• 1991-2001 Nissan Sentra (SR20DE, FWD)
• 1991-1994 Nissan NX2000 (SR20DE, FWD)
• 1989-2002 Nissan Bluebird U12 / U13 / U14 (SR20DE, SR20DET, FWD/AWD)
• 1990-2002 Nissan Pulsar GTI-R N14 / N15 (SR20DET, AWD)
• 1990-2001 Nissan Primera P10 / P11 (SR20DE, FWD)
• 1991-2001 Infiniti G20 P10 / P11 (SR20DE, FWD)
• 1995-2002 Nissan Avenir (SR20DE, SR20DET)

Fitment Notes

• Fits Nissan SR20DE and SR20DET engines with 17mm rod pin diameter only
• +0.25mm oversize - for use with crankshafts reground -.010" (0.25mm) undersize; crankshaft machining is required before installation
• RWD SR20DET (S13/S14/S15 Silvia, 180SX) and FWD/AWD SR20DE/SR20DET (Bluebird, Pulsar, Sentra, Primera) share the same rod journal specs and use this bearing
• SR20VE and SR20VET applications: verify rod journal diameter independently before ordering
• 240SX is a swap application only - stock 240SX uses KA24DE; confirm SR swap before ordering
• Always confirm crankshaft undersize with your engine builder before purchasing

Features

• pMax Black tri-metal overlay is 24% harder than conventional race bearings via a proprietary nano-scale molecular hardening process
• Intermediate load capacity of 17,000 psi and overlay load capacity of 10,200 psi for sustained high-boost, high-RPM applications
• XP-series narrowed profile on the crank cheek side eliminates dangerous fillet ride on high-radius aftermarket crankshafts
• SecureBond adhesion bonds all tri-metal layers for superior structural integrity under extreme performance loads
• Wall thickness tolerance held to ±0.0001" - up to 2.5x tighter than competitor standards - for consistent shell-to-shell fitment
• Increased crush height improves bearing-to-bore contact and reduces spin potential at high RPM
• One-set fitment design eliminates the need for multiple sets to dial in desired oil clearance

Product Description

The King CR4136XP0.25 is a +0.25mm oversize XP-series connecting rod bearing set engineered for Nissan SR20DE and SR20DET 2.0L four-cylinder engines. Sized for crankshafts that have been reground to a -.010" (0.25mm) undersize, these bearings are the correct choice when the crank has been machined to restore a proper bearing surface after wear or damage. Built with King's pMax Black tri-metal construction, they deliver a 24% harder overlay and load capacity up to 17,000 psi in the intermediate layer - making them well-suited for turbocharged SR20DET builds in S13, S14, and S15 platforms running elevated boost and forged rotating assemblies.

The XP geometric features - including a narrowed crank cheek profile and increased crush height - reduce fillet ride risk on aftermarket crankshafts and improve bearing-to-bore contact for better heat transfer and reduced spin potential at high RPM. Wall thickness is held to an industry-leading ±0.0001", ensuring shell-to-shell consistency that minimizes selective fitting during assembly. These bearings are equally applicable to FWD SR20DE platforms such as the Sentra, Primera, and Infiniti G20. Crankshaft machining to -.010" undersize is required prior to installation - always confirm sizing with your engine builder before ordering.
