TSP H-Beam Rod and JE L8T No-Balance Piston Combo - No Balance w/ L8T Crank

Complete rotating assembly pairing Texas Speed Performance (TSP) Super H-Beam connecting rods with JE Performance pistons designed for the 6.6L L8T. The JE pistons are for the 6.6 L8T and require no balancing when used with our TSP H-Beam Rods and stock L8T crank. Rod bearings and a file-fit ringset are included — built for strength, reliability, and high-performance applications.

Technical Details

Rod Material: Heat-treated & stress-relieved 4340 steel
Rod Type: TSP Super H-Beam
Rod Bolts: ARP L19 rod bolts included for maximum clamping force
Manufacturing Process: Rods are torqued, rough-honed, separated to release residual stress, then reassembled and final-honed to ensure true roundness at installation
Power Rating: Super H-Beam rods rated for builds up to ~900 flywheel HP (engine & build dependent)
Balance Requirement: No balancing required when JE L8T pistons are used with TSP H-Beam rods and a stock L8T crank
Oil Squirter Note: Once installed, oil squirter clearance must be checked and adjusted accordingly

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 head/gasket/rod combination.
If your block uses piston oil squirters, check and modify clearance around the piston skirts as required.
Follow ARP and TSP torque specs and use recommended assembly lubricants and torque sequences for ARP L19 rod bolts.

Important Note: Ring gaps, piston-to-wall clearances, and bearing clearances have to be checked by the end user to avoid engine damage.
