Calmini (www.calmini.com) offers a value-priced 5.5-inch drop-bracket kit that will allow fitment of 33x12.50 tires, and Fabtech Performance Suspension (www.fabtechmotorsports.com) has a kit to increase ride height by 6 inches.
Total Chaos (www.chaosfab.com) builds a sweet tubular upper control arm designed to help improve droop while adding caster adjustment at the same time. In addition, the company offers the only 2WD front Fox coilover shock for the platform.
Radflo (www.radflo.com) builds Frontier-specific front coilover shocks (2.0 or 2.5) designed to improve performance both on- and off-road.
Deaver Spring (www.deaverspring.com) has both a rear minipack and a full-race-style leaf spring available for the '05-'08 Frontier. We've tested the minipack and will say it significantly improves ride quality over stock.

 The potent 4.0L V-6 engine...  The potent 4.0L V-6 engine churns out a respectable 265 hp and is by far the better choice for buildups. The combination of low rpm grunt and top-end power impresses us in stock form, let alone when coupled to Stillen's screw-style blower as shown here. This blower arrangement is the only one available and tacks on an additional 93 hp at 6,000 rpm as measured at the wheels. |  We have yet to see this latest-generation...  We have yet to see this latest-generation Frontier receive a solid-front-axle swap. We think the rack-and-pinion steering system deters many people. Not to say it can't be done; we just haven't seen it yet. This custom IFS kit was built by the now-defunct Spencer Low Racing, a company once well known for exclusively specializing in Nissan componentry. |  The Dana 44 rear axle is decent...  The Dana 44 rear axle is decent for a pickup of this size; just don't expect it to hold up to anything bigger than a 35-inch tire. The front differential is another variation of the Dana 44. It features an aluminum housing with splined female outputs. Unfortunately there were no aftermarket gear ratios available for this centersection as of press time. |
