lift kit advice

Finally looking into a 4" (all spring) lift kit, and I am looking for some advice, first
-What is the difference between the 52" and 56" rear springs?
-Am I better off with the adjustable drag link or a new raised steering arm (hated getting that thing off when I put my new axle in...dreading doing it again)
-I am not hearing the best news about rough/tuff country kits, and for the same price superlift seems about comparable, how is the ride/overall satisfaction?
-Am I better off getting the steering stabilzer setup included in the kit? (looking to put 35's under the truck).

Re: lift kit advice

you better be looking at kits for the 67-72 trucks because your 52" vs 56" question is usually about the kits for 73-87 trucks. the 56" springs came on the rear of 73-87 3/4 ton and 1 tons whereas the 52" springs were on the rear of 1/2 tons.

I'm by no means a 67-72 expert but I'm not sure if the rear spring length was the same from the 67-72 trucks to the 73-87's. I do know the front springs are shorter on the 67-72's vs the newer trucks. Make sure the kit you are going after is not for the 73-87's.

Re: lift kit advice

Is this lift for that K20 you list in your signature?
Measure what you have on there now.
From eye to eye on the current spring and buy the same one.
I am happy with my Superlift springs, the more leafs the better the ride will be and thoes teflon friction pads are suppose to help the ride also..

my 68 has different rear spring (56"?) than a 68 K-10 (52"?) that's why I can 't get a full spring kit

Lots of guys like the tuff country, it's a 3/4 ton truck so you are gonna be stiff unless you go with the expensive Skyjacker lifts (so i've heard)

You should get a dropped pitman arm or raised steering arm, i agree to it being a PITA to remove the steering arm but maybe it will be easier since you have had it removed before. I think that you will need an adjustable draglink as well if you don't have one now.

You can always add a steering stabilizer later but with 35" it might not hurt to buy it now.

Re: lift kit advice

Chooseing which spring pack to use will depend on your useage. I've ran Superlift's superride 2.5" and Tough Country's EZ ride 2" in my '71 long box. Both comparable competitors however my current 2" EZ rides a little smoother. It performs well on all terrain except the roughest where the nose dips on landings and big whoops under big block wieght, and a half cord of wood is all the rear can handle. The Super handled everything off road well, but rattles the fillings out of my head on the street and washboard. I did not experience this as much with the longer springs in my '79. I use Bilstien light duty monotube gas shocks in all comparisons to keep the suspension testing even.

If I was to keep the stock suspension set up I would run the EZ ride, but add an airbag out back for towing and hauling assistance. I have bigger suspension plans in the works though that I'm looking forward to.

Hope i was able to help you a little. Good Luck -steve

Re: lift kit advice

I want the best of both worlds: Rigid enough to haul weight without bottoming out, and soft enough to be enjoying to ride in around town. The problem is, I don't think it is acheivable with a 52" spring.

I had a Rough Country in my 71 Blazer I used to own. I bought it because they have the reputation for being able to haul weight. I thought the ride was rather rough. I have a freind who is a small contractor. He had a Tuff Country lift put in his pickup, and he would bottom out whenever he hauled his enclosed job trailer. Said the ride was fine when he was empty. There was a guy in town that had a 6" Skyjacker lift in his pickup. He loved it. But, he only drove it empty around town or 4 wheelin.

I would love to hear what other's have to say. I am still in search of the perfect lift.

Re: lift kit advice

do the soft springs and air bag helpers as stated above. We used them on the farm for the spray truck and they are nice...

Re: lift kit advice

I have a rancho 4" w/ rear blocks. The front springs are pretty stiff and I don't like the blocks.
When i converted to power steering I made my own shorter drag link.
Don't do what I did. You should get a full spring kit, or shackle flip.

When looking for 4" or more of lift I agree to do a shackle flip and use a stock spring pack if its not saging. I also stay away from blocks. Under power they allow too much leverage on the rear end leading to axle wrap. -steve

Re: lift kit advice

I'd agree with using a shackle flip out back. you end up usng the same spring (again make sure it's not worn out/sagging) so the load capacity is the same, but the ride gets soo much better. It's a much softer ride on mine than before I did it. My only unknown is heavy hauling since mine is a K5. Most I've had in there is camping gear/coolers and some wood to burn. I don't remember it sagging under what load I had on it.

Using a shackle flip shouldn't hurt the load carrying ability, but I can see it could squat a little more since the spring would flatten out easier under a heavy load of a full bed of wood or other matieral. Like others, air assist bags might be the best way to get the load capacity back.

Towing/hauling need heavier springs, where as when we want a comfy ride we need soft springs. You can't get around the two facts. You best bet is a compremise with soft springs for everyday comfort and some air bags to stiffen up the rear when it's loaded.

Thumbs up Re: lift kit advice

Be careful what kit you buy from TuffCountry. They do make at least two different 'stiffness' springpacks. I bought the EZ Ride 4" for my K20 and I'm very happy with it. The best thing (in my opinion) about TuffCountry suspensions is that they have nailed the problem that most other companies have with the height balance front to rear on the 67-72 trucks. My truck sits perfectly level front to back. None of that 'nose up in the air' look that most other lift kits give you. I'm not knocking that look, its just not what I wanted for my truck.

Whatever you do, NEVER, EVER, NEVER order your TuffCountry kit through J.C. youknowwho!! What a friekin' mess they made out my order. And it only took them 4 months to get the wrong kit to me, TWICE!!! Thank God I was able to call TuffCountry directly and get the whole mess straightened out.
TuffCountry was very good to do business with.

Re: lift kit advice

I was just looking at lift kit's myself and found rear 4" superlift springs for $142.00. Just thought it was odd that that you can buy a kit with front springs and rear block and add these springs cheaper then you can buy a kit with front and rear springs. www.performancecenter.com
