These are proper, JWIS top quality automotive cam drive chains, made in Germany, NOT cheap industrial quality chain as most of the factors offer. It has taken me over a year to get access to this product - and believe me I don't fit cheap timing chains to expensive race engines if I can help it - no point in taking all that time & effort to get everything right to have it go off in 1/2 a season because the timing chain has stretched beyond use or worse still................!
If you are running an inferior product on your £4000 engine, you really should think again!
Available as Duplex or two types of Simplex (for those wanting the very minimum weight/drag on their cam drive)
