Best rear kit in my opinion..simple, efective and cost is lower than the other brand, good for averaged low buck mecanic like me! ;o)

need to do one for the 67-69 camaro torque arm

[@3rdGenC10s]

Looks like a well designed kit. I like the full capture of the axle tube. How much drop are you able to get total?

[@tcimuscle]

It is the maximum allowed and still keep the stock bed floor. At full compression the top of the axle is roughly 1/4" away from the bed floor. What that equates to as far as drop is tough to say given the truck we began with was already lowered. At the lowest setting the fender to ground clearance is 24.5” with 29” tall tires.

im sure its fine the frame is very strong in that direction but a cross member wouldnt hurt

[@beaupatterson1527]

Weekend project material? Also do you think it’d fit a dodge 9.25 rear end with minor modifications

[@tcimuscle]

The only issue would be the axle tube outside diameter. It would need to be 3" or our axle bracket will not fit. In those cases we have a weld on bracket but it is also designed for a 3" axle tube but would be infinitely easier to modify to work.

Yes, it can. Drop our tech line an e-mail for details. [e-mail]

[@OTTO_Man]

Can this system be adapted to a c20 (3/4 ton 2wd) suburban or do you offer another option?

[@tcimuscle]

We haven't been able to confirm if the 1/2 & 3/4 ton factory leaf springs are the same length. If they are then the front leaf bracket is in the proper location. If not we would have to provide a measurement for placement.

[@shotgunpsycho]

1/2 ton leads are about 4 inches shorter than 3/4.

[@sergioc2342]

With that rear set up whats the widest wheel you can fit ?

[@tcimuscle]

We haven't tried anything wider than 12.5". Mainly because the good performance tires are limited to 335/345. There is still more space for width beyond that but not much.

[@79seirra]

Track bar looks very close to driveshaft. Any risk in applications where the drop is not so low?

[@tcimuscle]

Not at all, the track bar clearance remains the same regardless of which adjuster hole the shock is placed. So long as the pinion is adjusted properly there is plenty of clearance.

[@vagabond3045]

[@jimmysapien9961]

[@pjt-kl7mb]

Why you removed the shock bracket and when you installing de coil over the bracket is there did you put the bracket back?

[@tcimuscle]

I'm not sure I follow but this video was done using two different trucks. The original truck was already modified with another companies product. We finished the manual with another truck. So you are seeing video clips form both trucks.

[@blackseabrew]

I have a 1987 Chevy V10...4WD. With dual fuel tanks. Will the 4 Link work for this application? Not interested in lowering. Was looking at a 2" lift actually.

[@tcimuscle]

While the kit will bolt in to the chassis the kit is designed for a significant ride height drop. With a longer shock it could be raised, some, but not even close to back to stock height. Let alone raised from stock.

[@user-bj1uq6je3s]

Can I put it on a long bed c 10 1975 scottsdale.And is that kit adjustable? My truck is currently 6 inch lower in the back,and I want to keep the same high

[@tcimuscle]

Yes, this kit will also work on a long bed. Our ride height is adjustable so you can set it at 6" +/-1"

[@philipschuetz4856]

Do you have a kit for a 86 1 Ton non fully. Really like the video

I'm not 100% certain if the frame rails (in the area of question) are the same on the 1 ton or not. Drop the sales department a line, they'll know. [e-mail]

[@rcmike09]

Is there a reason not to weld the c notch in along with the bolts?

[@tcimuscle]

The only issue with welding it will be warping the factory frame. It can be done just do it one inch sections and let them cool off completely.

[@vagabond3045]

What would be a good pinion angle for this kit

[@tcimuscle]

You want the pinion angle to be up the same degree angle the engine/tranny is down.

[@charlieduran7791]

Can't believe you guys don't make a kit for 88-99 OBS!

[@tcimuscle]

We do a ton of testing and R&D on product before releasing them. The C10 product line has been nearly 8 years in the making. Which, unfortunately means other product lines are behind schedule. We will be offering some sort of rear suspension for the GMT400 at some point.

[@jeremythompson3687]

Do you have something like this for my 84 Chevy G30?

[@tcimuscle]

Sorry, we do not have anything specific. We do however have some universal 4-Links that may work. Give our tech department a call and they can walk you through taking some measurements.

[@ivanhernandez983]

Would this work if I want to put my truck on bags?

[@tcimuscle]

Yes, Ridetech shockwaves are direct replacements to these coilovers.

[@bonethang374]

When adjusting the upper link bars for pinion angle, if you have to turn them out more than 2 full turns will it put any dangerous amount of bind on the coilovers? I just installed this kit, it’s awesome. But setting the bars up as shown here only nets me about 1.25 degrees up. I need to take the upper bars out a few more turns to get it to 3 to match the output shaft of the tranny. Being as the coilovers are mounted to the c-notch between two stationary brackets. I’m worried about the bottom attachment bolt pulling the coilovers into a bind when the axle rotates when I adjust the pinion angle. Or is 2 extra degrees of upward rotation minimal and I’m just overthinking? Thanks in advance !!

[@tcimuscle]

As long as you can get the lower shock bolt in and out you're fine. There should be enough deflection in the bushing to allow it. If not we can change from the bushing to a bearing. Also, if adjustments are needed beyond the specs laid out in the manual we'd suggest adjusting the lower bar first. The lower bar will not change wheelbase as much as the upper bar will.

[@bonethang374]

@@tcimuscle Thanks for the response. That’s interesting. I currently have the upper bars turned out two more times than what’s shown in this video. Would leaving the upper bars like I have them but turning the bottom bars IN the same amount the upper bars are turned OUT rotate the axle upwards but leave my wheelbase the same as it was or should I turn the upper bars back in to what is recommended and use only the lower bars for pinion adjustment? I’m not sure there’s enough thread on the lower bars to turn them in as far as needed, though.

[@tcimuscle]

@@bonethang374 Don't over think it, we're talking minimal differences in wheelbase. Since you've already turned the uppers, I'd just leave them and fine tune the pinion with the lowers now.

[@bonethang374]

Will this work on squarebody burban also?

[@tcimuscle]

We have not been able to confirm it at this time. It "should" be the same as the Blazer which we have confirmed fitment on.

[@rcmike09]

Would this kit work on a c30 dually?

[@tcimuscle]

We can't confirm or deny if it will fit. The frame profile appears to be similar/same as the C10 in the drawings we have found. The C30 definitely uses the same front leaf hanger. Which is the most important part of the kit. If you're local to us and can bring the truck without a bed we can confirm.

Whats the rated horsepower? Could your kit handle say 1000 to the wheels?

[@tcimuscle]

We'd be more worried about the frame at those power levels. But honestly without traction horsepower doesn't mean much. So if you plan on installing slicks and running the drag strip we offer weld on axle brackets that would be the preferred option in your case. We would also suggest upgrading from bushed link bars to Ridetech R-Joints.

@@tcimuscle hmm is there an email or message app I can contact you guys at? Don't want to put to much of my plans out there in the air but I will say this, the last thing I ever would do is run fat slicks on my c10 only because that's exactly what everybody does. I'm definitely not going that route. You say you have weld on brackets, is that a complete kit coilovers and all?

[@steves759]

Not bad looking but I will be more interested when they start making these kits to take advantage of the maximum tire width. In other words quit bolting them to the outside of the frame. Make kits moving everything inboard so we can put some meat close to the frame please.

[@tcimuscle]

This kit allows for 335 tires with room to spare. The main reason you don't want to move the brackets inside of the frame is the loss of roll resistance. We offer universal Pro Street 4-Links specifically for those situations.

@@steves759 This bolt on kit wouldn't provide enough anti-squat for a drag set up anyway. The universal kit is so much easier to work with for what you want.
