July 20, 2025 - Holy Grail Labs, a premier supplier of engineered upgrades to classic automobiles, announced the launch of a new collection of products specifically designed for the Honda Acty Kei trucks and vans.

The Honda Acty series, beloved by enthusiasts for its compact design, versatility, and rugged reliability, has become increasingly popular among importers and collectors worldwide. Produced from the 1970s through the early 2000s, these Kei vehicles are icons of efficient, practical transportation. However, as with many classic rides, aging components can lead to reliability issues that detract from the joy of ownership.

Building on our proven track record of delivering high-quality upgrades for models like the Mercedes-Benz W124 and various BMW classics, we're excited to extend our expertise to the Honda Acty lineup. Our new collection features four meticulously engineered products:

Honda Acty & Street Rear Wheel Bearings - A full set of high-quality rear wheel bearings for the second generation Honda Acty or Street Kei trucks and vans. These come pre-lubricated and have integrated dust shields, ensuring the correct amount of grease and minimize damaging road contamination.

Honda Acty & Street Rear Wheel Seals - Everything needed to replace both the outer and inner rear wheel seals on second generation Honda Acty or Street trucks and vans.

Honda Acty & Street Front Wheel Bearing Kit - Everything needed to replace the front bearings on second generation Honda Acty or Street trucks and vans. The high-quality bearings come pre-lubricated and have integrated dust shields, ensuring the correct amount of grease and minimize damaging road contamination. Retaining circlips are included.

Honda Acty & Street Transmission Axle Seals - Left and right transmission axle seals for second generation Honda Acty or Street trucks and vans.

These products are crafted with the same attention to detail and reliability that our customers have come to expect from Holy Grail Labs.

Installation for most items is straightforward, requiring no special tools and typically completable in under an hour, depending on the product. The collection is compatible with second generation Honda Acty and Street models.
