of any new seal before installation!
