Dynosty OE-Style Pushrods for GM LS Engines 7.400" 16pc Set — 5/16" Diameter, Mild Cam Replacement

Dynosty BTR Brian Tooley Racing 7.400" OE replacement pushrods are a 16-piece set built to restore valve actuation on GM LS-series engines with mild, low-lift camshafts.

If your Gen III or Gen IV LS V8 (4.8, 5.3, 5.7, 6.0, 6.2 L) is due for fresh valvetrain components, these OE-style pushrods are a direct-fit option that matches factory geometry and diameter. They’re manufactured to the dimensions used by Brian Tooley Racing for stock-replacement and mild performance cams, making them a straightforward swap when maintaining rideability and valve timing accuracy.

What engine families and models will these pushrods fit?

These pushrods are specified for a wide range of GM small-block LS engines across both Gen III and Gen IV platforms. They suit applications where factory pushrod length and wall thickness are required for correct valve train geometry.

• Compatible with LS series: LS1, LS2, LS3, LS4, LS6, LSA and variants.
• Fits blocks and replacements: LQ4, LQ9, L92, L99, LM7, LC9 and others.
• Designed for 1997–2012 GM Gen III/IV small-block V8 engines.
• Ideal when retaining stock rocker ratios and lifter specifications.

How are these pushrods sized and what hardware specs matter?

Each pushrod measures 7.400 inches long with a 5/16-inch outside diameter, matching common OE replacements for LS engines. These dimensions maintain factory valve timing and rocker geometry when used with stock or mild cam profiles.

• Length: 7.400" (critical for correct valve lift and timing).
• Diameter: 5/16" for compatibility with standard lifter and rocker bores.
• Supplied as a full set of 16 to cover both banks of a V8 engine.
• Intended for use with recommended low-lift camshaft designs only.

Which camshaft types are appropriate for these pushrods?

These pushrods are optimized for mild, low-lift camshafts where OE-style stiffness and length are required. They are not designed for high-lift or race-level cams that demand heavier construction or altered geometry.

• Suitable for mild aftermarket cams such as Truck Stage 2 and similar profiles.
• Works well with conservative performance upgrades that keep near-stock lift and duration.
• Not recommended for extreme competition cams or high-lift conversions.
• Use when restoring factory valve motion after wear or failure.

How does installation and maintenance look for these pushrods?

Installation follows standard pushrod replacement procedures and should be performed with proper valve train indexing and torque specifications. Regular checks for straightness and wear will prolong service life and preserve valvetrain function.

• Replace as a complete set of 16 to ensure balanced operation across the engine.
• Inspect for bends, scoring, or wall thinning before installation.
• Verify pushrod length using a dial indicator and checking rocker preload at install.
• Keep rocker and lifter hardware within manufacturer tolerances for best results.

Who is this for: These Dynosty BTR Brian Tooley Racing 7.400" pushrods are aimed at owners and technicians restoring or maintaining GM LS-series V8 engines that retain near-stock valvetrain geometry. If you run a daily-driven or lightly modified truck or car with a low-lift cam and want an OE-dimension replacement, this 16-piece set provides the correct length, diameter, and fitment to get your engine back to reliable operation without altering valve timing or rocker ratios.
