    Crane Gold Race 1.7 roller rockers - new

    Once again, I have no money after paying some unexpected bills so a few parts have to go.

    Part number 144750-16

    Crane Cams 98-06 LS1-LS6 Variable Ratio Rocker Arm Pushrods, rocker arm studs and guideplates

    An easy bolt-on that’s good for 15-20 horsepower gain in LS1/LS6 engines. These highly efficient Crane rockers employ Crane’s unique new “Quick-Lift” design technology that accelerates valve events for more flow and improved performance. By relocating the pushrod seat down and in, Crane engineers have created a “variable ratio” rocker arm that begins with a ratio of about 1.78:1 and converges to a standard 1.7:1 ratio as the valve reaches a lift point of .250-.300”. This produces a significant improvement in bottom-end and mid-range power. These rockers are great when used with stock LS1 cams, and even more power can be had when they are used with a Crane “Quick-Lift” Z Cam profile. The “Quick-Lift” feature allows use of a milder profile to produce the same or more power than a considerably more radical cam and valve train. With Z Cams and Crane “Quick-Lift” aluminum rockers you maintain engine vacuum, have no effect on the factory ECU and enjoy great street driveability. When you stand on it. . . it’s all there! These rockers are also engineered to be the quietest operating needle-bearing trunion supported rockers available. They run quietly, without the valve train noise that is known to trip factory “Knock Sensors”, which retard spark advance timing and rob up to 20 HP from the rear wheels! Another feature is these rockers is that they fit under stock factory rocker covers. With Crane rockers there’s no need to buy expensive, “tall” aftermarket LS1 rocker covers! These rockers are part of Cranes “Gold-Race” rocker family, precision CNC machined from extruded billet aluminum bar stock. They are available as a complete kit or individually. The kit includes pushrod guideplates, rocker studs, pushrod guideplates, heat-treated chromemoly pushrods, and lock-nut style rocker adjusting nuts.

    This is a full set brand new in the box. $525 for the full set.
