The lower beam is the lower cross bar on the Big Days Chase Rack System — the bike support bar that helps bikes ride supported and stable on the rack. Big Days sells it as a small part, which is exactly what you want when a beam has taken a hit in the parking lot, a rack is getting rebuilt after a hard season, or you'd rather keep a spare on the shelf than lose a race weekend to a bent bar.

On the standard rack, Big Days lists the lower cross bar at 52", with alloy cross bar construction per the brand's own rack specifications.

Features

  • Genuine Big Days small-parts component for the Chase Rack System
  • Serves as the rack's lower cross bar / bike support bar
  • Alloy cross bar construction, consistent with Big Days' rack specs
  • Sold individually — repair or rework a rack without replacing the whole system

Fitment goes by rack, not truck. This beam corresponds to the standard Chase Rack lower cross bar (52" per Big Days' rack specifications); if your system was configured for a shorter bed, measure your existing bar and confirm the length before ordering. To secure it, pair it with the Lower Bar Brackets, and find the rest of the replacement pieces in our rack accessories collection.

Specifications

  • Component: lower cross bar / bike support bar for the Chase Rack System
  • Length (standard rack spec): 52"
  • Material: alloy (per Big Days rack specifications)
  • Mounting: secures with Lower Bar Brackets, sold separately

Small Parts FAQs

What does the lower beam do on the Chase Rack System?

It's the rack's lower cross bar — the bike support bar that helps bicycles sit stable on the rack. Big Days lists the standard rack's lower cross bar at 52 inches with alloy construction, and sells this one individually under small parts for repairs and rack rebuilds.

Do I need anything else to install the lower beam?

The beam secures to the rack with Big Days Lower Bar Brackets, sold separately on our site. If you're replacing an existing beam, inspect your current brackets first — reuse them if they're still in good shape, or order a fresh set along with the bar.

Will the lower beam fit my rack?

It matches the lower cross bar on the standard Big Days Chase Rack System, which Big Days specs at 52 inches. Fitment goes by the rack, not the truck, so if your rack was configured for a shorter bed, measure your existing bar and confirm the length before ordering.
