Dynosty BTR 7.400" OE Replacement Pushrods for GM LS V8 — 5/16" Diameter, Set of 16 for Mild Low-Lift Cams

Dynosty BTR 7.400" OE replacement pushrods are a set of sixteen 5/16" diameter pushrods engineered as direct-fit stock replacements for GM LS-series Gen III/IV V8 engines used with mild, low-lift camshafts.

These pushrods from Brian Tooley Racing (BTR), sold under the Dynosty listing, give you a factory-length, drop-in option for common LS applications including 4.8, 5.3, 5.7, 6.0 and 6.2L variants. They are built to match OE dimensions and tolerances so you can restore valve-train geometry after wear, cam swap to a conservative profile, or repair a vehicle without changing pushrod length or diameter. Intended for mild, low-lift cams only, they provide a cost-effective way to maintain reliable rocker and lifter contact on Gen III and IV small-block V8s.

Which GM engines and model years are these pushrods compatible with?

These 7.400" BTR pushrods fit a broad range of LS family engines across Gen III and Gen IV small-block V8s. They are suitable for many factory blocks and common aftermarket conversions that retain OE pushrod length and 5/16" diameter requirements.

• Fits LS-series: 4.8L, 5.3L, 5.7L, 6.0L, 6.2L engines
• Covers popular codes: LS1, LS2, LS3, LS4, LS6, LSA, LQ4, LQ9, L92, L99, LC9
• Typical model years: 1997–2012 GM Gen III & IV applications
• Set includes 16 pushrods for complete V8 valve train replacement

Can I use these pushrods with a performance camshaft?

These are designed for stock or mild low-lift cam profiles only; they are not rated for high-lift, high-duration, or high-RPM race cams. Using them with aggressive cams can stress materials and change valve-train geometry, risking premature wear or failure.

• Recommended for mild cams like Truck Stage 2, Truck Norris, Chopacabra
• Not suitable for high-lift or race camshafts
• Maintain original rocker arm geometry and lifter contact when used as intended
• If upgrading to aggressive cams, consult matching performance pushrods

What are the physical specs and why do they matter?

Each pushrod measures 7.400" long with a 5/16" diameter—dimensions that match many OE assemblies. Proper length and diameter preserve valve timing and contact pattern, so staying with factory-equivalent parts helps prevent valve float, misalignment, and uneven wear.

• Length: 7.400" to maintain factory pushrod geometry
• Diameter: 5/16" for compatibility with common lifter/rocker interfaces
• Quantity: set of 16 for complete cylinder-bank replacement
• Manufacture: BTR (Brian Tooley Racing) OE-style construction for consistent tolerances

How should I choose pushrods for a rebuild or cam swap?

Match pushrod length and diameter to the lifters, rockers, and cam profile you plan to use. For conservative cam swaps and direct OE replacements, these BTR pushrods simplify installation because they replicate factory dimensions and require no additional measurement in most cases.

• Confirm engine block and head compatibility before ordering
• Use for repairs, restoration, or mild cam upgrades where OE length is retained
• Check rocker arm type—stock vs. aftermarket—to ensure fitment
• If unsure, measure current pushrod length and consult a technician

Who this is for: These Dynosty-branded BTR Brian Tooley Racing pushrods are aimed at owners and mechanics rebuilding or maintaining GM LS-series Gen III/IV small-block V8s who need a reliable, factory-length set for stock or mild low-lift cam profiles. Ideal for routine maintenance, restoring worn valve trains, or conservative cam swaps on trucks and street cars that run standard valve-train geometry.
