ROLLER ROCKERS

* INCREASE HORSEPOWER * REDUCE FRICTION * REDUCE WEAR   

Roller Rocker Assembly
    • Stock TR6 rockers have a chronic problem of wear and galling on the shaft. Good Parts premium roller rockers have needle bearings riding on a hard shaft to reduce friction and eliminate wear at this critical area. A needle bearing roller at the tip freely rolls over the end of the valve stem to reduce side load and wear of the stem and guide. Oil channels lubricate the roller and adjuster ball. The rockers are precisely machined from super strong 7075T6 aluminum and anodized a golden color.
    • Good Parts TR6 roller rocker assemblies now include heavy duty, shaft clamping pedestals machined from solid 6061T6 aluminum. These pedestals are also available separately. They will work with stock rockers but please note that the stock rockers will require slight modification to fit in the end pedestals.
    • Stock TR6 rockers are 1.46:1 ratio. Good Parts offers roller rockers in 1.55:1 or 1.65:1 ratio. Increasing the rocker ratio improves engine performance by opening the valves faster and further. The combined benefits of reduced friction and improved airflow can increase horsepower by as much as 10%.
    • The installation of cam bearings is recommended in TR6 engines using 1.65:1 ratio rockers with high performance valve springs.

      ***NOTE: TR2-4 rockers do not fit under the original rocker cover. An after-market aluminum rocker cover or a spacer is required.
  • Installation of high ratio rockers will increase your net valve lift. Check your valve spring capacity before installation. For best cam life, keep valve spring pressures as low as possible but strong enough to avoid valve float.

These billet aluminum pedestals provide better shaft support to prevent shaft breakage.  The shaft is clamped tightly in place when the mounting hold-down nuts are tightened.  The end wing supports and clamps the end of the shaft.  These pedestals position the shaft at the same height as the original pedestals.

These billet aluminum pedestals provide better shaft support to prevent shaft breakage.  The shaft is clamped tightly in place when the mounting hold-down nuts are tightened.  The end wing supports and clamps the end of the shaft.  These pedestals position the shaft about .080" higher than the original pedestals for better gometry when used with Good Parts roller rockers.

This rocker shaft is made of the same high quality, case hardened material as Good Parts roller rocker shafts but it has the OE oil hole configuration for stock or bushed rockers. Not recommended for needle bearing rockers due to the location of the oil holes and notches.

Do not confuse these shafts with a nitrided shaft.  Nitriding hardens the surface of a softer material to a very shallow depth.  Good Parts shafts are case hardened to RC60 minimum to a depth of .040" minimum.

US $149.00

Hardened, smooth ball. Adjusts with hex wrench. Replaces stock early (short) or later (long) adjuster.
