Uprated Rocker Gear

All cars can benefit from a replacement tuftrided rocker shaft, they will resist wear and breakage especially when using high revs. The friction and the rocker side loads normally associated with the standard rocker gear can be reduced and the location made more positive, by fitting the three piece steel spacer set instead of the standard shaft springs. Higher ratio rocker assemblies in steel are available taking the ratio from 1.245:1 to 1.5:1 and also the alloy roller tipped versions. The roller rocker version increases the ratio to 1.5:1 and is also available at 1.3 and 1.7 to special order. The roller tips reduce the side loads on the valve stems and associated wear. The higher ratio is ideal for increasing the valve lift and improving the torque and is best combined with a suitable camshaft.
