Looking to improve the rear of your truck? We use the best leafs springs out there manufactured in the USA by Deaver Spring who’s been in the business for over 100 years.
The J-1 mini-pack is available at a lower cost and replaces the factory over-load spring with a 3-5 leaf pack for 2″ of added lift and progression. This is better than using a block or add-a-leaf that stiffens the ride in this price point.
The M-27 spring pack lifts the rear 1.5″ compared to stock. These are more progressive for better bottoming control when off-roading but plush when driven on the street for a much better ride compared to stock springs both on and off-road. On Trail Boss/AT4 edition trucks, these lift them 1″ compared to stock.
The springs pivot on polyurethane bushings versus rubber which allows for better articulation and longevity and come with stronger u-bolts.
These require using longer shocks intended for the amount of lift.
