*GMH OEM ROCKER ARM FAILURES* Motoring (2017) reported “Holden will repair the 6.2-litre LS3 engine in the final 2000 or so V8 Commodores built this year following reports of engine noise and even failure in cars with as little as 50km on the clock”. The problem has been traced to a faulty batch of inlet rocker arms causing rough idle or misfiring of the engine. Rocker arms have fractured at the nose in some instances; wreaking havoc on the valve and cylinder. Take the bull by the horns and upgrade from your already wear inducing solid/non-roller tip OEM rockers. Our 8mm Ultralite Pro design can be fitted in ~1 hour and at a fraction of the cost of major rebuilds associated with faulty OEM rocker arm failure. No machining required, fits under standard rocker covers. Steer clear of cheap “fix” trunnion upgrades, which fail to address the shortcomings of OEM rocker arms. fit Yella Terra with confidence - Track Tested. Street Proven. By concentrating more mass at the fulcrum, the Ultralite Pro can withstand a much heavier spring than the Ultralite without compromising any oscillating weight. 10mm bolt down versions are available, in addition to the factory 8mm easyfit (EF). Intended for those who need lightweight rocker arms but insist on heavier springs!
