Solid Roller Lifters - BBM Verticle Style

The HOWARDS RACING COMPONENTS Solid Roller Lifters in BBM Vertical Style (Part #91727) are purpose-built mechanical roller lifters engineered for Mopar B and RB-Series engines, including the legendary 426 Hemi. This complete set of 16 lifters delivers the precision valve actuation required for high-rpm competition builds, drag racing, and street performance applications where reliability under extreme conditions is non-negotiable.

Featuring a 0.904-inch outer diameter and link-bar design, these solid roller lifters eliminate the wear and compliance issues inherent in flat-tappet hydraulic designs. The roller design reduces friction at the camshaft interface while the solid construction provides consistent, predictable valve timing across the entire powerband—critical for carburetor jetting, ignition timing, and overall engine tuning on the dyno. The vertical orientation ensures proper oil distribution and eliminates the parasitic drag that can rob horsepower in competitive engines. Built to the exacting standards HOWARDS RACING COMPONENTS is known for, these lifters are manufactured to work seamlessly with compatible cam profiles and rocker arm assemblies.

These lifters are the go-to choice for serious Mopar engine builders, bracket racers, and hot rodders rebuilding or upgrading classic muscle car powerplants. Whether you're assembling a fresh block for a 1970 Road Runner, a 1971 Dodge Charger R/T, or any platform running B or RB-Series architecture, this complete 16-piece set simplifies sourcing and guarantees matched hydraulic characteristics across all cylinders. Proper lifter selection directly impacts cam longevity, valve control, and the ability to reliably support higher compression ratios and aggressive fuel mixtures.

Roller lifter technology has been the performance standard for decades, eliminating the need for frequent cam and lifter replacement cycles. The solid construction resists the wear patterns that degrade hydraulic units, making these a proven upgrade path for any serious Mopar build where longevity and consistent performance matter.
