Straub Engine Rocker Arm
Straub Technologies Engine Rocker Arms: Precision Valvetrain Engineering
When it comes to high-performance valvetrain components, Straub Technologies has earned a dedicated following among GM enthusiasts and engine builders who refuse to compromise on quality. Their lineup of engine rocker arms reflects a focused engineering philosophy: address the real-world failure points of OEM and generic aftermarket designs and eliminate them entirely.
LS-Series Rocker Arm Kits
Straub Technologies' most recognized rocker arm offerings are purpose-built for the GM LS platform. Their LS1 and LS3 rocker arm kits feature a 1.7 ratio and are constructed from investment cast steel that has been shot peened and micro polished to stress-relieve each individual part — a manufacturing step that significantly reduces the risk of fatigue cracking under high-RPM operation. Each rocker is fully assembled with a proven bushing kit featuring self-lubricating bronze material and a proprietary oiling system to the trunnion. Each kit comes complete with Grade 12.9 bolts and Straub's exclusive lifetime warranty against body breakage.
The Bronze Bushing Trunnion Advantage
One of Straub Tech's most celebrated innovations is their LS trunnion bushing upgrade system, which solves a well-known weakness in the OEM LS valvetrain. Engineered to provide maximum lubrication to the trunnion while also providing maximum load capabilities, the proprietary bushing material is fed with a full oiling channel that constantly supplies oil to the bushing surface. The greater surface area supports 300 times the load of a needle bearing, and eliminates the risk of needle bearings destroying the engine when using aggressive cam profiles with stock-type rockers. These trunnion kits are compatible with all LS1, LS2, and LS3 engines equipped with 1.7 rockers that use stands on the head.
Big Block Chevy & Small Block Chevy Coverage
Straub's rocker arm range extends well beyond the LS platform. Their BBC offering is a set of aluminum roller rocker arms produced in partnership with Harland Sharp, featuring a 1.7 ratio designed for use with OEM GM cylinder heads. For Small Block Chevy applications, Straub offers modified geometry rocker arms that go a step further than standard replacements: these Straub Tech-modified rockers are engineered to optimize roller-to-valve stem contact and sweep on aftermarket 23-degree SBC cylinder heads — including VEPR, AFR, Dart, Brodix, and Edelbrock castings — resulting in improved valvetrain geometry, reduced guide wear, and more consistent valve motion.
Stainless Steel LS1 Option
For builders looking to move away from OEM-style pedestal mounts entirely, Straub also offers a stainless steel LS1 rocker arm kit at a 1.7 ratio, designed to be used without the OEM rocker stand and including pushrod guides, rocker stud adapters, and poly locks — everything needed in a set of 16.
