I’m confused here- it’s a torque multiplier and more compact than your 4-5’ breaker bar but you later say that it works with your existing torque wrench and breaker bar. So I guess it enhances torque but not enough to replace the breaker bar? I’ve never removed CL wheels so I’m not exactly sure what works best. Thanks for helping me to understand.
Yes, it just multiples the torque by a factor of 3, which means that standard 18”-24” breaker bars and torque wrenches used for 5-lugs can be used. Much more convenient than trying to schlepp 48”-60” long bars…
I highly recommend getting the Neiko 03715B torque multiplier wrench. It is far more compact than the massive 4~5' long breaker bar and torque wrench. I purchased mine last year and it works like a charm. Since I track my car, I take my wheels on and off quite regularly for tire rotations or brake pads replacement. It is compact enough to fit in my track side toolbox that I carry with me and works with my existing breaker bar and torque wrench.
I just checked this out and found a review that's thrown me... What's your experience please?
Amazon Review:
"The review is not a reflection of the quality of the product. It's seems to be well build. The carrying case is good as well. The problem is the product label and description do not match the wrench. I send the first one back and the second one is built the same way. The desc. reads 3.3:1 ratio. The label on the wrench reads 3:1 ratio (can be seen in the pictures).
The actual ratio is 3.5:1. The only reason to use a torque multiplier is to torque thing right. If the product is not manufactured properly and the user does not catch it the torque will be incorrect. For example: If your nominal goal is an output of 500 FT.LBS. use the ratio of 3:1 printed on the label your input torque should be 166 Ft. Lbs. (not counting inefficiencies) However, if you input 166 ft. lbs. into the head which is actually 3.5:1 you will be applying 581 ft. lbs. of torque which could be too much.
There is no seller to contact to clear this up. Amazon is great and sent the replacement right away but unfortunately it was built the same as the first one."
The RENNtorq Center Lock Tool V2 is an innovative system for Porsche centerlock nut removal and installation. The system uses a precision torque multiplier, in conjunction with a custom reaction arm specifically sized for 992/991/997/718 applications, to greatly reduce the amount of input torque required to loosen and tighten the factory centerlock nut. The tool has been tested on the 992 GT3, and 992 GT3RS with magnesium wheels. For 992 GT3RS with aluminum wheels please contact us for a specific solution.
A motorsport grade torque multiplier is used to convert 95 lb-ft of manual input torque to 443 lb-ft of output torque. The multiplier has a 1/2" drive input, and a 3/4" drive output which allows for a direct connection to the factory supplied socket. Each multiplier is tested and certified to a specific multiplication factor (range of 4.70:1 - 4.75:1) which allows you to precisely calculate the input torque required to secure the center lock nut. The custom reaction arm counteracts the torque applied to the nut by applying a counter force to the spoke of the wheel. The reaction arm is covered with a polymer material strong enough to apply the required force, but soft enough to eliminate any risk of wheel damage.
