Body-Solid GAP1 Aluminum Pulley Upgrade Kit for G1S

All-aluminum, sealed-bearing pulley set to replace stock nylon pulleys on Body-Solid G1-series home gyms

Give your G1-series home gym a pro-level feel with the Body-Solid GAP1 Aluminum Pulley Upgrade Kit. This complete set swaps out the factory nylon pulleys for solid aluminum units with sealed bearings—producing smoother cable travel, crisper response, and a premium, long-lasting look.

Designed for straightforward, one-for-one replacement, the GAP1 kit uses your gym’s existing 3/8″ pulley bolts and keeps original cable routing intact. The result? Faster, quieter reps and a sleek upgrade that instantly elevates your G1, G1B, or G1S.

  • Compatible Models: G1, G1B, and G1S

Body-Solid GAP1 Key Features

Sealed-Bearing Performance

Each pulley spins on sealed bearings to reduce friction and noise while improving cable tracking through full ROM.

Solid Aluminum Build

Durable, rigid pulleys hold shape under tension for reliable alignment and smooth feel over time.

One-for-One Replacement

Directly replaces the original nylon pulleys—no cable length changes or special mods needed.

Stable Cable Path

True, concentric machining helps maintain consistent cable angle for better feel and wear resistance.

Clean Aesthetic Upgrade

Aluminum finish adds a professional look that pairs nicely with black or silver G-series frames.
