Rear Hub Inner Oil Seal Assembly OE 31RAS01-04080 for Dongfeng GX&KX | Genuine Truck Part

This rear hub oil seal assembly OE 31RAS01-04080 is manufactured strictly to Dongfeng GX&KX original design specifications, adopting a precision double-lip structure that provides dual-layer protection against oil leakage and contamination. The product is crafted from high-grade nitrile rubber (NBR) with excellent oil resistance, wear resistance and temperature stability—ideal for heavy-duty axle operating conditions. The integrated self-tensioning spring maintains consistent lip pressure, ensuring a tight seal even under vibration and thermal expansion. It adopts a 1:1 original dimensional design, with precise outer diameter and groove tolerances that perfectly match the truck’s rear hub and axle shaft, ensuring a secure, leak-proof fit. This robust design combines superior sealing performance and durability, making it the ideal OEM replacement for Dongfeng GX&KX heavy-duty trucks.

Fully compatible with all applicable Dongfeng GX&KX truck models, this rear hub oil seal assembly can be quickly verified via OE 31RAS01-04080 to ensure accurate matching. It solves multiple common failures caused by low-quality aftermarket seals: inferior rubber leading to hardening and cracking, single-lip design failing to prevent contamination, mismatched dimensions causing installation gaps and oil leakage, and poor wear resistance leading to premature seal failure. A faulty oil seal will cause lubricating oil loss, leading to bearing wear, hub corrosion and even rear axle breakdowns—posing a serious threat to driving safety and fleet operation. By using this genuine double-lip seal, users can eliminate oil leakage, corrosion and bearing failure problems, ensuring reliable rear axle performance.

As a key component for heavy-duty truck axle systems, this rear hub oil seal meets Q/DFL 6020-2021 Dongfeng automotive parts quality standards and has passed authoritative third-party tests for oil resistance, wear resistance and leak-proof performance. Test data shows the seal maintains zero leakage after 10,000 hours of continuous operation under heavy load, resists hardening and cracking after 500 hours of high-temperature aging, and remains functional in extreme temperature cycles (-40℃ to 120℃). Each seal undergoes 100% dimensional inspection, lip tension testing and leak detection before leaving the factory, ensuring complete consistency with original factory parts in performance, durability and fit. It performs reliably in all operating conditions, with strong resistance to oil, wear and temperature fluctuations. Backed by complete factory traceability and quality certification, it provides users with long-term, trustworthy axle sealing performance.
