Superwinch SP 45SR 4500 lb ATV/UTV Winch with Synthetic Rope
Shipping calculated at checkout
In stock
The Superwinch SP 45SR is a 4500 lb winch, synthetic rope equipped, for ATV and UTV owners who want serious pulling power without the weight and sharp burrs of steel cable. It runs a 1.8 HP permanent magnet motor through 198:1 three-stage planetary gearing and spools 1/4 in. x 40 ft. of synthetic rope through an aluminum hawse fairlead.
A synthetic rope winch is easier to handle with gloves, will not leave broken wire burrs, and keeps weight off the front of the machine. Superwinch backs that rope with a welded steel drum, a full load holding automatic brake and a fully sealed drum, gearbox and contactor rated IP68 for water and dust.
Shoppers weighing a synthetic winch against steel will find this Superwinch 4500 model shares its 12V winch platform with the SP 45, just with synthetic line. That makes it a capable 4500 lb UTV winch for side-by-sides, a synthetic rope ATV winch for heavier utility quads, and a sensible pick among ATV winches when you want a UTV winch synthetic rope setup that is easy to handle.

Built To Solve: Heavy, Hard-To-Handle Winch Line On Your ATV Or UTV
- Getting stuck alone in mud, sand or snow with no second machine to pull you out
- Steel cable that kinks, frays and leaves sharp burrs in your hands
- Extra weight hanging off the front of a light ATV or compact UTV
- Winches that quit after a few water crossings because the gearbox or contactor is not sealed
- Slow, awkward clutch engagement when you need to free-spool line fast
Best For: Mid-Size And Full-Size UTV Owners Who Want A 4,500 lb Recovery Winch
- Side-by-side owners who want more pulling headroom than a 3,500 lb winch offers
- Trail, mud and snow riders who often recover their own machine or a buddy's
- Work and utility riders who drag loads or clear trails
- Riders who prefer lighter, easier-to-handle synthetic rope
- Lighter ATVs may not need the extra capacity; the SP 35SR is the 3,500 lb version
- Prefer steel wire rope? The SP 45 is the same winch with steel wire rope and a roller fairlead

Fitment
Superwinch builds the SP 45SR as part of its SP Powersports Series of ATV/UTV winches. It is not a vehicle-specific kit: it bolts to a winch mount, winch plate or winch-ready bumper that accepts the 4.88 in. x 3.0 in. (124mm x 76mm) mounting bolt pattern and runs on a 12V DC electrical system. Superwinch does not publish a make, model or year fitment list for this winch, and a vehicle-specific mounting plate is not listed among its included features. Confirm that your machine has a compatible winch mount or bumper, room for the drum and fairlead, and a suitable battery connection before ordering. Fitment is not guaranteed on applications we have not listed.
FAQ
Why choose a synthetic rope winch like the SP 45SR over steel cable?
Synthetic rope is lighter than steel cable and easier to handle without sharp wire burrs. The SP 45SR runs 1/4 in. x 40 ft. synthetic rope through an aluminum hawse fairlead. If you winch across sharp rock often, the SP 45 with steel wire rope may suit you better.
Will the SP 45SR hold a load on a hill?
Yes. Superwinch fits the SP 45SR with a full load holding automatic brake, and the 1.8 HP permanent magnet motor provides dynamic braking, so the load stays put when you stop winching.
Does the SP 45SR fit my ATV or UTV?
The SP 45SR is a universal ATV/UTV winch with a 4.88 in. x 3.0 in. mounting bolt pattern. Superwinch does not publish a vehicle-specific fitment list, so you need a winch mount, plate or winch-ready bumper for your machine that accepts that bolt pattern.
What comes with the Superwinch SP 45SR?
Superwinch lists the winch with 1/4 in. x 40 ft. synthetic rope, the aluminum hawse fairlead, a heavy-duty 1/4 in. clevis hook, dash-mounted control switches and a 10 ft. handheld remote with a handlebar rocker switch. A vehicle-specific winch mount is not listed, so plan on one for your machine.
How hard is the SP 45SR to install?
Most owners with basic tools can mount it to an existing winch plate or bumper, route the wiring and connect to the 12V battery. Superwinch publishes installation instructions for the SP Powersports Series, available on this page. If your machine has no winch mount yet, add one first.
Should I get the 4,500 lb SP 45SR or the 3,500 lb SP 35SR?
A common rule of thumb is a winch rated at about 1.5 times your machine's loaded weight. The SP 45SR gives mid-size and full-size side-by-sides more headroom, while the SP 35SR is a lighter option for ATVs and compact UTVs.
Why Superwinch
Superwinch is a long-standing name in off-road recovery winches. Every Superwinch winch in the SP Powersports Series uses a steel drum rather than aluminum, a no-bind twistlock clutch and a fully sealed drum, gearbox and contactor, and Superwinch backs the series with a limited lifetime mechanical warranty and a limited 3-year electrical warranty.
Complete Your ATV/UTV Winch Setup With The SP 45SR
Before you order the Superwinch SP 45SR, confirm your machine has a winch mount or winch-ready bumper that accepts the 4.88 in. x 3.0 in. bolt pattern and decide whether 4,500 lb and synthetic rope are the right match for your riding. Then round out the kit with a tree protector strap and a snatch block so this 4500 lb synthetic rope winch can handle angled and double-line pulls safely.
