Will Hellwig #991 help with rear sag when trailer is attached to truck with load distributing trailer hitch on my 2002 tundra
The Hellwig 991 will add 2000 lbs. of load support to the rear end. As long as the tongue weight does not exceed 2000 lbs. it will definitely help with keeping the rear end from sagging with a trailer attached.

great product
overall this product works great. The only thing they need to fix is the hardware for the kit. the lock nuts prevent you from taking them off of the vehicle. overall though this kit is really doing me some good.
