Rough Country 4" Lift Kit for 1977-1987 GM K10/K15 Pickup K5 Blazer - 145.20

Q: What else do I need for this lift...do I need brake lines..I have a 88 GMC JIMMY just don't want to get the project started and have to order more??

I installed this lift on 89 gmc jimmy, it relocates the rear brake lines, the front ones are long enough

Q: what shocks do we use on a 1987 k-5 blazer with quad shocks and a 4 inch lift

Heavy soft dampening shocks that the travel is long enough for full travel of the lift
