Complete high-energy friction set for a GM 6L80 rebuild: all five clutch packs, C1-2-3-4 through low reverse, 2010-up units.
If your 2010-or-later Silverado, Sierra, Tahoe, Yukon, Escalade or Camaro has a 6L80 that flares on the 2-3 shift, slips into fifth, or takes its time finding Reverse, the friction material is often the part that has given up. The BorgWarner 34352KIT is the full friction set for that rebuild in one box: 25 high-energy plates covering all five clutch packs, from the 1-2-3-4 clutch through low/reverse. BorgWarner is an original-equipment friction supplier, so you are stacking OE-grade material rather than a mix of aftermarket packs ordered one drum at a time.
The 6L80 is a clutch-to-clutch six-speed with no bands. A simple planetary up front and a Ravigneaux compound set behind it produce the six ratios, and five multi-plate clutches decide which members are driven or held. Every shift releases one clutch while applying another, timed by pressure control solenoids the TCM adjusts as parts wear. Here is what this kit puts back into each pack:
The waved plates in the 1-2-3-4 and 3-5-R packs cushion apply and help the plates separate cleanly on release, which matters because those two clutches work in almost every gear.
A burnt 3-5-R pack is the most common reason a 6L80 comes apart, but the cause is not always the frictions themselves. GM bulletin 09-07-30-004J traces many of these slips to a cracked 1-2-3-4/3-5-R housing that leaks apply pressure, and a new set of plates will burn again in a cracked drum. On 2010-2015 Camaros, GM also documents a cold 2-3 flare caused by trapped air in the 3-5-R circuit that no rebuild fixes. Read the 3-5-R clutch failure guide for the drum air test, and run through the 6L80 common problems guide to rule out valve body, TEHCM and converter shudder complaints first.
This kit is listed for GM 6L80 units from 2010 up, which takes in the GMT900 and K2 trucks and SUVs, the fifth-generation Camaro automatic and the Escalade. The 6L80 changed plate counts and thickness during production, so count what comes out of each drum and match it against the counts above before you assemble anything. The 6L90 uses heavier internals and is not covered here. For a 2006-2009 unit, look at the sibling 6L80 clutch module for 2006-2018, and browse the full 6L80 parts collection for drums and hard parts. If you are unsure, send us your year and VIN.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the friction plates only: 25 high-energy frictions across all five clutch packs. Inspect your steels and replace any that are heat-blued, scored or coned.
It is listed for 6L80 units from 2010 up. Earlier units can differ in plate count and thickness, so for a 2007-2009 truck count your plates against the kit or send us your year and VIN before ordering.
Only if the drum is sound. A cracked 1-2-3-4/3-5-R housing leaks pressure and will burn new plates quickly, so air-check the housing during teardown and replace it if it leaks.
It is listed for the 6L80. The 6L90 has upgraded internals and a longer case, so do not assume the plate counts match.
Dexron VI. Soak the new frictions in it before assembly, fill and check the level hot at the check plug, then reset the transmission adapts and drive the relearn.
