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.
