Boat Lift Parts & Replacement Essentials: Keeping Your Lift in Peak Condition

There’s no faster way to spoil a day on the water than discovering your boat lift isn’t working. A simple routine of inspections and high‑quality marine‑grade hardware keeps everything running smoothly. At Monster Bolts, you’ll find everything from drive‑pipe cable‑attachment bolts to our new 316 stainless axle‑bolt kits with zerk fittings—all engineered for salt, sun, and heavy loads.

Routine Maintenance: Your First Line of Defense

Set a monthly or seasonal checklist to tighten hardware, grease fittings, and watch for cable wear. Catching small issues early prevents costly downtime later.

• Lubrication: Grease all pulleys and axle‑bolt kits with zerk fittings.
• Hardware Check: Re‑torque nuts and bolts after severe weather or heavy use.
• Cable Inspection: Replace immediately if you spot fraying or corrosion.

Essential Boat‑Lift Parts & When to Replace Them

Your lift relies on several critical components. Knowing when to swap them keeps your boat (and peace of mind) secure.

Sheaves & Pulleys

A worn sheave adds friction and shreds cable. Our lightweight 4" × 3/4" aluminum sheave with an Oilite bronze bushing spins freely and resists corrosion. Replace if you see cracks, flat spots, or cable slippage.

Cradle Compounding Kits

Need more lift capacity? A 316 Stainless Compounding Kit multiplies lifting power by distributing load over multiple sheaves, bolts, and lock washers.

Axle Bolt Kits with Zerk Fittings

Smoother operation starts with the right hardware. Our axle‑bolt kit includes a hex nut and lock washer—plus an integrated grease fitting to cut maintenance time.

Drive‑Pipe Cable‑Attachment Bolts

Keep cables anchored securely with 316 stainless drive‑pipe bolts. They’re engineered for salt spray, vibration, and decades of service.

Choosing the Right Material

18‑8 Stainless Steel

The economical choice for mild marine exposure—excellent rust resistance on a budget.

316 Stainless Steel

The premier option for saltwater. Added molybdenum ensures top‑tier pitting resistance and decades of service.

Galvanized Hardware

Zinc‑coated and cost‑effective for freshwater or light‑duty installs.

Standard Hardware & Bulk Options

Upgrading your lift often means swapping ancillary hardware—hex‑cap bolts, flange bolts, fender washers, carriage bolts, nuts, lock washers, and more. We stock these in both 18‑8 and 316, with savings on bulk packs for large projects. Mix‑and‑match standard pieces with our specialty lift components for a complete solution.

Protect Your Lift — and Your Time on the Water

From 4" aluminum sheaves to 316 axle‑bolt kits and compounding kits, quality parts mean fewer surprises and more boating days. Combine routine inspections with marine‑grade materials to keep your lift dependable year‑round.
