Hey truck owners and fleet managers!
If you're dealing with worn-out air springs on your International Prostar, these MVP replacements are exactly what you need.

These are direct fit replacements for Firestone W01-358-9875 and W01-358-1191, plus Goodyear 1R12-432 and 1R12-689 models.
The construction is seriously heavy-duty with a 4.5-5.00mm thick rubber layer that actually exceeds OEM standards.

The studs are made from 4140-grade steel that's 25% stronger than typical materials, and the composite pistons are built to handle rough road conditions.

The dimensions are spot-on too - 9.00 inch top plate, 10.00 inch piston width, and they weigh just 14.90 lbs each.

The extended height is 23.79 inches and compressed down to 5.96 inches, so you know they'll fit perfectly without modification.
What really sets these apart is the 3-year unlimited mile warranty - that's industry leading and shows how confident MVP is in their product quality.

Each spring goes through rigorous leak testing after final assembly too.
Quick tip: always double-check your part numbers with your dealer and compare your current air bag specs against the diagram to ensure perfect fitment.

Don't just go by make and model alone - taking that extra minute can save you the hassle of returns.

Whether you're a solo owner-operator or managing a full fleet, these air springs deliver the durability and performance you need to keep your International Prostar running smoothly and safely.

The quality feels premium and the direct fit design means installation is straightforward for any experienced mechanic.
