Tired of trying to consistently set your timing belt tension to a suitable level for your high-performance D-Series engine? Those days are over thanks to SpeedFactory's solution to this common problem.

The SpeedFactory Racing D-Series HD Timing Belt Tensioner Spring is made from durable & corrosion resistant 302 stainless steel and is over 6x stronger (the OEM spring is very weak & SpeedFactory 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 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 SpeedFactory uses for their own top level engine builds with no other form of additional tensioners.

No timing belt skipping, no cam journal wear issues, just reliable and consistent belt tension that works!

Fitment:
1988-2000 D15 & D16 engines

Lifetime warranty against manufacturing defects.

NOTE: Reuse the rubber sleeve from the OEM spring if present (provides vibration damping for spring longevity).

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.
