Why ChooseHongLi (JIUX)

The Timing Kits

Which meet or exceed OEM performance requirements, coupled with stable quality control, keep your engine's valve train in perfect time, all components come from one source and are therefore perfectly matched together.

Timing Chains

Timing chains are engineered and manufactured with precision pitch control to ensure optimal chain-to-sprocket fit reducing noise, minimizing stretch, and maintain accurate timing.

Timing Camshaft and Crankshaft Sprockets

Timing Camshaft and Crankshaft Sprockets are precision-tooled with exact tooth geometry and a perfectly matched bore for superior fit, minimizing the risk of slippage and ensuring that power transmission is smooth and efficient.

Heat-treated Steel Constructing

Heat-treated steel constructing for increased strength and wear resistance, delivering long-term durability even in high-heat, high-stress environments.

Guides

Using Nylon raw materials imported PA66/PA46, it is more resistant to high temperatures and wear, no deformation or melting and can better guide the transmission direction of the chain.

Tensioners

Precision machining in order to obtain reduced internal clearances for the best control and optimal management of the chain tension.
