Ultra-Gold™ ARC Rockers, LS1/LS6/LS2, 4.8/5.3/6.0L, 1.72:1

Available as an individual rocker or a set.

  • 19024-1 ~ Individual rocker 1.72 Ratio, Non-Adjustable Rocker. 
  • 19024-16 ~ Full Set of (16) 1.72 Ratio, Non-Adjustable Rockers w/ Bolts & Mounts. 

Non-adjustable, bolt-on, Ultra-Gold™ ARC Series Aluminium Rockers are more durable than both stock rockers and other aftermarket aluminium rocker designs. A CNC-extruded body provides increased strength and stiffness, which is especially important for higher-load springs. The roller tip meanwhile is an upgrade over the stock slider, which is not meant for use with high-lift cams and springs that see increased load. What’s more, a larger-than-stock billet trunnion package features captured needle bearings to help prevent failure. These pedestal-mount rocker arms are offered in 1.72 and 1.82 ratios, with the 1.82 option providing a convenient way of increasing valve lift without having to undergo a full cam swap. The rockers include pedestal mounts and bolts, and just like the OEM LS rockers, are a non-adjustable, bolt-down design. Aftermarket valve covers, valve cover spacers, or valve cover clearancing may be required.

  • Large billet trunnion w/ captured needle bearings help prevent rocker failure

  • CNC-extruded body is much stiffer & stronger than competing aftermarket aluminium rockers

  • Designed for LS1, LS2, LS6 & LS-based truck applications (4.8/5.3/6.0L)*

  • Roller tip is an upgrade over stock slider tip & reduces friction

*Will not work with 2014+ L83 Direct Injection / VVT 5.3L or 2007+ 6.0L engines with rectangle port heads.
