Description
Eliminate valvetrain instability, resist high-RPM lifter pump-up, and maximize horsepower in aggressive V10 builds with the Johnson Lifters Gen 1–3 Viper Reduced Travel Tie-Bar Hydraulic Roller Lifters (Part # 2313V10R / SDPC Part # JLC2313V10R). Sourced and manufactured 100% in the USA from premium aerospace-grade alloy steel, this race-series lifter set delivers the ultra-precise valvetrain control of a solid roller while maintaining the quiet operation and low maintenance of a hydraulic design.
Engineered specifically for the unique demands of 1992–2006 8.0L and 8.3L V10 powerplants, the 2313V10R features Johnson’s proprietary Reduced Travel (.093 in.) internal valving and precision high-flow disc check valves. This design significantly limits internal oil volume and plunger deflection under elevated valve spring pressures and aggressive ramp rates. Coupled with heavy-duty vertical link bars and continuous pressure-fed axle oiling to the needle roller bearings, these lifters provide race-proven durability across high-boost, road-race, and max-effort street applications.

Engine Compatibility & Fitment
- Supported Vehicle Applications:
- 1992–1995 Dodge Viper RT/10 (Gen 1 8.0L V10)
- 1996–2002 Dodge Viper GTS & RT/10 (Gen 2 8.0L V10)
- 2003–2006 Dodge Viper SRT-10 Roadster & Coupe (Gen 3 8.3L V10)
- 2004–2006 Dodge RAM SRT-10 Regular Cab & Quad Cab (8.3L V10)
- Application Scope: Direct fitment for factory OEM and aftermarket Gen 1–3 V10 blocks (not intended for Gen 4 or Gen 5 variable cam timing V10 engines).
- Power Adder Ready: Specially built to withstand high spring seat pressures and sustained RPM in twin-turbo, supercharged, road-racing, and standing-mile race applications.
Installation Guidelines & Preload Protocol
- Recommended Preload: Set cold lifter preload to .035 in. (+/- .010 in.) from zero lash. For aluminum cylinder blocks, target the deeper side of the window (.040–.045 in.) to compensate for thermal engine block expansion at operating temperature.
- Measure Pushrod Length: Always measure pushrod length with an adjustable checker on both intake and exhaust valves during dry assembly. Aftermarket camshaft base circles, cylinder head decking, and valve job heights alter required pushrod length.
- Valley & Bore Clearance: Test-fit the link-bar pairs throughout complete 360-degree camshaft rotation to verify link bars clear the lifter valley casting and cylinder barrel edges.
- Assembly Lubrication: Generously coat lifter bodies, link bars, and roller wheels with quality high-pressure engine assembly lube. Do not pre-pump lifters with oil prior to setting preload to avoid false zero-lash readings.
