BST BSSP Adjustable Chrome Pushrod & Cover Kit for Harley Twin Cam 1999–2017 — Direct-Fit, Corrosion-Resistant

This complete kit includes all components needed to swap out the upper and lower pushrod tubes, adjustable pushrods and covers for Twin Cam engines that use adjustable pushrods. Finished in chrome-plated aluminum for rust resistance and visual appeal, the set is designed for direct-fit installation without removing rocker boxes or coolant lines on compatible Harley-Davidson Twin Cam setups.

How do these pushrods and covers fit my 1999–2017 Twin Cam?

The kit is manufactured to match the dimensions and mounting requirements of Twin Cam engines that accept adjustable pushrods. It specifically excludes 2017 Touring applications; other 1999–2017 models using adjustable pushrods are compatible. Verify your engine uses adjustable pushrods before ordering.

• Designed for Twin Cam engines (1999–2017) with adjustable pushrods
• Excludes 2017 Touring models—check model specifics
• Direct-fit parts intended to match stock mounting points
• Includes all pieces for a full four-cylinder pushrod assembly replacement

What parts are included and what materials are used?

This set supplies a full complement of upper and lower tubes, adjustable pushrods, springs, O-rings and related hardware to complete a four-pushrod replacement. Components are aluminum with a chrome-plated finish to resist corrosion while keeping weight low.

• 4 upper tubes and 4 bottom cover tubes for each cylinder location
• 4 adjustable pushrods, 4 springs, 4 upper clips, 4 washers
• 12 replacement O-rings included for tube seals
• Chrome-plated aluminum construction for durability and lighter weight

How difficult is installation and will I need to remove rocker boxes?

The design allows installation and removal without taking off rocker boxes or disconnecting coolant lines on compatible Twin Cam engines. That reduces labor and simplifies routine maintenance or upgrades, but a basic understanding of pushrod length and engine timing is recommended.

• Installable without dismantling rocker boxes or coolant plumbing on compatible engines
• Includes all necessary tubes and sealing O-rings for straightforward replacement
• Adjustable pushrods allow fine-length tuning at the cylinder head
• Professional or experienced DIY installation recommended for precise adjustment

Will chrome plating affect fit or function?

The chrome finish is cosmetic and protective; it does not change the intended fit when components match the engine specification. The aluminum core keeps parts light while the plating offers a rust-resistant surface; ensure surfaces are clean and torqued to specification during assembly.

• Chrome plating applied over aluminum base for corrosion resistance
• Maintains original fit when paired with correct engine models
• Clean mating surfaces and follow torque specs to ensure sealing
• Periodic inspection preserves finish and sealing performance

Who is this for: Riders and mechanics upgrading or restoring Twin Cam-equipped Harleys from 1999 through 2017 (non-2017 Touring) who want a full, chrome-finished pushrod and cover kit that includes adjustable pushrods, all tubes and seals for a complete four-cylinder replacement. It’s aimed at people who need a complete hardware set for accurate pushrod length adjustment and a corrosion-resistant visual upgrade, and who are comfortable performing or overseeing engine valve train work.
