MMR 444032 4V / DOHC Billet Secondary Tensioners & XHD chain kit


MMR Billet Passenger side DOHC Secondary tensioner and Heavy Duty Secondary chain kit.

It has long been known that the factory passenger side secondary tensioners on ALL DOHC's tension the chain on the wrong side, this creates cam timing errors as great as 7 degrees (regardless of how the cams are degreed!) This new kit from MMR brings the margin of error down to a mere 1 degree. Properly tensioning the chain and adding the heavy duty chains allows you to degree the cams perfect every time and testing has shown 4-5MPH gains in the 1/4 mile! Get your timing under control with this kit today- a must for any High HP application!! As used by team MMR to produce 3000HP and 10,000rpm. The driver tensioner from the factory leaks between the cylinder head and tensioner, reducing oil to the camshafts and cylinder heads which cam create timiing variances and broken secondary chains. A must for all applications with aftermarket valve springs AND / OR cams. Also fits 2007-2014 GT500. Anodized for corrosion resistance.
