These Mace rocker bolts suit Holden vehicles fitted with LS1, L76, L77, L98 and LS3 5.7L, 6.0L and 6.2L 8 cylinder engines. These are a great alternative to the torque to yield factory rocker arm bolts and won't require to be replaced ever again.

These bolts should be torqued to 23ft/lbs and suit both factory and Mace aftermarket rockers.

This OTR cold air intake ulitises an OEM style plastic construction which makes it exceptionally durable while giving a factory style look to your engine bay. In conjunction to the larger filter area where airflow is dramatically increased from standard, there are also port bosses designed into both sides, allowing breather and/or catch cans setups to be easily plumbed into the OTR.

Installation of this OTR air intake is extremely easy with the adjustable mounting brackets and even clears Monaro's fluted bonnets!!

With MAF or MAF-Less configurations available, the new plastic VCM OTR covers all options.

Notes:

• The image is for illustrative purposes only.
• Vehicles with aftermarket radiators may experience installation difficulty. We will not be held responsible if your vehicle has an aftermarket radiator and fitment is unsatisfactory. Please check prior to purchase.
• A hole needs to be drilled in the OTR for the rubber grommet.
• Some modifications to the cooling/air-con system may be required on your VT-VX.
• MAF-Less configurations on some vehicles may require an additional IAT sensor and appropriate harness. These components have to be purchased separately.
• Please read the terms & conditions before making a purchase.
• For VZ MAF-Less OTRs, MAF-Less conversion kit (IAT sensor and harness) is mandatory and can be purchased through another listing.
• The MAFLess OTR requires a suitable tune. Depending on the current mods of the vehicle, we can supply a custom mail order tune separately, otherwise a dyno tune would be required.

This Mace exhaust manifold gasket set, for the popular GM LS engines, features OE quality multi-layer steel (MLS) construction to ensure a positive seal under extreme temperatures. These gaskets are designed to meet and exceed OEM specifications so you can be assured of quality and durability.

Three layers of stainless steel are utlilized in manufacturing of these gaskets and each layer has an embossment at critical sealing areas for maximum sealing. The spring steel layers provide tension when compressed, keeping the joint tight and preventing the seal from being blown out.

This Mace Torque-Lock limited slip differential (LSD) uses a sophisticated design to provide a quiet, automatic splitting of torque. It performs like an open differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant.

The advantage of the limited-slip differential design is apparent when comparing it to the standard or "open" diff. In vehicles with this older style of diff when one wheel began to slip or lose contact with the ground the slipping or non-contacting wheel would still receive the majority of the power whilst the contacting wheel remains stationary with the ground.

This issue is completely resolved with the Torque-Lock LSD. Harnessing a similar configuration to the Harrop and Eaton Truetracs, the automatic torque biasing design makes it the perfect limited slip differential upgrade for any enthusiast that will be using their vehicle for either straight-line drag, circuit, off-road or tough street work.

The proven helical gear technology found in the Torque-Lock LSD eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its durability, but its smooth and quiet operation as well. The low cost and effective operation all make the Mace limited slip differential the ideal choice for performance vehicles.

• The image is for illustrative purposes only.
• The M80 is a 3 bolts flange and the M78 is a 4 bolts flange.
• This Torque-Lock LSD does not suit VT Series I with M78 differential.
• This Torque-Lock LSD suits V8 engines only.

If you're looking at upgrading the performance of your vehicle without venturing into engine tear downs or expensive tuning packages, then you can't go past our upgraded differential gear sets. Focused on retaining an appetising affordability to performance ratio, installing a shorter differential ratio is probably one of the most noticeable performance modifications you can do without compromising driveability and compliance. 

Our Mace differential gear sets have undergone an extensive manufacturing process to ensure OEM-like fitment and durability in any application. The superior finish provides a more consistent, higher quality product as proven in our very own cars!

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
• 4 X Washer

Notes:

• The image is for illustrative purposes only.
• Red series chain kits for standard upgrades can be purchased through other listings. 
• Timing cover will require minor linishing to allow extra clearance for double row timing chains.
• Double row timing chains are not recommended with high volume oil pumps due to clearance issues.

Mace timing chain sets are designed for use with stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. This timing kit includes a stock replacement crank sprocket with a single keyway.

Contents:

• 1 X 3-bolt single trigger cam sprocket
• 1 X Single keyway crank sprocket
