52” Pro Comp Springs

Post by Rory »

Has anyone used Pro Comp 13311 springs on their early Wag? Supposed to be a 52” spring for GM applications but I’m thinking with the right bushings it should work on the early post mount rigs…

Hi Rory.
Did you end up using the 52" GM springs? I am looking for a lift solution for my 69' J3000.

I did. Changed out the bushings to fit the front post and rear shackle. Worked out pretty good. See before and after below.Image

The front is SOA with a stock height spring for a 68-72 Suburban, rear is 4" lift for the same application. Before pic is with 31" tires, after is with 33".

I used 52" GM springs with Ford ranger shackle brackets on both ends of the rear springs in my early J-truck and eliminated the post mount suspension, as that's what i assume you have. Works phenomenal. Measurements may be different as far as placement on a Wag though vs. a truck. But the concept is the same. https://www.fsjnetwork.com/forum/viewto ... 12&t=18528
