Inboard boots protect the driveshaft from outside dust and keep grease inside. Having better retention of grease ultimately helps reduce friction and improve fuel consumption.
By providing dynamic sealed protection from rotation in both the gearbox and the wheel, inboard boots deliver a smooth, consistent ride and long-lasting performance - even when the vehicle is driven at top speed.
Inboard boots fit on the gearbox side of the driveshaft. They are close to the engine and the exhaust line, meaning they are designed to withstand temperatures as high as 165 degrees Celsius, while withstanding extremely high-speed rotation.
Simply better boots
- Trelleborg inboard boots are designed to adapt to the dynamic movements and plunge of the driveshaft, resist rotation, and retain a perfect seal, even at high speeds.
- Our inboard boots are built to handle the high temperatures: 165°C pick and 130°C constant—generated by proximity to the engine and exhaust line.
- Our inboard boots can be compressed and extended by up to 50% to adapt to variant wheel movements and steering-shaft changes caused by poor roads.
