Another TurboKraft original.

TurboKraft’s Rocker Locks solve the problem of rocker shafts coming loose and shifting as the engine reaches operating temperature. 

When the rocker shafts move in the camshaft housing, they shift to the side so only one end is supported.  Not only does this create a huge oil leak, but the rocker arm is no longer completely supported and risks binding or breaking, causing a cascade of expensive engine component failures (rocker arms, timing chains and sprockets, valves, pistons…)

TurboKraft’s Rocker Locks and CNC machined of stainless steel so they will not corrode.   
Their design correctly positions the rocker shaft within the camshaft housing to provide the greatest support of the rocker arm.
 
They are machined to maintain the expansion (flaring) of original rocker shaft to create the oil seal to the housing, though Motorsports Rocker Shaft Seals are strongly recommended for all engines to minimize the risk of leaks.  (Motorsports Rocker Shaft Seals sold separately.)

-Installation is a direct bolt-in replacement for the original rocker shaft bushings and nuts.

-Easier to install than original parts – nut end locks into camshaft housing.

-Does not require removing the engine from the car, nor the removal of the chain boxes, or camshaft-driven components (power steering pump, scavenge pump, etc.)

Inexpensive insurance!  Costs to replace later can exceed 10.4 hours, plus gaskets, plus shop supplies, plus…

An essential upgrade for all racing engines and Turbos.
Fits all 911 engines 1965-1994
