What makes our single row kits the best
Our 90% genuine single row kits include a billet 4140 chrome molly vacuum pump sprocket. The only way to get a new OEM vacuum pump sprocket is to buy a whole vacuum pump from Nissan Australia which is about $800. Our vacuum pump sprocket is designed with a flat face to easily check sprocket alignment this can only be done with our parts and is critical for maximum chain sprocket and guide life.

Tensioners
The YD25.com.au kit includes genuine Japanese Tsubaki tensioners in their original Nissan packaging. These are the best available.  The top tensioner is supplied with an additional fail safe component designed and manufactured by us.  When new chains and guides are fitted, the fail safe component only allows the tensioner to back off 1.0mm. Without the fail safe, the tensioner can back off 7.0 to 8.0 mm which, when combined with 3.0 to 4.0mm of wear to the chain, can result in the chain jumping teeth. We have tested aftermarket tensioners and found high valve failure rates. These tensioners come in plastic bags or white boxes with no manufacturer stamp, name, or logo. Failed aftermarket tensioners have cost some owners their engine.

Don’t risk it!

Special Tools
A scissor gear tool is included in each kit to assist installers maintain the pretension between the scissor gear and the idler gear during removal and installation.  Failure to maintain the pretension and timing will cause vibrations putting undue stress on the engine's internal components.

We offer free hire on the harmonic balancer tools for Australian retail customers. These tools are essential to loosen, remove and re-torque the harmonic balancer. For those wishing to take advantage of this offer, a security deposit of $230 AUD (including a non-refundable charge of $25 AUD to cover freight one way) is required.  $205 AUD will be refunded on return of the tools in good condition.

Warranty
Correct chain running alignment between the vac pump and fuel pump sprocket is crucial for chain longevity. This can be achieved with our flat faced vacuum pump sprocket. The risk of using a worn vacuum pump sprocket is that the teeth will wear further and eventually come off causing vehicle brake failure or engine failure. Using a new chain on a worn vacuum pump sprocket voids warranty. Evidence that the vehicle has been serviced according to Nissan guidelines will be required to support a warranty claim. The warranty covers premature wear to chains and sprockets. Damage as a result of incorrect installation by anyone apart from us, other parts failing causing chain and sprocket damage or continuing to drive the vehicle when there is an unusual noise coming from the motor rather than having it repaired will not be covered by our warranty. All other timing chain components are covered by a 12month 20,000kms warranty.
