2011-16 4.5" Alpha

Front Axle:
For the front end you have two options.  First we have our Long Arm 4-Link.  This is designed to give you the most control over axle and wheel hop.  It will keep your frontend planted for even the most brutal 4 hi launches or sled pulls.    The other options is to use of our Adjustable 3-Link Arms.  With these, you will notice tighter steering response, better street characteristics, and a more comfortable ride.  The increased strength of the link arms will have better control over the axle and allow for more articulation and shock absorption offroad.  This will make for smoother operation when hitting anything from potholes to whoops!  Regardless of which option you choose you will have the ability to adjust castor to your desired specs.  Front end steering geometry is perfected using a heavy duty drop trackbar bracket and drop pitman arm. 

Optional Trackbar:
  This kit is available with our 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" FK heim joint.  Most other manufactures will use a poly or smaller heim joint.  With an oversized joint such as we use you will get the most durability and least worry of steering related problems. 

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, we use 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 5.5" rear block.  The rear system comes standard with our 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 5/8" ubolts.  For high hp and performance applications we recommend upgrading to the 3/4" ubolts.  This is a HUGE upgrade over the strength of the OEM 5/8".  When selecting the ubolts 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".  A truck with a "top mounted overload" will have a small spacer between the main pack and the top overload which is not connect to anything at each end.

Shocks:
We have many different shock options available.  All of our 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.  The 5160 steps up its game and offers a resi.  There is a definite improvement in on and offroad performance.  The seal orientation on these is better for salty and harsh environments.  For the customer looking for the ultimate performance we offer our custom tuned King 2.5 shock package.  These are setup to give you the absolute best on and offroad performance!
