    i'm going to purchase a set of lifted 52's for the front of my rig, and i can get a decent deal on a set of the pro comp springs. Now my question is that summit lists the spring rate at 280lbs/in., and i was wondering if that was enough for up front? I think tuff country springs are 295lbs/in. but i'm wondering what you guys think about running these up front? I have a small block, and no winch yet, but do plan on putting one between the frame rails sometime soon.

    TC EZ ride 4" front springs have a 325 .lbs rate. Higher for the 6" and HD of both.

    Yeah, that's the question, isn't it. hard to say. There are mixed opinions of stock 52's, up front. I don't know what the rate is on the stock ones. I finally chose to get some TC EZ ride 6" springs, and will relocate the rear mount for the travel/flex.. while still having a spring that I know won't be crazy soft for the road. Seemed like a plan to me, but don't know how the results will be, yet. I was also worried about tr/dl contact with my ORD high-steer.. so it seemed like a good set up to go with.

    I'm sure someone who's running something like that up front will chime in with some actual results. Good luck.

    im going to be running 4" lifted 52's up front with the overload removed. that should give me about 7" lift or so which is exactly what im going for. all of TC's 52's have the same spring rate, on their site it says 405.

    i went on pro comps site, and they listed their spring rates at 342lbs/in. for the 6" lift.. i think summit has their stuff mixed up.. any how, that is a little better desirable rate i think for the front.. thanks for all the help and input..

    from the TuffCountry website:

    GM 1/2 & 3/4 ton 4wd 73-87 EZ-Ride 6" 4 465 18670

    i thought on here they were recorded as 295, guess not.

    Some time ago I posted the rate & Rancho p/n for a 4" Pre-runner spring that is not listed under the application, only in the numeric listings. Just tried to find it for reference & can't. Wish I could as those springs ride extremely nice & it'd be nice to have that rate number for comparison.
