Twin Power 99 -Up Big Twin Exc 99 Softail 00-Up XL Lifters Slow Bleed Type High Performance 4 Pk

This set includes four Twin Power slow bleed lifters, designed for high-performance applications on a wide range of Harley-Davidson motorcycles. These lifters feature a steel body and a slow leak-down characteristic, meaning they act much like solid lifters. This allows them to maintain full cam lift across all RPMs, which can open up a higher RPM range and support more aggressive valve spring pressures. This makes them a solid option for riders looking to get more out of their engine's performance.

The slow bleed design is key here; it ensures consistent operation and helps maintain optimal valve timing even when you're pushing the engine hard. This is particularly beneficial for modified engines or those built for higher performance. The steel body construction contributes to their durability and reliable operation within the engine. These lifters are sold in a set of four, providing everything you need for a complete engine build or upgrade on many popular Big Twin and XL models, including bikes like the Harley-Davidson Road King, Street Glide, and Sportster XL.
