Dynosty BTR V2 Trunnion Kit for LS-Series Rocker Arms — 52100 Bearings, Self-Oiling Axle

The Dynosty BTR V2 Trunnion Kit is a heavy-duty replacement trunnion assembly designed to upgrade LS-series rocker arms with pressed 52100 inner-race bearings and a self-oiling axle for improved durability and oiling.

If you run an LS-family small-block (LS1, LS3, LS6 and many truck variants) and you want a more robust rocker trunnion solution, this kit swaps into Brian Tooley Racing V2-style rockers to reduce wear and improve bearing life. The V2 upgrade replaces earlier materials and addresses lubrication routing with priority feed to the trunnion, and it ships with all hardware needed for installation: caged roller bearings, clips and install washers.

Will this trunnion kit fit my LS engine and rocker style?

Yes — the Dynosty BTR V2 Trunnion Kit is built for a wide range of LS-family engines and for BTR V2 style rocker arms. It fits early and later LS small-blocks used in cars and trucks, but verify clearance where valve cover baffles differ.

• Compatible with LS1, LS2, LS3, LS6 and many truck LS variants (LQ4, LQ9, LM7, etc.).
• Designed for Brian Tooley Racing V2 rocker arm style.
• Note: early LS1/LS6 passenger-side valve cover baffles may interfere—check fitment.

How does the V2 design improve durability compared with V1 parts?

The V2 trunnion uses a pressed inner race made from 52100 heat-treated bearing steel, which offers superior fatigue resistance compared with the 8620 carburized steel used previously. That stronger inner race, plus caged roller bearings and a self-oiling axle, reduces wear at the rocker pivot under heavy loads.

• Pressed 52100 inner-race bearing steel for higher load capacity.
• Caged roller bearings included to minimize friction and wear.
• Self-oiling axle with priority feed delivers consistent lubrication to the trunnion.

What comes in the kit and what do I need for installation?

The kit is supplied as a complete trunnion service pack so you won’t need to source uncommon parts separately. It includes the BTR V2 trunnions, caged roller bearings, retention clips and install washers. Basic mechanical skills and common engine tools are required for removal of rockers and trunnion installation; assembly should be performed with clean oil and correct torque specs.

• Included: BTR V2 trunnions, caged roller bearings, trunnion clips, install washers.
• Tools typically needed: rocker arm removal tools, torque wrench, clean engine oil, common sockets.
• Check valve cover clearance on early LS1/LS6 passenger side before final assembly.

What performance or maintenance benefits can I expect?

While not a power-adding part, the BTR V2 trunnions are intended to prolong rocker pivot life and improve reliability under high RPM or high-load use. Better materials and lubrication reduce the chance of accelerated wear, meaning fewer service intervals and a more consistent valvetrain feel over time.

• Longer bearing life and greater resistance to fatigue than many factory trunnions.
• Improved lubrication to the pivot lowers friction and heat-related wear.
• Reduces the likelihood of rocker-related failures during performance driving.

Who is this for: The Dynosty BTR V2 Trunnion Kit is aimed at LS owners, builders and performance enthusiasts who use Brian Tooley Racing V2-style rockers and want a stronger, better-oiled pivot solution. It's especially suited to high-RPM engines, track cars, and any build where extended valvetrain durability is a priority; novices can install it but should confirm valve-cover clearance and follow torque instructions or consult a professional.
