Chain and Tensioner Parts

A guide rail prevents irregular motion in the timing chain as it moves around different pulleys. Car Parts 4 Less offers marked-down prices on timing chain guide rails for every make and model of car.

The guide rail keeps your timing chain taut and in place as it moves around the different pulleys. This maintains the engine cycle by opening and closing valves at just the right moment. Without the guide rail in place, the timing belt could come loose and cause the valves to knock into the pistons. This could cause catastrophic ? not to mention costly ? damage. Like every other part, the timing belt guide rail can wear out, come loose and break. To avoid spending a fortune on engine repairs, we advise checking the guide rail regularly. If the chain does come loose at any point or starts rattling and whining, these could be signs that you need a new guide rail. Find the right guide rail for your timing belt using the parts-finder tool on this page.
