MACE PERFORMANCE VALVE SPRING KIT TO SUIT HOLDEN COLORADO RC ALLOYTEC LCA 3.6L V6

This heavy duty performance valve spring kit suits all Alloytec and SIDI V6 engines. It is built for high revving and boosted builds and is a perfect match for our Mace camshafts. Best of all it is a straight drop in upgrade, with no machining or modification to the cylinder heads, and it reuses your standard valve stem seals.

Ovate Wire Spring and Titanium Retainer Kit: SPG611

The kit pairs an ovate wire spring with a tough gas nitride treated finish and lightweight titanium retainers. The lighter retainers take weight out of the valvetrain so the valves keep following the cam cleanly at high RPM, helping to hold off valve float and keep the engine pulling strongly right up top.

Specifications:

• 85 lbs seat (installed) pressure
• 235 lbs at 0.500 inch valve lift
• Ovate wire with gas nitride treatment
• Lightweight titanium retainers included
• Drop in fitment, no machining, uses standard valve stem seals
