HD Forged Adjustable Track Bars0-6” Lift

.      

Our JK/JKU: HD Forged Adjustable Track Bars are 230% stronger than the stock piece making them the strongest track bars on the market!

.      

FEATURES & BENEFITS:

.      

  • HD Forged Adjustable Track Bars are 230% stronger than factory track bar
  • Bolts onto factory track bar brackets
  • Front Track Bar works w/ the raised front track bar bracket on our Tera HD Front Axles as well as the Front Track Bar Frame Drop Bracket (# 1953000)
  • Rear Track Bar works w/ Rear Track Bar Axle Brackets (2.5" Lift: # 1954776; 3-6" Lift: # 1954777)
  • No cutting or welding required
  • High-quality, maintenance-free factory-style bushings w/ an additional rate plate for superior handling and responsive control

.       

HD Forged Adjustable Front Track Bar

.       

The front axle experiences tremendous amounts of lateral force while turning and those effects increase exponentially during off-road driving. The TeraFlex JK/JKU: HD Forged Adjustable Front Track Bar withstands these abusive side loads to drastically improve steering response and handling. It also allows lateral adjustment of the axle for proper axle alignment as well as cycling through full suspension travel without interfering with other components.

.           

.  

HD Forged Adjustable Rear Track Bar

.      

The TeraFlex JK/JKU: HD Forged Adjustable Rear Track Bar keeps the rear axle correctly centered under the vehicle as the suspension cycles through its full range of movement. It also maximizes rear passenger spring clearance without interfering with other components.

Front Track Bar Bracket Gusset

Beef up your stock front track bar bracket with the TeraFlex JK/JKU: Front Track Bar Bracket Gusset. Prevents “egging out” of the mounting hole. A loose track bar can cause crucial suspension points to bend after long-term heavy use.
