TSP H-Beam Rod and JE LS3 Boost Drop In Piston Combo – No Balance w/ LS3 Crank

TSP H-Beam Rod and JE LS3 Boost No-Balance Piston Combo – No Balance w/ LS3 Crank

This complete rotating assembly combo pairs Texas Speed Performance (TSP) Super H-Beam connecting rods with JE Performance LS3 pistons engineered specifically for boosted LS3 applications. The JE pistons are for the LS3 and require no balancing when used with our TSP H-Beam Rods and stock GM LS3 crank. Rod Bearings and File Fit Ringset are included — everything you need for a premium build with strength, reliability, and race-proven hardware.

Piston Specifications

• Application: JE LS3 Boost No-Balance Piston (designed for GM LS3)
• Bore: 4.065″
• Compression Height (CH): 1.300″
• Stroke: 3.622″
• Wrist Pin Diameter: .927″
• Dish Volume: -11cc Dish
• Included: Rod Bearings and File Fit Ringset

Technical Details

• Rod Material: Heat-treated & stress-relieved 4340 steel
• Rod Type: TSP Super H-Beam
• Rod Bolt: ARP L19 rod bolts included (maximum clamping force)
• Torque & Machining Process: Each rod is torqued and re-torqued during machining — initial torque and rough hone, disassembly to release residual stress, then final reassembly and hone to ensure roundness at installation
• Rated Power Capacity: Super H-Beam rods rated for upwards of 900 ft-lbs flywheel HP (engine build dependent)
• Balance Requirement: No balancing required when JE LS3 pistons are used with TSP H-Beam rods and a stock GM LS3 crank
• Notes on Blocks: Blocks utilizing piston oil squirters may require local clearancing.

Performance & Compatibility

This combo is ideal for LS3 builds where boosted performance and reliability are priorities. JE pistons’ no-balance claim simplifies rotating assembly work when combined with Texas Speed H-Beam rods and the stock GM LS3 crankshaft. The TSP rods’ manufacturing process and ARP L19 bolts provide strong, dependable clamping for high-boost, high-horsepower applications. Always verify clearances and installation dimensions before assembly.

Important Installation Notes

• Ring gaps, piston-to-wall clearances, and bearing clearances must be checked by the end user prior to final assembly to avoid engine damage.
• Verify piston-to-deck and piston-to-valve clearances for your specific head/gasket/rod combination.
• If your block has oil squirters, check for adequate clearance around the piston skirts and apply clearancing procedures if needed.
• Use only recommended assembly lubricants and torque sequences for ARP L19 rod bolts; follow ARP and TSP torque specs.
