The M55 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.

The M66 spring packs lift the rear 1.5″ compared to stock. These have a 450 lbs. higher load capacity for trucks with a shell, tool box, tent, etc. that are carrying more weight all the time. If you’ve got a Trail or Overland rig, these are the springs for you. 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.

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.

The F85 mini-pack is available at a lower cost and replaces the factory over-load spring with a 3 leaf pack for 1.5″ of added lift. This is better than using a block or add-a-leaf that stiffens the ride in this price point. This converts the stock 2-stage leaf springs to a progressive design.

The J66 spring pack lifts the rear 1″ 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.

The U402 spring packs lift the rear 2″ compared to stock. These have a higher load capacity for trucks with a shell, tool box, tent, etc. that are carrying more weight all the time. If you’ve got a Trail or Overland rig, these are the springs for you. 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. They are available in 3 variations based on added load capacity ratings.

The K37 spring pack lifts the rear 2″ 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. These are for single and double cab trucks and require our longer shackle as the stock shackle is too short.

The U748 spring pack also lifts the rear 2″ compared to stock. These have a higher load capacity for crew max trucks and trucks with a shell, tool box, tent, etc. that are carrying a little more weight all the time. If you’ve got a Trail or Overland rig, these are the springs for you.

The J1 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 M27 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.

• This is not compatible with vehicles equipped with electronic adaptive ride control suspension systems.

The U182 spring pack lifts the rear 3″ and the F87 lifts the rear 4″ compared to stock. We recommend the U182 with our 99-06 6.5 kit and our long-travel kit on the 07-18 trucks. 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.

Combine this with one of our Camburg shackles for better performance, more wheel travel and higher strength.

These require using longer shocks intended for the amount of lift.

The K80 spring pack does not lift the rear of your 10-14 Raptor when removing the factory block. The K96 spring pack lifts it 1″ over stock when removing the factory block. They 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. This kit also eliminates the factory block for less axle wrap and also allows for more wheel travel.

For Overland or Chase trucks the K96HD springs have a higher load capacity when constantly running around with around 500 lbs. in the bed. Great if you’re running around with a tent setup or shell with some gear.

We CNC machine these in-house from 6061 aluminum, then have them bead blasted, anodized and laser etched. We include the necessary metric hardware.

For serious off-roading we recommend our air bumpstop kit using FOX or King 2.5 bumpstops for increased bottoming control.

The L83 spring pack does not lift the rear of your ’17-20 Raptor when removing the factory block. The L84 spring pack lifts it 1″ over stock when removing the factory block. They 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. This kit also eliminates the factory block for less axle wrap and also allows for more wheel travel. We recommend using longer shocks intended for the amount of lift with the L84 springs to maximize wheel travel.

On F-150’s the L83 spring pack will lift the rear 1.5-2″ with the factory block removed and requires longer length shocks. We do not recommend the L84’s on F-150’s.

For Overland or Chase trucks the L83HD and L84HD springs have a higher load capacity when constantly running around with around 500 lbs. in the bed. Great if you’re running around with a tent setup or shell with some gear.

We spent a lot of time with Deaver Spring designing leaf springs for optimum wheel travel and performance. We offer two different springs based on how you’re building your truck. We offer a “prerunner” and a “race” spring setup based on the load capacity needed. One spring doesn’t work for everyone.

This race and BITD 7100 class championship winning kit has been used over the years on serious prerunners and race trucks in the deserts of California and as far as the Dakar rally. A limited travel variation of this kit was also used on the 2017 Tacoma we raced in the 2017 Mint 400 in the 7300 class.

This suspension kit is for the serious builder/enthusiast  and is intended to be used with a bed cage and 2.5-3.0 x 16-18″ travel shocks through the bed along with FOX or King bump stops. Their is quite a bit of work involved with installing these parts and is not an entry level install.

• Yields up to 19″ of wheel travel
• Bolt-on front and rear hangers
• Deaver 62″ leaf springs
• Race and championship winning design and performance
