Extra heavy valve spring rod suitable for both old-fashioned cylinder heads and modern heads with deep-lying (recessed) valves. Due to its large lever and heavy construction, this valve spring tensioner is also very useful for larger cylinder heads, with or without extra heavy or double valve springs. Thanks to the convertible valve pin adapters, you can also use it to use various smaller car cylinder heads. This makes this XL valve spring tensioner one of the most versatile pliers on the market.
