Dynosty BTR V2 LS Premium Rocker Arm Trunnion Kit | LS1-LS6 4.8-6.2 | TK002

Boost LS rocker durability with the Dynosty BTR V2 Trunnion Kit

Engineered for the LS family, the Dynosty BTR V2 Trunnion Kit brings upgraded bearings, smarter lubrication, and a robust design to rocker arm assemblies. The result is a smoother rotation and a steady supply of lubrication where it’s most needed, helping you push harder without compromising reliability. This kit blends precision machining with durable materials to support high-load lifter conditions and spirited driving.

What sets the V2 apart is a pre-installed inner race bearing system crafted from 52100 heat-treated bearing steel. This pressed inner race design outperforms typical hardened steel in demanding environments, providing consistent performance under abuse and many miles of service. A self-oiling axle with priority feeding to the trunnion helps maintain lubrication where it matters most, minimizing friction and helping maintain steadier rocker operation across RPM ranges.

Key upgrades and fitment

• Pre-installed inner race bearings on the trunnion surface for quick, reliable assembly.
• 52100 heat-treated bearing steel for improved wear resistance compared to common alternatives.
• Self-oiling axle with priority feeding to the trunnion to support consistent lubrication.
• Includes: BTR V2 Trunnions, Caged Roller Bearings, LS Trunnion Clips, and LS Trunnion Install Washers.

Compatibility and usage notes

• Fits: LS1, LS2, LS3, LS6, L99, LS4, LS9 and related LS rocker configurations, including various truck style LS engines.
• Note: The trunnion may contact the passenger side valve cover baffle on early style LS1/LS6 covers. Verify clearance prior to installation.

What’s included and why it matters

• BTR V2 Trunnions for robust support.
• Caged roller bearings for smooth, consistent rotation.
• LS rocker clips to secure alignment during operation.
• LS trunnion install washers to ensure proper preload and fitment.

Whether you’re upgrading a high-mileage setup or building a performance-focused LS engine, the V2 kit offers a balanced blend of durability, precision, and practical design. It presents potential benefits such as reduced play, smoother rocker motion, and reliable lubrication under load—without asserting guaranteed results. Evaluate the kit against your specific build and driving goals to determine if it aligns with your plan.
