Re: No Limit Trailing Arm Rear Suspension
Looks great! We are now stress testing a few versions of a notch brace. I know that no one else has done this, as we are testing a few others as well. Load stress of mod rails vs. OE rail. Twist, vert. and horiz. loads. Probably 30 days to production unit.

So there is about a $350 difference between this setup and the fatbar when they are both using Ridetech shocks. What are the advantages of going with this vs your fatbar setup?

The Fatbar was originally designed for 55-59 Chevs and 53-56 F100s. (sorry for the F word) And, over the years, we tuned on the design to get the best ride and handling we could from a classic truck. It's advantage when compared to the O.E. trailing arm was in Instant Center location/tuning, and the lack of binding during articulation. (we didn't have Monster balls back then) But remember, the Fatbar has parts that MUST be welded to the axle housing. Thus, the install takes a little longer, and requires more tools and skill. In head to head competition, the Fatbar may win out due to it's ability to launch and exit the corner. On the road, the trailing arm may be a little more compliant due to it's longer travel. As for cost, an increase in hardware offsets some addition labor to install. Take your pick, it's a Win-Win. |
Re: No Limit Trailing Arm Rear Suspension
Has anyone figured out which diff covers fit with the panhard bar?

Re: No Limit Trailing Arm Rear Suspension
Hey Rob,
Any pictures of the c-notch? |
Re: No Limit Trailing Arm Rear Suspension
Hey Rob,
Any updates on the c-notch? Thanks |
Re: No Limit Trailing Arm Rear Suspension
Getting close. matching the bends to fit the OE rail is harder than it looks. We should have formed parts next week. Fixtures and press jigs are ready. - It won't be long.

Re: No Limit Trailing Arm Rear Suspension
Cool stuff here. Any updates/opinions from those who have purchased?

Re: No Limit Trailing Arm Rear Suspension
Hey Chris. I purchased and installed the kit with the Ridetech three way adjustable shocks from Rob a couple of months ago. I have a 72 Chevy long bed that is pretty much stock except for the suspension and wheels/tires. I removed the bed for the installation and everything went pretty smooth. Drilling out the stock rivets is the worst part of the job. Everything is great quality, and with a little careful measurement, my truck didn’t require any adjustments in the rear for a perfect four wheel alignment. I haven’t had a chance to put it through the paces on a track, but the ride and handling is amazing. I had to add more clearance to the inside wheel houses to accommodate the 345/19X12 wheels and extra axle articulation for street driving, but the axle tracks the pavement really well and the rear axle hop/oversteer of death is greatly reduced. Rob did a great job!!

Re: No Limit Trailing Arm Rear Suspension
Any provisions for e-brake cables on the arms?
|
Re: No Limit Trailing Arm Rear Suspension
We did not put any cable mounts on the arms fot the OE style cable. Currie and others have bolt-on tabs that can be used. When running Wilwood, or other aftermarket disc set ups, custom cables can be made for you at www.controlcables.com We run the cables through the arm, notice that they are ported on the top/front and side/rear for cable housings.

Re: No Limit Trailing Arm Rear Suspension
What anti-sway bar works with this kit? Is it just the hotchkis blade style? Looks like your top mount *might* work. Looking forward to notch updates

Your options for trailing arms on a 73-87 are CPP or Porterbuilt, maybe hotrods to hell if they are still around. |

2 more days and the c-notch will be here.... Monkey junk ;)

Re: No Limit Trailing Arm Rear Suspension
Rob, I know you guys install 9 in floaters on your frames and would like to have one on my truck. Is there any chance you could sell the rear end prepped for this trailing arm setup? I'm all about that bolt-in ...
|
Re: No Limit Trailing Arm Rear Suspension
We sure do. We can prep both standard 9" big bearing housing/axles. or floaters. Pricing breaks down like this.
9" heavy duty Moser housing with billit Torino (big bearing late model) ends, pinion centered, with fill and drain added + Moser 31 spline axles with access hole, 2 1/2" offset, bearings and seals and 1/2" x 20 studs. Standard C10 width is 63" WMS (wheel mount surface) - can be 62" or 61", no extra charge. With No Limit brackets welded* $1,295.00 9" BBLM brakes 11" Explorer style, drilled/slotted = $590 12.19" x 4 piston Wilwood = $895 13" x 4 piston Wilwood = $1785 9" Moser heavy duty floater housing, fill and drain added. Steel hubs and drive plates, all bearings, seals, retainers, 31 spline axles. Pinion centered, 63" std WMS. - 60" to 62" avail also. No Limit brackets welded = $1395 Floater brakes 11" Speedway style with Wilwood Superlite (no E Brake) $745 12" Wilwood w/E-brake in caliper $895 13" Wilwood with Superlite and Mech spot E-brake caliper $1680 For drilled/slotted rotors on these kits add $90 * Brackets not included, but are part of No Limit suspension packages. |

So no welding required just bolt it in? What do you guys carry as far as the 3rd members and what would you recommend for autox? |
Re: No Limit Trailing Arm Rear Suspension
Yes, no welding to the housing needed. For our FatBar, there would still be some welding needed for the Panhard mount, - but, we are going to change C10 FatBar kits to use the new C10 Panhard from the Trailing Arm kit, so those will be bolt on as well after Oct-1. (maybe sooner.)
As far as gears, a lot depends on the trans and tire diameter. For highway, we like to see about 2400 rpm at 70 to 75 mph. So the O.D. ratio comes into play. For most autocross, GoodGuys and USCA are mostly 'first gear' coarses, so as a rule, in first gear you want about 9.5" of tire roll per 1 RPM. So tir diameter can play big into the gear ratio here. 3.5 or 3.73 is usually pretty close. |

Re: No Limit Trailing Arm Rear Suspension
Is that a shallow notch compared to CPP or is the center section just longer?

Re: No Limit Trailing Arm Rear Suspension
Is Hotchkis the only rear anti roll bar that works with the No Limit trailing arm setup? I thought I read before that the No Limit rear anti roll bar setup won't work?

Re: No Limit Trailing Arm Rear Suspension
OK, YES, the No Limit notch is 'shallower' or - not as deep - as some others. This is on purpose. With this depth, and a 1/2" bump stop, when the axle tube hits the bump, the top of the diff housing will be 1/4" from the bed floor. So, any more notch would A) needlessly weaken the frame rail, and/or B) require a bubble or tunnel in the bed floor to clear the diff housing. Since this notch was developed with "stock rails" in mind, we decided to match that idea with a "stock bed floor" concept.
As for the rear bar on our Trailing Arm kit, we are still set up to use the Hotchkis bar, if desired. Now, Autocross testing has yielded faster laps with-out the bar. The normal street driving, even on the Dragon, is more comfortable with-out the bar. But, high speed open-track laps are faster with the bar. **Factor in here 200 TW tires and some Aero to get them to stick, otherwise, no bar is a better choice. |
Re: No Limit Trailing Arm Rear Suspension
I like the shallow notch in that it gives people another unique option.
Re: sway bar, that's not what I expected! Any idea why autox is faster with no rear bar? |
Re: No Limit Trailing Arm Rear Suspension
Auto-X (OK, Fast Auto-X) is probably the hardest challenge for your suspension/tires than anything else (ON-road competition) we see higher shock and spring rate changes than anything else. Honestly, many Auto-X'ers have surpassed the G force loads of a lot of road racers, it's just that on an Auto-X coarse, the 'time' of the G event is much shorter. The 'violence' of the tire loading is much harsher. So, allowing the body to roll a bit more (still with the rate controlled by the shock) slows down the rate of tire loading and allows the tire to get a grip for a bit longer.
