Rough Country 4" Lift Kit for 1977-1987 Chevy C20/K20 & GMC C25/K25 with 52" Rear Springs - 25030

If you're looking to give your truck a serious boost, check out Rough Country's 4" GM Suspension Lift System. This kit isn't just about looks—it raises the front to match the rear, leveling things out and giving you that rugged stance you’ve been craving. Plus, it really does improve ride height without compromising on comfort. Trust me, it’s a solid upgrade.

So what’s in the kit? You get a set of front lifted leaf springs that add height while keeping the ride quality smooth. No one wants a bouncy ride, right? The rear leaf springs and brake line brackets included in the package help maintain optimal angles, so you’re getting a factory-like feel even after the lift.

And let's talk shocks. This kit comes with Rough Country's N3 shocks, which are designed for both off-road adventures and those long highway drives. They’ve got this 10-stage variable high-pressure nitrogen charge that really makes a difference. The 18mm spring-loaded piston rod and the 54mm shock body help in cooling faster, which means you get better performance when you really push it.

Thinking about wheels? This lift kit has you covered. You can fit up to a 35" tire with the right wheel backspacing. Just keep in mind that some trimming might be needed depending on your tire choice. For example, if you go with the 35x12.50R15 on a 15x8 wheel, you’ll need to do a bit of trimming to avoid any rubbing.

And here’s the kicker: Rough Country backs this lift system with a Lifetime Replacement Warranty. That’s peace of mind right there.
