The Rollmaster Gold series timing chain kit is manufactured to exacting standards using billet steel for both the crank and camshaft sprockets. This kit comes with 9-keyway crankshaft sprockets to allow more adjustment for dialling in the cam. Crankshaft sprocket keyways are in 2 degree increments always unless otherwise stated. The relationship from crank keyway to camshaft sprocket timing is 2:1 meaning that the amount of advance or retard at the camshaft is in one degree increments i.e. 1, 2, 3 or 4 degrees. Multiple keyways are a solid fixture and do not tend to move or work lose like offset dowels, thus providing a positive locking of the cam timing to the desired position.

Rollmaster timing chain kit is light weight but stronger than any other kit available due to the weight savings of billet steel and CNC machinery. Rolling resistance is also substantially decreased on the cam gear with the use of a Torrington thrust bearing. No additional machining is required to fit this kit and there is no need for offset bushings or drilling of cam gears. 

All Gold series timing chain kits feature a billet steel construction with nitrided sprockets for added strength and Rollmaster's own pro series Iwis full roller timing chain. This chain kit is ideal for high performance applications where the chain is exposed to constant shock loading and rapid acceleration/deceleration rates.

Contents:

• 1 X Double row timing chain
• 1 X 3 Bolt camshaft sprocket
• 1 X Crankshaft sprocket
• 1 X Oil pump drive
• 1 X Torrington bearing
• 2 X Oil pump spacer
• 4 X Bolt

This main cap girdle is designed to reduce "cap walk", stop block web flexing and eliminate cracking of the main caps/block webs; this is achieved by boxing in the main caps. Our light weight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage. The brace nearly doubles the main web support area in the engine.

In addition, due to the close proximity of the main stud girdle to the crankshaft and rods it also aids in stripping oil off of the crank, which in itself yields a net gain in HP.

Fabricated from 12.5mm thick 6061-T6 aluminium, these girdles are a must for high rpm/high horsepower applications where block rigidity is critical.

Contents:

• 1 X Alloy main girdle

Notes:

• This girdle fits all GM LS variants except for LS7 and LS9.
• This girdle is compatible with OEM windage tray, main caps and sump.
• This girdle will clear up to a 4" stroke.
