73-87 2wd lift with 33x10.5x 18 Nittos

[Justins76]

To discuss this topic go here-"2wd lift and new 18's w/ 33x10.5 Nittos"


18x8" Chevy 6 lugs wheels off a new Z71, Nitto Terragrappler 33x10.5. Rear 2.5" Rancho lift blocks with Bilstein 5100 extended shocks. The front has 88-98 Rough Country lift spindles. I'm using the Moog 6454 HD springs. I will have to see if I can get it aligned with them, but the tops of the tires are angled out some. May have to put in shorter springs to get the correct camber. Here's how it looks so far.

One problem I ran into was the 88-98 outer tie rods connect to the spindle from underneath and caused interference with the sway bar. I do not know if this would be a problem with the stock sway bar. Since the tie rod joint is smaller then a 73-87, what I did was get a taper reamer from summit and reamed it from above and used the stock tie rod.

The brake hoses are from a 88-98 and they connect to the frame differently. If you clock them just right, they will fit into the hole in the frame and use a horseshoe shaped clip to hold it in.

The spindle, rotors, bearings, calipers, pads, ball joints and hoses I used were from a 1994. The rest is stock 73-87 parts, with 1 ton lower control arms.

You have to use 88-98 rotors and calipers. Since the 88-98 ball joint is bigger, it wont fit 1/2 ton arms. I'm using 88-98 Raybestos PG (formerly Spicer) ball joints.

For the rear I used blocks and longer shocks with 4wd axles since I'm using 6 lug wheels.

I am currently working on a spreadsheet with all the part numbers. I will also be posting pics with height dimensions.

Got it aligned. They used almost no shims but got it in spec. I had to change how the brake hose attached to the control arm because it was pulling tight on turns. Also had to trim the fender at the front because of the tread rubbing going over bumps with the wheels turned. With my digital level, I get about .1-.2° angle down in the front. Ride is smooth on the freeway and curbs are easier to hop



Some dimensions with a tape measure.
