looking to stengthen the torque arm and also drop weight within a reasonable price range. what do u guys suggest

 

Buy an aftermarket adjustable TA...Spohn, SLP, BMR, Random Tech...all have good ones....Those using stock mounting positions go for $300ish...this will help you launch much better by setting the pinion angle correctly and adding strength to your suspension...most are heavier than stock, but the improvements vastly outweigh the weight gain...if you're concerned, just take out your back seat, or drop weight elsewhere...
