Xiali N5 1.3L Timing Chain Overhaul Kit 5 Piece for Naturally Aspirated Engine

Thickened link plates made of high-alloy steel with overall carburizing and quenching treatment to boost tensile strength and resolve the factory defect of easy chain elongation. The chain features dedicated timing alignment marks, delivering smooth and quiet transmission at idle and high RPMs, preventing chain skipping and valve collision. Optimized for frequent start-stop driving conditions of daily commuter vehicles.

Glass fiber reinforced wear-resistant PA66 base material with thickened shock-absorbing wear-resistant rubber layer and integrated reinforced aluminum bracket. Its curved surface fits tightly against the chain to dampen vibration and eliminate front-end rattling noise of cold engines. The rubber layer resists delamination and cracking under prolonged high temperatures.

Factory-positioned holes precisely restrict the chain to prevent lateral shifting and unilateral wear. The wear-resistant coating withstands engine oil corrosion, reducing friction loss between the chain and guides and extending the overall service life of the kit.

Aluminum hydraulic tensioning structure with built-in locking clip for pre-locking during installation. It automatically compensates for chain stretch clearance with stable oil pressure without pressure leakage, eliminating abnormal noise on cold startup and simplifying disassembly and assembly for timing calibration.

Integrated forged construction with precision ground tooth surfaces. Internal splines match the CA4GA1 crankshaft and camshaft at a 1:1 ratio, ensuring tight meshing without slippage to maintain accurate, stable valve timing and eliminate idle vibration and malfunction indicator light issues.
