Speedfactory Heavy Duty tensioner spring (Honda B-serie engines)
80% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
















Tired of trying to consistently set your timing belt tension to a suitable level for your high-performance B-Series engine? Those days are over thanks to our solution to this common problem.
The SpeedFactory Racing B-Series HD Timing Belt Tensioner Spring is made from durable & corrosion resistant 302 stainless steel and is over 7x stronger (the OEM spring is very weak & we found the need for a much higher spring rate).
This high-quality spring gives your timing belt the proper tension level for high-performance and racing applications, especially when using a heavy-duty racing timing belt (such as TODA or Gates Racing) which are much stiffer & stronger than an OEM type belt.
Not enough tension (OEM spring) and you get excessive belt deflection with poor cam timing control and a high risk of jumping teeth resulting in expensive valve damage or worse.
Pulling on the tensioner with a hook to try and get enough tension has been a work-around but yields non-repeatable results at best and easily results in over-tightening which can cause undue stress on the belt and cam journal wear issues.
This is what we use for our own top level engine builds with no other form of additional tensioners - race proven up to 12k rpm even with violently disrupting the engine via ignition shift cuts and rev limiters.
No timing belt skipping, no cam journal wear issues, just reliable and consistent belt tension that works!
