Sun Company 201-F Lev-o-gage Inclinometer | USA-Made Level Gauge for Off-Road Vehicle, Jeep, Truck, RV, Camper, Trailer, or Boat

Easy to install

Latest Update, Oct 5 '25; Customer service was much more helpful than expected. I'd had trouble with my inclinometer sticking in random spots, due to a possible glitch in the particular batch, in production, there is also a possibility too though that my desert (hot) environment could be a contributor to the demise of the unit. EDIT/UPDATE Oct 1 '25 Sun Company made this item right for me, so I have added back three stars. For some reason the bearing/indicator as written about below, wound up sticking randomly, so it would not give readings as it tilted to different or new angles. ---------------- Original review; This inclinometer worked well for the first few weeks, but annoyed me that quality control allowed this to pass with a discoloration spot about 3/16'' , 3 or 3 mm at about 20 degrees on one side. The unit has not been damaged in any way , but now sticks and needs to be tapped hard with a hard object to move, only to stick again a few minutes later, so it will read zero if that is the last place it stayed for a minute, no matter what the actual angle. For my application, this is extremely inconvenient and literally almost downright dangerous.

I installed on my tractor it works perfectly to prevent turnovers. So I purchased another one to put on my zero turn mower.

These devices are similar to the old aviation turn and bank indicators which consisted of a ball in a liquid filled track. Combined with a turn indicator and a compass early fliers could confidently fly through clouds. Another historic use was on sailboats, to help trim and balance the sails by adjusting heel angle. These are sold to put on ATVs and tractors but should be used mostly as a cautionary tool and not as any hard and fast safety device. While a well sailboat can be designed to become more stable as it heels the opposite is true of a tractor. Their major safety features include counterweights, wheel weights, wide track wheels (especially not those tricycle wheels popular 80 years ago) lowering or entirely removing the front lift, carrying loads both front and back as low as possible, always prepared to dump them on the ground if they are a factor towards overbalancin, carrying the backhoe turned to the uphill side, plus seat on belts all the time and a solidly sturdy well designed ROPS which is never lowered at work, no passengers, cell phones or other distractions, Finally, rollover safety is one reason tractors have a gear shifter and 4WD. What is a safer ride through the woods in FWD first gear low range is not so safe in 2WD third gear high range. Can't use 4WD in paved areas, but these are usually flatter than unpaved areas. These instruments need a vertical surface for mounting since any forward or backward tilt changes the geometry of the ball in alcohol leveling. Unfortunately the only forward looking vertical surface I have available on the tractor is the mounting brackets for fork lift/loader but these are about an inch too narrow between metal weldments. So next best thing was to mount two of them on left and right ROPS brackets where I can see them when I can't watch the front wheels, due to backing or carrying a load. Oh, did I mention that one of my uncles died in a tractor turnover accident while clearing brush from a terraced cattle field. It was on one of those tricycle wheeled old Fords with no seat belt, no ROPS, no extra weights, maybe too much speed (about the 50th time he'd cut that same field over a lifetime) and weeds obscuring the exact pathway.

It is great for what it is... A simple inclinometer. The adhesive is good and it is easy to install. The size is good and the numbers are easy to read. The price is good for what it is and so far it has not leaked. I am very happy to have this on my tractor.

I actually used it yesterday, the ball flows freely from the left into the right and appears to be sturdy. Of course just like other reviews say, the tape on the back is junk, knowing that I replaced it with some good 3M adhesive. Otherwise, a good buy.

Really great quality. Easy to read

Garbage. I though nothing could go wrong with a gravity actuated level but I was wrong. It does not work. The ball is stuck on zero. Don't waste your money. After I wrote a very negative review I just forgot about this and moved on. Last week I received an e-mail from the company offering a refund. I refused because I no longer have the gage to return. The company sent me a refund anyhow. I believe that shows integrity and also they are trying to do right by the customer. Although I am not happy with the item I purchased I would revisit this vendor for future purchases. Thank you

We needed to know the degrees a bed was tilted for an LTC facility for a loved one. This does the job well.

Me gusta rm general, me sirve para observar y contrapesar en mi lancha la estabilidad de la misma

Utilizzato per offroad risulta essere comodo, e molto valido grazie alle dimensioni ridotte e alla sua forma.

Good product
