New Shocks / Droop and ride height measurements

Post by Laredo Matt »

I'm getting ready to purchase shocks.

Primary use is on road. 90%+. I don't plan on doing any hard offroad, light duty only and probably towing a boat / motorcycle on some fire roads to get to campsites / boat launches.

I've looked at the Bilstein 5100/5125 series but am leaning to the Fox 985-24-051. I just like the remote reservoir look and can get them tuned and rebuilt in the future if desired.

Fox recommended a shop in California that are tuning specialists and I've been talking to them. They asked for a series of measurements; full droop, ride height, uplift as well as shock orientation from 90 degree (front to back, side to side) when mounted.

I'm looking for some feedback on correct shock length. Below are measurements center to center eyelet with full droop and ride height.

Static Full Droop* Ride Height *
Front Driver 22" 20"
Front Pass 22" 20"
Rear Driver 22" 18 3/4"
Rear Pass 22" 18 3/4"

The front has only 2" difference which seems odd. The shop came back and pointed that out as well and is doing some research to verify.

static full droop was measured with jack stand under the frame rails and wheels off the ground. Ride height was sitting on ground, ready to be driven.

I have one of the old Rough Country shocks I pulled off the rig when I bought it. Not sure they were right either it was 23" uncompressed and 17" fully compressed.

Does anyone have any droop / ride height measurements from their vehicles they'd be willing to share. Or recommendations if I'm measuring incorrectly.

Stick with the Bilsteins for what your intended use is, and with the truck just sitting in the driveway, measure eye to eye as instructed when ordering. I bought mine through BJ's, process was super easy, and the price was much better than trying to replace the existing worn out adjustable Rancho shocks.
Me too intend to use my GW 95% or more road use, with light trails, and no rock crawls or difficult terrain.
