A must have when boosting up your LSA!

The supercharger coupler plays a vital role in maintaining drive between the supercharger pulley and the rotor-pack. Located in the snout of the blower, the original coupler contains a spring mechanism and is notorious for rattling at idle or part throttle when subjected to an increase in boost or high load applications. If these symptoms are ignored, the supercharger shaft can eventually wear down; creating debris that will cause the shaft seal to fail or worst case have the rotor-pack seize. 

Our heavy duty coupler is designed to handle the extreme stresses and loads of a boosted LSA while still maintaining factory drive-ability characteristics. It is manufactured from a high-grade thermoplastic material for increased performance and durability. Installation is quite simple, only requiring the removal of the snout then directly replacing the standard coupler.

Vehicle Fitment Guide

Note: This coupler is an ideal upgrade with our Dayco overdrive balancer kits, which can purchased through other listings.

These Mace rocker bolts suit HSV vehicles fitted with LS1, LS2, LS3 and LSA 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 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.

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!
