Description
The PMF Suspension Alpha 8" Lift Kits are intended for the customer looking for a comfortable street ride, excellent towing authority, and a stable rear end for higher hp platforms.
PMF designed these kits around 2 basic principles. They upgrade the front to a quality dual rate coil spring which will provide a nice smooth ride on the street and improved offroad ability offering an additional 3+" of travel over a stock. The rear is designed around the stock rear spring.
The '08+ trucks come stock with a leaf pack that offers a great compromise between ride quality and towing capacity. With the Alpha series, the rear spring will be supplemented with a traction bar kit to give it a stable base when towing or any other performance scenario.

Front Axle:
With PMF 8"+ systems, they typically use a 4-link up front to keep good link arm geometry for a stable, comfortable ride. PMF's design will also give you the most control over axle and wheel hop—as well as keep your frontend planted for even the most brutal 4-hi launches or sled pulls.
Trackbar:
This kit comes standard with PMF's Direct Replacement Adjustable Track Bar. This is a direct plug and play setup. This a heavy duty trackbar is constructed from 1.5" OD .250 DOM with an oversized 1" QA1 heim joint. Most other manufactures will use a poly or smaller heim joint.
With an oversized joint such as what PMF uses, you will get the most durability and least worry of steering related problems. With this kit you have an option to upgrade to PMF's HD Solid Mount Track Bar. This eliminates the lower axle side ball joint style mount for great strength, higher misalignment capability, and the ability to rebuild the joint.
Rear Block:
The rear end is designed to retain your OEM leaf pack in order to maintain factory payload capacities. To gain the additional height, PMF uses a traction block kit with a user selected height to allow you to get the exact stance you desire.
The front springs uses in this kit are designed to sit level with a 8" rear block. The rear system comes standard with PMF's Stage 2 Gusseted traction bar kit to prevent any concerns of axle wrap or wheel hop that both high hp trucks and tow rigs will appreciate!
Ubolts:
This kit comes standard with 3/4" u-bolts. This is a HUGE upgrade over the strength of the OEM 5/8". When selecting the u-bolts, choose either a single rear wheel (SRW) or dual rear wheel (DRW).
Leaf Pack Type:
Determine what type of leaf pack you have. A standard leaf pack will consist of a leaf configuration where the top most leaf runs full length from eyelet to eyelet. A standard leaf pack will have a thickness of 2-3". If your pack is thicker than this choose the "top mounted overload option".
Shocks:
PMF has many different shock options available. All of their shocks are valved specifically for this application. For the customer looking for some improvement in looks and performance the 5100 shock is a great all around buy.
