I received my 2.5″ progressive coil springs yesterday – quick shipping after placing the order online. Tonight I calculated the spring rate on them and I think they’re just about what I’m looking for. It’ll be awhile until I get them installed but I’m looking forward to giving them a workout.

I just recently bought the 5.5 inch for my SAS Tahoe. They fit perfectly and the ride height is just how I wanted it. There is a ton of flex and the ride quality is superb even without a front sway bar. Would recommend to anyone planning to SAS using a 66-77 bronco front end.

much smoother ride than my old Rancho Lift
Bill (verified owner) –
Purchased 3 1/2” front springs. Excellent quality, excellent ride improvement over the 90’s lift that was on the truck. Highly recommend.

Took off some other brand 5.5” springs and put on 3.5” Duffs Springs. Love the ride these give. Not been off-road with them but on the road it’s a good smooth ride and handles great.

The springs gave my front end a whole new look and a better feel on & off the road!
Big time upgrade!

I last replaced my front coils with Duff springs some 37 years ago on my 70 Bronco. And I bet I would not have needed to replace them if not for a higher desired lift. So I knew there was only one brand I wanted to buy. I think progressive is the way to go (rather than linear) and these were consistent such that they fit just the same on both left and right. Great lift and ride.
