What You Need To Know Before Buying A Winch
So you’ve read our story on why you need a winch and are convinced that this is the next big purchase for your 4×4. Picking the right one can be a daunting process though. You can start by first determining what size winch you need. A good rule of thumb is to select a winch with a rating one and a half times higher than the weight of your vehicle. Why? There are a couple of reasons. First off, when stuck there is often drag on your rig, whether it is suction from mud or the resistance from a huge boulder you are trying to pull a differential over. Also, winches are rated for their maximum pulling power on the first wrap of cable on the drum. Each additional layer increases the diameter of the drum, so the pulling power decreases by approximately 10% per layer. It is just like larger tires change the effective gear ratio of your vehicle.
Determine Your Budget
Once you know what size winch you need, evaluate which models fit in your budget. Winch prices vary wildly from a few hundred dollars to well over one thousand dollars. Manufacturers, like OPENROAD 4WD and Warn, have more than one offering in popular sizes to meet your needs and your funds. The difference in price is a function of features, construction, and where the winch is made. Elements including synthetic cable, aluminum fairleads, and winch thimbles are worthwhile upgrades. If you are on a tight budget though, we would hold off on purchasing these items since they can be added in the future as funds allow.
The large clutch lever on OPENROAD 4WD winches is easy to operate, even if it is muddy or you have gloves on. You are wearing gloves when using your winch, right? The downside to the larger clutch lever is that you might need to rotate the housing on the winch body for fitment with some bumpers, but this is easily accomplished with an Allen wrench.
Construction and Electronics
Construction is not as easy to alter after the purchase as the winch cable is. More expensive winches tend to be stronger, more reliable, and more efficient as a result of better electronics, improved sealing from the elements, and higher strength materials. OPENROAD’s OC and NP01 series winches actually use the same 6.6 horsepower motor, three-stage planetary gears, and lifetime mechanical warranty. How do they differ then? The inductive braking on the NP01 creates 66% less heat, making it well suited to synthetic winch line. This braking system also allows for more precise winching rather than the spool slowly coming to a stop after you release the controls. Other differences between the OC and NP01 include a wireless remote control and increased waterproofing.
Even the best winch on the planet can fail when you need it most if it is not installed correctly. Take care when routing the wiring for your winch. Cables should be routed away from the exhaust and sleeved anywhere they pass next to sharp edges. If you are intimidated by the installation process. The OPENROAD's channel has tech videos for your need.
If your adventures often involve water and mud, buying a waterproof winch should be a priority. The IP rating (Ingress Protection) classifies and rates the degree of protection provided against the intrusion of not only water, but mud, dust, and other debris that are commonly encountered on the trail. The first number in an IP rating refers to solid particle size. Six is the highest rating and is dust tight. The second number is the resistance to liquid. Seven denotes the ability to submerge the winch up to one meter for up to 30 minutes. Eight designates the ability to continuously operate the winch in water up to three meters deep.
While more expensive and susceptible to abrasion, synthetic winch line is lighter and safer to handle than steel cable. We recommend roller fairleads with steel cable and aluminum hawse fairleads with synthetic cable. Aluminum hawse fairleads are lighter than roller fairleads and provide a better approach angle. They also are a requirement for synthetic lines as their smoother surfaces won’t fray or damage the line.
Pulling power is largely a function of gearing, just like the crawl ratio of your vehicle. Smittybilt’s 9,500 and 13,000 OC winches actually use the same powerful 6.6 horsepower series wound motor. However, the weight ratings differ significantly. This is common between winches of the same brand and model line. The difference in pulling power is that the 9,500 uses a 161:1 gear ratio, while the 13,000 uses a 265:1 gear ratio that provides more pulling power at the expense of line speed. If your winch is stalling on a short pull, adding a snatch block and attaching the cable back to your vehicle will increase the pulling power through the mechanical advantage, similar to lowering the gear ratio. This also has the added benefit of spooling more cable off the drum.
Wireless winch controllers offer the ability to operate the winch from a safe distance, and you don’t have to trudge through the muck to hook them up. They do require batteries to work though and can be finicky if they do not have a strong signal. The controllers included with OPENROAD’s NP winches are the best of both worlds as they can be operated wirelessly or plugged in.
Other factors that impact performance (and your budget) involve the charging system of your vehicle. Winches draw a large amount of amperage, more than the typical alternator can provide. Fortunately, we only use our winches for short periods so the battery can power the winch and then the alternator recharges the battery. Starting batteries do not like to be fully discharged repeatedly though, so consider replacing the starting battery with a deep cycle battery or adding a second battery. High-end winches are often more efficient, so you may spend more on a winch but not need to add a deep cycle battery immediately.
While there are a lot of factors to choosing the right winch, if you are armed with the correct information, the purchase process doesn’t have to be painful. And neither does your next recovery effort!
Winches draw a large amount of amperage. Loads of 300 amps are more than the typical alternator can provide. Your vehicle’s battery makes up for the difference in amperage, and the alternator recharges the battery. Deep cycle batteries, or even dual batteries, are useful upgrades if you do a lot of winching. You always want the vehicle winching to be running if possible.
If your adventures often involve water and mud, look for a winch with a minimum of an IP67 rating. An IP68 rating is even better as this denotes that the winch can be operated continuously underwater without harming it. Those who spend time in the mud often prefer steel cable to synthetic as it is not as susceptible to abrasion from the dirt.
