Ridge Grappler size

ecowan · Nov 6, 2024

I am looking to get new wheels and tires for my 21 trx. I am planning on buying Weld Ledge 6 wheels 20x10 with -18 offset. I also know that I want Ridge Grapplers I just can’t decide on a size. I have attached pictures to a truck which is exactly the look I am going for. The truck pictured has 37x13.5 with 20x10 wheels and I am assuming -18 offset. The side photo looks like the front is noticeably lower than the back which makes me think it has no leveling kit, if anyone has any idea I would appreciate it.

Looks like 37x13.5R20 on the sidewall. Doesn’t look like it’s lifted or leveled because that front tire is stuffed in there pretty tight. Probably rubs pretty hard. Just guessing tho

I'd do 35s with the 20s

As far as the offset you could just call them and have that answer in a few minutes. Rather than a spacer kit for front level, hit up @Nick797

We can get you setup with Weld Ledges and the appropriate tire for you! Give us a call or shoot me a message. Weld is 20% off right now & I can combo in some tires & lugs as well for you.

IIRC that truck did not have a level as the shots are pretty old when there wasn't many options out there aside from Foutz.

325/60R20 basically a 35 1/2” tire. Shown here on 20x10 -19 offset wheels on stock suspension. Slight rub every once in awhile.

I ended up going with Ebiach level kit and 37x13.5 Ridge Graps with 20x10 -18 wheels

I’m pretty sure these are 20x12 with a -44 offset.

Pictures? How are those tires with launching? Grip on wet pavement? I had trouble with them being useless of wet pavement in a gmc Sierra so hesitant to put them on a trx. But getting ready to get the eibach 2.7” front springs and 37s of some kind or stay with stock springs and 35” bfg ko3s. I have airbags in rear so it sits even higher than stock with them even at low pressure.

I just got them installed today everything has been good so far. It rides very close to stock. I haven’t launched it or driven in rain but I had them on a Jeep Wrangler and they were great. I’ll update when I experiment

Comparing a Sierra to a TRX is like comparing a fwd civic to a Subaru in the rain at a light.

Speaking of Eibach springs, anyone know how much lift their HD rear springs are?

It all depends on how much weight. Wouldn’t recommend running the HD springs without having some weight.

According to the site 2.6 to 1.6 rear lift

Designed for use with OE shocks Listed rear lift heights range from 0lbs(1st height listed) to 500lbs(2nd height listed). Only recommended to run at fully load height, other heights listed for reference only. Too much lift will cause poor ride quality.

Check this doc out for more reference. Tells you the height based upon the weight.

Well the Sierra (6.2) had half the drive wheels and half the torque, so roughly the same forces at play at the rear wheels. Obviously the same power at the front as well in the awd trx helps it get going, but that’s not really the topic at hand. Why have a tire that may slip at an unfortunate time or that you have to baby the throttle? Should we hope the awd makes up for poor tire performance? Not a $2000 experiment I’m interested in making but if people on here like the cold/wet performance then I may be willing to try again if the bfg ko3 isn’t going to come out in a 37 soon.

I ran two sets of Ridge Grapplers on my Tundra and Laramie here in the Pacific Northwet and never had any of the issues you're describing in the rain. We also get 70" of snow and they performed above average.

So 2.6 with no weight is what it looks like. Thank you

Is that just the 1.6” coils in front? Or did you do all 4 springs?

pilot650 · Nov 13, 2024

Ridge grapplers look great but I just looked to tire rack for some more objective data and it is similar to what I have experienced in years past so I am hesitant but not finding many options in 37x13.50x18 that have an aggressive look that aren’t Mud terrain.
