Comparing Timbren Rear Suspension Systems TGMRYS4 and TGMRG25C for 2005 Chevy Suburban

Question:

Im looking at Timbren Rear SES for my 2005 Chevrolet Suburban 1500 Z71 4WD, and I am a little confused by the listings. Full disclosure: I contacted Timbren, asking which kit is correct for my application, and their recommendation contradicted etrailers listings. Timbren indicated to me that their GMRYS4 kit is the kit that they recommend, while etrailer consistently lists GMRYS4 for 2WD applications and GMRG25C for 4WD. Could you clarify this for me, please? Thank you!

The correct Timbren Rear Suspension Enhancement System for a 2005 Chevrolet Suburban part # TGMRYS4. The Timbren Rear Suspension Enhancement System part # TGMRG25C will fit as well but is taller so it will engage sooner.
